Update to bsnes v061 release.
Please keep in mind that bsnes v060 remains the current stable release. v061 has been released as a work-in-progress build. As such, it is only available at Google Code.
I am releasing this WIP to allow the public to test out and comment on the new XML mapping system, as well as the integration of mightymo's cheat code database into the cheat editor. I would greatly appreciate feedback on these two on the forums.
There are some important issues with this release. The biggest is the move to C++0x. This requires GCC 4.4.0 or newer to compile, thus it is not currently possible to build this on OS X using Xcode. Nor would it be possible on certain BSDs or older distros. If you have an older compiler, please stick with v060, or use a binary release where available.
Another issue is that TDM/GCC 4.4.1 for Windows crashes with an internal compiler error when attempting to generate a profile for the DSP-1 module. This is a bug in the compiler, and not in the code itself. The workaround is to simply omit profile-guided optimization for this one object.
Lastly, there's also a known bug in the memory mapping. If you load an SA-1 game, SuperFX games will not load properly afterward unless you restart the emulator. I'm looking into the cause now, but it didn't seem serious enough to hold up a WIP release.
So, yes. If you want a good gaming experience that's been fully tested and stable, please stick with v060. If you want to see some bleeding edge features, I'd appreciate feedback on v061. Thanks for reading this.
Changelog:
- added mightymo's cheat code database, access via "Find Cheat Codes" button on cheat editor window
- added an option to temporarily disable all cheat codes quickly
- debugger now properly uses S-SMP IPLROM when needed for disassembling and tracing
- indexed indirect read opcodes in the S-CPU were testing for IRQs one cycle too early [someone42]
- fix an off-by-one array iteration in S-PPU OAM rendering [PiCiJi]
- added some implicit linked libraries to linker flags for Fedora [belegdol]
- moved from C++98 to C++0x, resulting in substantial code cleanups and simplifications
- C++0x: implemented foreach() concept for linear container iteration
- C++0x: implemented concept system using SFINAE and type traits
- C++0x: utilized auto keyword to increase source readability
- C++0x: moved to strongly-typed enumerators
- C++0x: rewrote va_list-based code to use type-safe variadic templates
- C++0x: replaced noncopyable class with deleted default copy functions
- C++0x: replaced custom static_assert template class with built-in version
- C++0x: utilized rvalue references to implement move semantics into string, array, vector and serialization classes
- C++0x: utilized std::initializer_list for { ... } initialization support to lstring, array and vector classes

Update to bsnes v060 release.
This is a long-term stable release. A full changelog will be available at the forum link below later in the day. Also, please note that I have merged all of the various distributions into two packages. The Windows binary package now contains both the profile-optimized (fast) build, and the debugger build. The source code package now contains sources for bsnes, snesreader, snesfilter and supergameboy.
Changelog:
- added Direct3D HLSL pixel shader support [mudlord]
- fixed a signal issue that caused loading games to take 1-2 seconds longer in v059
- 21fx API revised to its final form, S-MSU (public documentation pending)
- worked around QTBUG-7188 to fix multi-file 7-zip file listbox to update when scrolling
- added scale max - normal, wide, and wide zoom modes to fullscreen mode
- added overscan cropping tool (needed for wide zoom mode; useful for developers simulating games on a real TV)
- added "go up one folder" button to file load dialog
- added group (un)assignment to the input settings window
- now honors input.allowInvalidInput setting; defaults to false [Jonas Quinn]
- cheat code editor grays out empty slots
- cheat code editor adds "clear selected" button to quickly erase multiple cheat codes
- to load folders as game images, folders must end in .sfc, .bs, .st, .gb now
- debugger: added S-CPU (H)DMA registers; S-SMP registers; S-DSP registers to properties list
- snesfilter: HQ2x filter is now multi-threaded (scales infinitely: the more cores you have, the less overhead required)
- pixelshaders: added screen curvature shader to simulate curved CRT tubes
- source: lots of code cleanup, as always

