Fixes SuperFX fmult, lmult timings; rambr, bramr and clsr assignment
masking. Implements true GBA ROM prefetch (buggy, lower test score, but
runs Mario & Luigi without crashing on battles anymore.)
byuu says:
This WIP scores 448/920 tests passed.
Gave a shot at ROM prefetch that failed miserably (ranged from 409 to
494 tests passed. Nowhere near where it would be if it were implemented
correctly.)
Three remaining issues:
- ROM prefetch
- DMA timing
- timers (I suspect it's a 3-clock delay in starting, not a 3-clock into
the future affair)
Probably only going to be able to get the timers working without heroic
amounts of effort.
MUL timing is fixed to use idle cycles.
STMIA is fixed to set sequential at the right moments.
DMA priority support is added, so DMA 0 can interrupt DMA 1 mid-transfer.
In other news ...
I'm calling gtk_widget_destroy on the GtkWindow now, so hopefully those
Window_configure issues go away.
I realize I was leaking Display* handles in the X-video driver while
I was looking at it, so I fixed those.
I added DT_NOPREFIX so the Windows ListView will show & characters
correctly now.
byuu says:
Note: for Windows users, please go to nall/intrinsics.hpp line 60 and
correct the typo from "DISPLAY_WINDOW" to "DISPLAY_WINDOWS" before
compiling, otherwise things won't work at all.
This will be a really major WIP for the core SNES emulation, so please
test as thoroughly as possible.
I rewrote the 65816 CPU core's dispatcher from a jump table to a switch
table. This was so that I could pass class variables as parameters to
opcodes without crazy theatrics.
With that, I killed the regs.r[N] stuff, the flag_t operator|=, &=, ^=
stuff, and all of the template versions of opcodes.
I also removed some stupid pointless flag tests in xcn and pflag that
would always be true.
I sure hope that AWJ is happy with this; because this change was so that
my flag assignments and branch tests won't need to build regs.P into
a full 8-bit variable anymore.
It does of course incur a slight performance hit when you pass in
variables by-value to functions, but it should help with binary size
(and thus cache) by reducing a lot of extra functions. (I know I could
have used template parameters for some things even with a switch table,
but chose not to for the aforementioned reasons.)
Overall, it's about a ~1% speedup from the previous build. The CPU core
instructions were never a bottleneck, but I did want to fix the P flag
building stuff because that really was a dumb mistake v_v'
byuu says:
This WIP substantially restructures the ruby API for the first time
since that project started.
It is my hope that with this restructuring, destruction of the ruby
objects should now be deterministic, which should fix the crashing on
closing the emulator on Linux. We'll see I guess ... either way, it
removed two layers of wrappers from ruby, so it's a pretty nice code
cleanup.
It won't compile on Windows due to a few issues I didn't see until
uploading the WIP, too lazy to upload another. But I fixed all the
compilation issues locally, so it'll work on Windows again with the next
WIP (unless I break something else.)
(Kind of annoying that Linux defines glActiveTexture but Windows
doesn't.)
byuu says:
Added AWJ's fixes for alt/cpu (Tetris Attack framelines issue) and
alt/dsp (Thread::clock reset)
Added fix so that the taskbar entry appears when the application first
starts on Windows.
Fixed checkbox toggling inside of list views on Windows.
Updated nall/image to properly protect variables that should not be
written externally.
New Object syntax for hiro is in.
Fixed the backwards-typing on Windows with the state manager.
NOTE: the list view isn't redrawing when you change the description
text. It does so on the cheat editor because of the resizeColumns call;
but that shouldn't be necessary. I'll try and fix this for the next WIP.
byuu says:
Obviously, this is a fairly major WIP. It's the first public release in
17 months. The entire UI has been rewritten (for the 74th time), and is
now internally called tomoko. The official releases will be named higan
(both the binaries and title bar.)
Missing features from v094:
- ananke is missing (this means you will need v094 to create game
folders to be loaded)
- key assignments are limited to one physical button = one mapping (no
multi-mapping)
- shader support is missing
- audio/video profiling is missing
- DIP switch window is missing (used by NSS Actraiser with a special
manifest; that's about it)
- alternate paths for game system folders and configuration BML files
There's some new stuff, but not much. This isn't going to be an exciting
WIP in terms of features. It's more about being a brand new release with
the brand new hiro port and its shared memory model. The goal is to get
these WIPs stable, get v095 out, and then finally start improving the
actual emulation again after that.
byuu says:
Windows port should run mostly well now, although exiting fullscreen
breaks the application in a really bizarre way. (clicking on the window
makes it sink to background rather than come to the foreground o_O)
I also need to add the doModalChange => audio.clear() thing for the
accursed menu stuttering with DirectSound.