Update to bsnes v059r05 release.
Funny, much more effective changes but in a lot less time. The file dialog is just a major pain in the ass, I guess. Had to sit and think for at least two hours just to handle the differences between activate (double-click an item) and accept (click accept button.) Eg if it's a folder, double-clicking needs to go into the folder, but the accept button needs to use that folder. But files act differently, load has the open-folder thing that overrides the default entering of folders, and saving doesn't have any such concept at all. Fun fun fun, but done now. libqb (QbWindow, QbCheckAction, QbRadioAction) is dead; DiskBrowser is dead; HexEditor is dead. They've all been merged into nall/qt now. nall/Makefile-qt goes to the more logical nall/qt/Makefile. The last thing to do is export style sheet defaults into nall/qt to get the spacing of the new file dialog under control. Improved the save dialog, instead of putting the entire path in the box, it only puts the non-directory part, and pulls the directory from the file system mode's root path. I decided not to allow .. and / commands inside the save text box. I just strip all that out. Go to the damn folder you want to save in, sheesh. And before anyone complains about that, note that bsnes doesn't even use the save dialog mode :P Still have to hook up the new folder button to an actual dialog, haven't bothered yet. Since there's plenty of room with the extended width, I'm just going to leave them both visible. nall/qt/hex-editor is pretty much a direct port, no changes. But I intend to make the height programmable, and fork that into a stand- alone, super light-weight hex editor to replace bless (so that I can remove Mono.) Same for check-action and radio-action, direct ports. nall/qt/window is a bit different, binds the geometry outside the constructor. This fixes some issues where certain windows weren't saving their geometry properly, like the debugger properties window. And I think there's some other advantage to it not needing a complicated constructor, but I don't recall what at the moment. Modified GL_CLAMP_TO_EDGE to GL_CLAMP_TO_BORDER, so everyone can try out the curvature pixel shader now. Added it to my pixelshaders pack, but I haven't uploaded a new pack yet, so get it from the other thread for now. I mainly need testing on the new file dialog stuff. Please let me know if something strange is broken, other than the new folder button. |

Update to bsnes v059r04 release.
Eight hours of non-stop work, for the sole purpose of trying to separate the file browser underlying mechanics from the bsnes-specific stuff. So far, it's going quite well. 95% of the functionality is there with only 25% of the code size. Forked the underlying stuff to nall/qt/file-dialog.moc.hpp, which is now designed to support open+save+folder selection natively. Save mode adds a text box to enter your own file name, and folder mode hides the filter drop-down and all files automatically. The top bar now spans 100% of the width. I like it more this way. I also killed the tree view in favor of a list view, for the sole reason that I really can't stand how when you go up a folder and the deeper tree is still open. Since the QFileSystemModel is asynchronous, I can't close the tree nodes when navigating up. The simplifications were needed because it was getting damned-near impossible to edit that mess of a file (diskbrowser.cpp.) Compare to filebrowser.cpp, much cleaner. Now I should be able to add open-folder concept for BS-X, ST and SGB games much easier. And of course, I should be able to offer the base QFileDialog as an option, too. After that, I'll probably export the hex editor to a generic class, and then export the Qb stuff (window geometry save/restore, stock check / radio menu buttons.) Also, I just wiped out Windows XP and put Windows 7 back, just to fix the video tearing issue relating to DWM and ... it works perfectly fine. Zero tearing, zero skipping, zero audio popping. All I did was start bsnes v059.04, set audio sync to the usual 31960, and it was just fine. What the hell are people complaining about, exactly? |

Update to bsnes v034r06 release.
This will probably be the last public WIP, so get it now if you want
it.
http://byuu.cinnamonpirate.com/temp/bsnes_v034_wip06.zip
I used the same "create a child window inside the output window" trick
for Xv that I used for OpenGL, so Xv will now work even with a
compositor enabled.
I also added Video::Synchronize support to OpenGL for Windows. My card
seems to force it on regardless of my driver settings, but maybe
you'll have better luck. That driver had the same issue with
allocating 16MB of memory instead of 4MB (that was due to copy and
pasting of code), so that's fixed too.
This version lowers the CPU<>SMP drifting by an order of magnitude.
You shouldn't notice the speed hit. I can't really get any lower
latency with that, though.
I also restricted the latency range to 25 - 175, with the default
being in the center, 100ms. Quite conservative, given the average we
see is 70-80ms. But you won't notice the difference, and this way we
ensure no popping even in exceptional circumstances by default. 25ms
is doable without video sync and with OSS4+cooked mode, but I
seriously doubt any Windows user will get lower without something
crazy going on with the sound card drivers.
Lastly, I've replaced the 2-tap linear resampler with a 4-tap hermite
resampler. You won't be able to tell the difference, but it's quite
pronounced if you use a waveform analyzer on much higher output
frequencies:
Linear:
Image
Hermite:
Image
Hermite is essentially better than cubic (for which cubic spline is an
optimized version of), as it is better at not going too far away from
the points, so you get a bit less clamping in the extreme cases. But
the difference isn't audible to humans anyway. It's still clearly
inferior to band-limited interpolation, as it will still have
noticeable aliasing of things like square waves and such, but it's
orders of magnitude less complex to implement.
Keep in mind that nobody could tell the difference even with linear
interpolation from the last few WIPs.
----------
Aside from that, I'm pretty much ready to release a new version. If
anyone has any show stoppers, _now_ is the time to say something.
Otherwise I'll probably post something tomorrow or Friday.

Update to bsnes v034r03 release.
New WIP, with _major_ changes to internal header detection.
This should get everything working, if we're lucky. It does get
Batman: RotJ working for the first time, as well as all the fan
translations.
I'm releasing it publicly, as I need all the help I can get with this
one. Windows binary with ZIP+JMA support included along with source
for the penguins.
byuu.org/temp/bsnes_v034_wip03.zip
Do note that I left the console enabled in the binary. It's not a
release-grade version, anyway. But the main reason was to print the
scoring information. If any games fail, I'd like that information
posted. Might be good to note really close passes, as well, so we can
keep an eye on them for future changes. Right now, I'm only aware of
SFA2 that gets really really close.
Basically, it prints the address it tests for a header at, the score
it ended up getting, and the reset vector's first opcode. If the
values are equal, it defaults to LoROM, then HiROM, then ExHiROM. If
the reset vector is invalid, or the ROM is too small to contain a
header at a certain offset, you won't see any output for that line!
That means a lot of times, you'll only see one line output, and
sometimes you'll see two or three. No worries, just assume missing
means total fail. It only prints output for "possible" header
locations.
If you do test, you don't have to play in-game or anything. The second
you see any visible output whatsoever, that's good enough.
Many thanks to everyone who tests in advance :D
----------
Hunter and tukuyomi, thank you for the kind words and localizations :)
I really hate that table on the download page, and I need to go
through and get names out of all of the locales, but I'd like to get
an "Author:" field in that table on the download page. Sorry it's not
there just yet.
----------
Fes, thanks for the feedback.
> Apparently it has a limit of 65535 bytes for string literals.
I don't have a workaround for that. For whatever reason, ISO didn't
add an "incbin"-style command, and I need a platform-agnostic way of
encoding binary data.
Not for v035, but maybe a while after that, I'll use a more advanced
compressor to get the controller below 64kb of string data. Maybe I
can rig my order-0 arithmetic coder onto the end of LZSS for a quick
and dirty size cut. The reason I don't use 0xnn, 0xnn, is because that
takes 5 bytes of source to encode one byte of input, whereas base-64
strings only take ~1.25 bytes. I didn't want those files to slow down
compilation much.

Oops, sorry. Didn't get a warning on GCC, so I overlooked it. This is
now fixed.

First should return the filename, it's just a convenience thing to
allow chaining commands. The second should return result of patching.
I've fixed both now, thanks.