I also finished porting all of the ruby drivers over to the newer API
changes from nall.
Since I can't compile the Linux or OS X drivers, I have no idea if there
are any typos that will result in compilation errors. If so, please let
me know where they're at and I'll try and fix them. If they're simple,
please try and fix them on your end to test further if you can.
I'm hopeful the udev crash will be gone now that nall::string checks for
null char* values passed to its stringify function. Of course, it's
a problem it's getting a null value in the first place, so it may not
work at all.
If you can compile on Linux (or by some miracle, OS X), please test each
video/audio/input driver if you don't mind, to make sure there's no
"compiles okay but still typos exist" bugs.
byuu says:
Finally!! Compilation works once again on Windows.
However, it's pretty buggy. Modality isn't really working right, you can
still poke at other windows, but when you select ListView items, they
redraw as empty boxes (need to process WM_DRAWITEM before checking
modality.)
The program crashes when you close it (probably a ruby driver's term()
function, that's what it usually is.)
The Layout::setEnabled(false) call isn't working right, so you get that
annoying chiming sound and cursor movement when mapping keyboard keys to
game inputs.
The column sizing seems off a bit on first display for the Hotkeys tab.
And probably lots more.
byuu says:
The library window is gone, and replaced with
hiro::BrowserWindow::openFolder(). This gives navigation capabilities to
game loading, and it also completes our slotted cart selection code. As
an added bonus, it's less code this way, too.
I also set the window size to consistent sizes between all emulated
systems, so that switching between SFC and GB don't cause the window
size to keep changing, and so that the scaling size is consistent (eg at
normal scale, GB @ 3x is closer to SNES @ 2x.) This means black borders
in GB/GBA mode, but it doesn't look that bad, and it's not like many
people ever use these modes anyway.
Finally, added the placeholder tabs for video, audio and timing. I don't
intend to add the timing calculator code to v095 (it might be better as
a separate tool), but I'll add the ability to set video/audio rates, at
least.
Glitch 1: despite selecting the first item in the BrowserDialog list, if
you press enter when the window appears, it doesn't activate the item
until you press an arrow key first.
Glitch 2: in Game Boy mode, if you set the 4x window size, it's not
honoring the full requested height because the viewport is smaller than
the window. 8+ years of trying to get GTK+ and Qt to simply set the god
damned window size I ask for, and I still can't get them to do it
reliably.
Remaining issues:
- finish configuration panels (video, audio, timing)
- fix ruby driver compilation on Windows
- add DIP switch selection window (NSS) [I may end up punting this one
to v096]
byuu says:
I fixed the hiro layout enable bug, so when you go to assign joypad
input, the window disables itself so your input doesn't mess with the
controls.
I added "reset" to the hotkeys, in case you feel like clearing all of
them at once.
I added device selection support and the ability to disable audio
synchronization (run > 60fps) to the ruby/OSS driver. This is exposed in
tomoko's configuration file.
I added checks to stringify so that assigning null char* strings to
nall::string won't cause crashes anymore (technically the crash was in
strlen(), which doesn't check for null strings, but whatever ... I'll do
the check myself.)
I hooked up BrowserDialog::folderSelect() to loading slotted media for
now. Tested it by loading a Game Boy game successfully through the Super
Game Boy. Definitely want to write a custom window for this though, that
looks more like the library dialog.
Remaining issues:
- finish slotted cart loader (SGB, BSX, ST)
- add DIP switch selection window (NSS) [I may end up punting this one
to v096]
- add more configuration panels (video, audio, timing)
byuu says:
Main reason for this WIP was because of all the added lines to hiro for
selective component disabling. May as well get all the diff-noise apart
from code changes.
It also merges something I've been talking to Cydrak about ... making
nall::string::(integer,decimal) do built-in binary,octal,hex decoding
instead of just failing on those. This will have fun little side effects
all over the place, like being able to view a topic on my forum via
"forum.byuu.org/topic/0b10010110", heh.
There are two small changes to higan itself, though. First up, I fixed
the resampler ratio when loading non-SNES games. Tested and I can play
Game Boy games fine now. Second, I hooked up menu option hiding for
reset and controller selection. Right now, this works like higan v094,
but I'm thinking I might want to show the "Device -> Controller" even if
that's all that's there. It kind of jives nicer with the input settings
window to see the labels there, I think. And if we ever do add more
stuff, it'll be nice that people already always expect that menu there.