Microsoft really pisses me off by intentionally ignoring stdint.h.
nall/stdint.hpp was meant as a workaround, so that I didn't have to
special case Visual C++. The idea was to not require you to get one of
those third-party add-ons.
So yes, two of those were a mistake on my part, I used stdint.h on
them before I created my own stdint wrapper. I've corrected both.
As for spc_dsp.h, that shouldn't be compiled. That is for blargg's
reference, unmodified S-DSP emulator. The ones modified to work in
bsnes do not require it. And in fact, only src/dsp/sdsp will compile
at the moment due to memory map changes.
> # pEditbox::get_text seems to declare a dynamically sized stack
> array, which CL balked at.
Hahah, yeah, that would be C99 syntax. Very nice, that.
Looks like I was allocating length*2 wchars, too. I don't know why I
was doing that ... I don't think Microsoft's system even supports the
extended Unicode symbols that need more than 16-bits, and even if so,
they aren't likely to appear in the emulator.
Dropped that back to length+1, and made it use new[]/delete[],
instead. That's one horribly inefficient routine by the way, but
whatever, it works for now.
The rest I can't do much about, sorry. Hopefully it'll make it easier
for you to compile in the future. Sorry for letting the port slip, I
just don't have the patience to load VS2k5 again. Software takes like
three hours to install >_< and creates slower code than GCC4 anyway.
If they'd fix their damn PGO support, I'd be all over it again,
though.

Update to bsnes v023 release.
I've recently fixed a bug in bsnes that I feel is serious enough to warrant a new release, even though little else has changed.
I attempted to build this release with MinGW, but ran into problems with profiling and JMA support, so this release was built with Visual C++ once again.
Changelog:
- Fixed serious bug in S-SMP incw and decw instructions -- fixes sound bug in Emerald Dragon
- Added Nach's MinGW fixes -- can now be compiled with MinGW/GCC3 or MinGW/GCC4
- Fixed const char* cast warnings in GCC 4.2, thanks to [vEX] for the feedback
- Updated source to use latest libraries for libco, libui, etc.
- Added new advanced options to adjust aspect ratio correction
- Cleaned up source code a bit

Update to bsnes v022r03 release.
Double post!
I've uploaded a new WIP, which I'll make public (only to this forum,
please don't post about it anywhere else unless you mirror the file):
http://byuu.org/files/bsnes_v022_wip03.zip
This version adds all of Nach's MinGW fixes, updated libco, libui and
libfunctor, cleans up the code that detects if the main window has
focus or not (if not, ignore keyboard input), adds the new makefile
target win-mingw-lui, finally fixes all of the char* conversion
warnings with GCC 4.2.x (thanks [vEX]), and I'm sure there's more, but
I don't remember.
The ZIP includes a Visual C++ generated binary, but it also works
with MinGW GCC4. It won't work with MinGW GCC3 because that one lacks
a C99-compliant vsnprintf function. You can hack your way around that
by editing src/lib/libstring_sprintf.cpp if you really want to use
MinGW GCC3.
You may also need to change the CC / CPP variable names. I went with
the generic names mingw32-gcc and mingw32-g++, but the GCC4 binaries
have -sjlj or -dw2 appended to them. You'll also need to set
-I/path/to/directxheaders, or copy them all into
/path/to/mingw/include, since MinGW seems to ignore the include
environment variable.
And finally, a bit of good news. It appears that MinGW GCC4 builds
binaries that are ~6% faster than Visual C++. That means with PGO
enabled, they should be at least ~16% faster than v0.022 official. If
I can figure out how to hide the ugly terminal window in the
background, I'll start making official releases with MinGW GCC4 from
now on.

Update to bsnes v020 release.
Five months and 43 WIP releases in the making, today I am releasing bsnes v0.020. I'd really like to express my thanks to blargg, for he has written a new S-DSP emulator that is an impressive 32 times more precise than all existing S-DSP emulators. It is now bus-accurate, and should produce bit-perfect sound output to that of a real SNES, excepting very minor, very extreme edge cases. Not only did he do this, he went out of his way to develop a special version exclusively for bsnes to ease licensing concerns and take advantage of bsnes' unique features, notably cothreads. I can't thank him enough. Unfortunately, bsnes has taken a ~10% speed hit over v0.019 by using this new S-DSP emulator, but I must stress the speed hit is entirely due to the way bsnes is implemented. blargg's standalone S-DSP emulator is very, very fast. Anyone is free to take a look at his S-DSP emulator, as he has released it as open source under the LGPL, by visiting his homepage, here.
Unfortunately, the new cross-platform UI is not entirely finished. Some sacrifices had to be made to support libui. Specifically, the following features are missing from v0.019, but will hopefully be added back in future releases:
- Fullscreen support
- Input Configuration panel cannot capture joypad input. Joypad support is still present, but it must be mapped manually through the Advanced panel or through editing bsnes.cfg by hand
- The Cheat Code Editor is missing, but cht files can still be used from bsnes v0.019, and created by hand
- Sufami Turbo support is not accessible from the UI
- The UI on Windows is slightly less polished due to compromises to allow the UI to be readable on Linux.
I am sorry for the rough edges listed above, but I wanted to get a new release out, as it has been over five months since the last release, and I really want the world to be able to experience blargg's new S-DSP emulator.
Changelog:
- Added blargg's new S-DSP emulator, runs at 1.024mhz. Many thanks to blargg for this, as this puts all portions of SNES emulation except for the S-PPU at bus-accuracy
- blargg's S-DSP core fixes bugs in both Koushien 2 (J) and Toy Story (U)
- Corrected all S-SMP cycle timings to be hardware accurate. Thanks to blargg for creating an amazing test ROM that tested every possible opcode
- Corrected S-CPU wai instruction timing, fixes Mortal Kombat II
- Reverted HDMA sync emulation once more to fix Breath of Fire II (G) and Secret of Mana (U)
- Completely rewrote user interface to use libui, which is a wrapper that allows the same code to produce the same UI on both Windows (through the Win32 API) and Linux (through the GTK+ API)
- Corrected $2100.d7 OAM reset behavior, thanks to research from anomie
- Massively revamped the Linux port, should compile with no warnings or errors now
- Added 64-bit support to libco, tested on FreeBSD/amd64, should work on Linux as well
- Revamped makefile with suggestions from Nach
- Improved Linux Xv renderer to use the far more common YUY2 format, which should work on most Xorg drivers, allowing hardware accelerated video scaling
- Completely rewrote config file system. bsnes.cfg is now saved to user's profile folder on both Windows and Linux, allowing multi-user support
- A lot more work has been done behind the scenes, including massive code cleanups and portability improvements
You may download the new version on the main bsnes page.

Update to bsnes v019r09 release.
Alright, I'm in a semi-good mood.
http://byuu.cinnamonpirate.com/files/bsnes_v019_wip9.zip
This one uses the old win32 interface, and adds a new feature I'd
like people with sound troubles to try out. The config file now
contains "audio.latency". Don't mess with "audio.frequency", it won't
do you any good and gets overridden by the speed regulation settings
for now.
The audio.latency is a precise measurement of the millisecond delay
between sound being output by a real SNES and hearing that same sound
in bsnes. It takes into account the current playback frequency, as
well as the three-ring buffering system used by bsnes' audio system.
Formula: sample_latency = CURRENT_playback_frequency / 1000 *
config_file_latency * 3 (so 32khz + 75ms latency means each ring
buffer is 800 samples long). The new formula should make latency sound
better (it's consistent now) on fast / slow emulation speed throttling
settings as well.
I also cut out the fourth ring, since it was redundant. This should
make bsnes appear ~25% more responsive to sound with the same buffer
latency. As a result, I increased the latency to 75ms (it was at ~45
before).
I'd like to know what the lowest good value is that works on 95% of
sound cards, so I can use that. I'll let people with cheap sound cards
increase their latency setting manually (eventually it will be an
option in the GUI).
**NOTE:** this version does nothing for triple
buffering/vsync/whatever. You must _disable_ triple buffering to try
out the latency settings. This version is strictly to test audio
playback support.
I also added in my audio point resampler. Good god, it sounds
terrible. Regardless of the latency setting (either really high or
really low), the pitch difference between each audio ring is
_extremely_ noticeable. The code is there now in
src/ui/audio/dsound.cpp : AudioDS::run_videosync(), if anyone would
like to take a look. I'll hold my breath ;)
-----
Comparisons against ZSNES at this point are rather silly. Aside from
much more flexible timings, it probably has a nice audio resampler,
which I don't. If I faked CPU/SMP clock timings, I could get the SNES
spitting out 60 frames a second and 32khz audio a second. I'm not
going to do that, so I have to figure out how to resample the two. All
of my attempts at resampling video _and_ audio have both failed
miserably to date. I really only need one of those to work to get
smooth video+audio, but both would be nice so the user can decide
what's more important to them.
I don't care to add 2xSaI. I'm planning on redoing the filter stuff
soon to support 32-bit output for Xv, so if someone wants to add 2xSaI
support to bsnes after that, I'll add it in. Otherwise, HQ2x is
superior and Scale2x looks about the same, yet is way faster.
Regarding the IPS thing, exactly. As I said, IPS is a bad format. You
can't tell if you need to patch against a headered or unheadered ROM
unless you read the documentation that fuckheads like Cowering remove
in their ROM sets ("at least it's already prepatched"), or try
patching twice to see which one works. UPS will eliminate both of
these problems. Readmes will be included inside the patches, and UPS
will work regardless if your ROM has a header or not. It will also be
reversible. It'll be better in every regard over IPS, so I have no
reason to support IPS.
Lastly, I don't have any intention of working on fixing DeJap's
patch, regardless of where the problem is, as I have no way to run the
game on my copier. Maybe when and if the last two serious bugs
(Uniracers and Koushien 2) get fixed, I'll take a look at it then.

Update to bsnes v016r52 release.
bsnes now builds with no warnings on Linux:
http://byuu.cinnamonpirate.com/images/desktop082106.png
However, input is not working unless you build the non-
GTK+ port (see below for more info).
I'm planning on releasing next weekend. This will likely be the last
public WIP, unless something major is found before the weekend:
byuu.cinnamonpirate.com/files/bsnes_v016_wip52.zip <-
copy/paste link
> If you can actually get it going fast in an all-in-one window like
> that it'd be cool. I normally just punt and have the GUI separate
> from the emulator output (GTK or Qt for the UI, SDL for the output)
> but it'd be nice for my NEStopia port if I could make it "one piece"
> like the Win32 original
I can. Please take a look at my above sourcecode, and check your
private messages for another note. Specifically, src/ui/video/sdl.cpp
and src/ui/gtk/gtk_mainwindow.cpp. I am able to merge the SDL output
into the GTK+ window by setting the environment variable
"SDL_WINDOWID=%ld", GDK_WINDOW_XWINDOW(mydrawingbox->window).
One important thing to note is that you must not initialize SDL video
until the render window has been realized. Simply showing the window
is not enough. You need to also clear all pending events in GTK+ after
showing the window before calling SDL video init, or it will die.
You can do that with this code:
gtk_widget_show(mainwindow);
while(gtk_events_pending() == true) {
gtk_main_iteration_do(false);
}
However, one problem I am having is that by calling
gtk_main_iteration_do(), it steals all SDL input, and I'm not able to
poll any keypresses. This happens whether I embed the SDL video output
into the GTK+ window or not. The only way to get SDL input is to
ignore all GTK+ events, effectively freezing the window completely.
I don't suppose you'd mind sharing how you got SDL
input working with GTK+ with me?

Update to bsnes v016r42 release.
Ok, one semi-large change if anyone wants to test.
byuu.cinnamonpirate.com/files/bsnes_v016_wip42.zip
This is built for maximum speed. No debugger, PGO enabled, favor
speed, no c++ EH (so no ZIP/JMA), and a new addition: links against
msvcrt instead of libcmt.
By using msvcrt and some evil linker hacks I was finally able to
build the SDL port again on Windows. So now I just need to focus on
cleaning that up so the next release will build on Linux out of the
box. Anyway, I tried it on the non-SDL port for the hell of it, and
noticed not only a 20% drop in EXE size, but a ~10-11% speedup as
well. Only problem is it requires msvcr80.dll, and I have no idea how
common that file is. So, that's what this wip is for. Does this
version work for you, and if it does, does it run faster? A direct FPS
comparison between v0.016 and v0.016.42 would be helpful if you're not
sure.

Update to bsnes v016r38 release.
Ok, this WIP rewrites the input code and modifies the PAL clock speed.
Fairly major changes. Ideally, this will wipe out four bugs without
causing any new ones since wip37.
Bug fixes :
Earthworm Jim 2 (E) - adjusted PAL CPU clock speed.
Please test for *new* sound problems in PAL games
La Wares (J) + Galivan 2 (J) - no longer return 0 when
auto joypad is off for polling $4218-$421f
Super Conflict (J) - added anomie's new OAM RTO findings
to fix title screen
The input code was almost completely rewritten to simulate real
hardware more. As such, it's very possible there are new input bugs.
Ok, so then
byuu.cinnamonpirate.com/files/bsnes_v016_wip38.zip
Please only download if you intend to test games and report feedback.
This version is slower than normal, lacks ZIP+JMA loading, and has the
debugger enabled (that is only useful to me, it lacks a functional
user interface) which slows down emulation even more. eg you're better
off with v0.016 official if you just want to run games.
As always, please don't post this link anywhere else, or
I will be forced to remove the file to conserve bandwidth.
If anyone posts bugs that hasn't tested against wip37, can I please
have someone with wip37 verify/deny the bug presence in wip37 as well
as in 016 official? wip37 isn't on my website because I don't have a
lot of web space to spare.
Thank you to everyone in advance for helping.

Update to bsnes v016r27a release.
Ok, I tried converting the switch/case table to a jump table for both
CPU+APU cores. Results? EXE is 70kb larger, compile time is 5-10%
slower, and speed is identical. Needless to say I reverted that change
back. I then tried narrowing down the cause of the PGO error. Found
out it was Dai Kaijuu Monogatari. If I don't run that, I can build
with PGO. Unfortunately, this is the ROM I use to stress optimize
color add/sub. So as a result, this game will run a little slowly now
(sort of like how Chrono Trigger's OPT title screen effects were
before). But, better one game than all, right?
byuu.org/files/bsnes_v016_wip27a.zip
Once again, please do not submit news about this to an emulation
site. The file will be removed if I notice anyone mentioning it
anywhere.
That will be 20-25% faster than wip27, but otherwise
everything is identical.
DSP1: there's either a bug in op02, op06, or in the getSr/getDr/setDr
functions. We have so far been unable to spot the error and correct
it. Help is always welcome, as always. Please consider DSP-1 support
as not being there at all. I doubt any games will work right with it
right now :(
This is how interlace works :
I call each frame a "field", meaning even or odd fields
on your television / monitor.
When interlace is off, I draw to the even fields every
time, so you don't notice anything.
However, when interlace is on, I alternate between which one I draw
to each field. So depending on your frameskip, this can cause serious
problems for interlace mode. I also only physically draw to "half" the
resolution each field, much like a real TV would. This makes 512x448
mode just as fast as 512x224 mode.
I can't think of an easy way to cheat the system with frameskipping.
Luckily, very very few games use interlace at all. Most use hires
512x224 and that's it.

- Fixed a bug in CPU BCD math, fixes numbers in SimEarth, thanks to DMV27 for info
- Rewrote the windows port from scratch
- -- Added triple buffering support (buggy)
- -- Added DirectInput (joypad) support, allows both keyboard and joypad to be mapped to the same SNES controller button. Only one controller supported for this release, will be improved shortly
- -- Added pause key (mapped to Pause/Break)
- -- bsnes no longer consumes CPU time when paused or when no ROM is loaded
- -- Updated DirectDraw to 7, and added video mode configuration options to configuration file
- -- Video modes can specify screen width+height, refresh rate, and render width+height
- -- Added CTRL+[1-0] hotkeys for swapping video modes
- -- Added +/- hotkeys for adjusting frameskipping rate

Update to bsnes v014 release.
This version adds speed regulation, greatly improves PPU rendering, and increases speed by ~30% over the previous version.
Changelog:
- Rewrote offset-per-tile mode emulation, should be correct now. Fixes Chrono Trigger, Contra III, Tetris Attack, etc.
- Fixed a bug with HDMA occuring during interrupts. Fixes Tales of Phantasia souond test screen
- Updated compiler to Visual Studio 2005, and enabled profile guided optimizations
- Added conditional compilation of debugging functions (faster without them)
- Added conditional compilation of core classes as pointers (allowing polymorphism) or objects (allowing inlining). The latter results in a speed increase
- Small fixes to BG and OAM rendering routines
- Corrected sprite tile bounds wrapping
- Corrected sprite rendering in hires video modes
- Rewrote color add/sub routines, should be correct now. Fixes Illusion of Gaia menu, etc.
- Optimized video blitting routines, will temporarilly break mixed video mode screenshots
- Prevented selecting menu options via return key from being recognized as keypresses by the emulator
- Added system speed regulation (60hz/NTSC or 50hz/PAL)! Many thanks to kode54, GIGO, and Richard Bannister for their assistance
I disabled the debugger and polymorphism, and enabled profile guided optimizations for this build, to maximize speed. The debugger and polymorphism can be re-enabled via uncommenting the respective #defines in src/base.h and recompiling, or bsnes v0.013 can be used. I may start releasing two separate builds in the future... not sure yet.

Update to bsnes v013 release.
- Greatly improved HDMA timing and accuracy with help from anomie and DMV27 -- fixes bugs in Energy Breaker and Street Fighter Alpha 2
- Fixed a problem with color add/sub code -- fixes opening battle in Tales of Phantasia and clouds in Energy Breaker
- Temporarily added DMV27's bugfix for the DSP KON register -- fixes sound in Der Langrisser, but this is not a hardware-accurate fix
- Disabled VRAM writes outside of vblank -- fixes Hook, but breaks many PD ROMs and fan translations (Roto's BS Zelda hack, Gideon Zhi's Ys 4 translation, etc). I might add an option in the future to toggle this behavior, but for now these games will no longer work. Please keep in mind these games will not run properly on real SNES hardware, either.
- Improved frameskipping code thanks to a suggestion from Richard Bannister
- Misc. other code cleanups and improvements (notably in the color table generation code)
- bsnes is now endian-safe and runs on Mac OS X
- Added caching support for window clipping tables resulting in a slight speedup. Please let me know if you spot any errors as a result of this change.

Update to bsnes v012 release.
Changelog:
- Added S-DSP emulation
- Added sound output support via DirectSound -- no sound buffering though, so sound is muted by default
- Added option to record raw sound output to WAV files
- Added multiple color adjustment filters to the video output
- Added mode3/4 direct color support
- Added mode7 direct color and mosaic support
- Greatly improved mode7 rendering algorithm thanks to anomie
- Fixed mode7 screen repitition and EXTBG effects
- Greatly increased accuracy of NMI and IRQ timing, and emulated many newly discovered hardware quirks involving the two
- A few speed improvements courtesy of Nach for profiling the code for me
I'm now looking for assistance with sound buffering. Specifically, I need help modifying the DirectSound code to allow the emulator to be ran between 50%-400% normal speed, while keeping the sound output relatively good. If you have experience with this and can help, please get in touch with me (setsunakun0 at hotmail dot com).