Remaining issues:
* add slotted cart loader (SGB, BSX, ST)
* add DIP switch selection window (NSS)
* add timing configuration (video/audio sync)
byuu says:
Implemented the cheat database dialog, and most of the cheat editor
dialog. I still have to handle loading and saving the cheats.bml file
for each game. I wanted to finish it today, but I burned out. It's a ton
of really annoying work to support cheat codes. There's also some issue
with the width calculation for the "code(s)" column in hiro/GTK.
Short-term:
- add input port changing support
- add other input types (mouse-based, etc)
- finish cheat codes
Long-term:
- add slotted cart loader (SGB, BSX, ST)
- add DIP switch selection window (NSS)
- add overscan masking
- add timing configuration (video/audio sync)
Not planned:
- video color adjustments (will allow emulated color vs raw color; but
no more sliders)
- pixel shaders
- ananke integration (will need to make a command-line version to get my
games in)
- fancy audio adjustment controls (resampler, latency, volume)
- input focus settings
- localization support (not enough users)
- window geometry memory
- anything else not in higan v094
byuu says:
This version polishes up the input dialogue (reset, erase, disable
button when item not focused, split device ID from mapping name), adds
color emulation toggle, and add dummy menu items for remaining features
(to be filled in later.)
Also, it now compiles cleanly on Windows with GTK.
I didn't test with TDM-GCC-32, because for god knows what reason, the
32-bit version ships with headers from Windows 95 OSR2 only. So I built
with TDM-GCC-64 with arch=x86.
And uh, apparently, moving or resizing a window causes a Visual C++
runtime exception in the GTK+ DLLs. This doesn't happen with trance or
renshuu built with TDM-GCC-32. So, yeah, like I said, don't use -m32.

Changelog:
* added driver selection
* added video scale + aspect correction settings
* added A/V sync + audio mute settings
* added configuration file
* fixed compilation bugs under Windows and Linux
* fixed window sizing
* removed HSU1
* the system menu stays as "System", because "Game Boy Advance" was too
long a string for the smallest scale size
* some more stuff
You guys probably won't be ecstatic about the video sizing options, but
it's basically your choice of 1x, 2x or 4x scale with optional aspect
correction. 3x was intentionally skipped because it looks horrible on
hires SNES games. The window is resized and recentered upon loading
games. The window doesn't resize otherwise. I never really liked the way
v094 always left you with black screen areas and left you with
off-centered window positions.
I might go ahead and add the pseudo-fullscreen toggle that will jump
into 4x mode (respecting your aspect setting.)
Short-term:
* add input port changing support
* add other input types (mouse-based, etc)
* add save states
* add cheat codes
* add timing configuration (video/audio sync)
* add hotkeys (single state)
We can probably do a new release once the short-term items are
completed.
Long-term:
* add slotted cart loader (SGB, BSX, ST)
* add DIP switch selection window (NSS)
* add cheat code database
* add state manager
* add overscan masking
Not planned:
* video color adjustments (will allow emulated color vs raw color; but
no more sliders)
* pixel shaders
* ananke integration (will need to make a command-line version to get my
games in)
* fancy audio adjustment controls (resampler, latency, volume)
* input focus settings
* relocating game library (not hard, just don't feel like it)
* localization support (not enough users)
* window geometry memory
* anything else not in higan v094
byuu says:
I've hooked up the input subsystem, and the input manager to assign
hotkeys.
So far I only have digital buttons working (keyboard only), and I'm not
planning on supporting input groups again (mapping multiple physical
buttons to one emulated button), but it's progress. As with the rest of
tomoko, the code's a lot more compact. The nice thing about redoing code
so many times is that each time you get a little bit better at it.
The input configuration is saved to ~/.config/tomoko/settings.bml (just
realized that I'm an idiot and need to rename it to input.bml)
Also hooked up game saves and cartridge unloading. Active controller
changing isn't hooked up yet, and I'll probably do it differently.
Oh, and I declared the ruby lines for other platforms.
Still need to add Cydrak's Windows compilation fixes. I am nothing if
not lazy :P
byuu says:
This will easily be the biggest diff in the history of higan. And not in
a good way.
* target-higan and target-loki have been blown away completely
* nall and ruby massively updated
* phoenix replaced with hiro (pretty near a total rewrite)
* target-higan restarted using hiro (just a window for now)
* all emulation cores updated to compile again
* installation changed to not require root privileges (installs locally)
For the foreseeable future (maybe even permanently?), the new higan UI
will only build under Linux/BSD with GTK+ 2.20+. Probably the most
likely route for Windows/OS X will be to try and figure out how to build
hiro/GTK on those platforms, as awful as that would be. The other
alternative would be to produce new UIs for those platforms ... which
would actually be a good opportunity to make something much more user
friendly.
Being that I just started on this a few hours ago, that means that for
at least a few weeks, don't expect to be able to actually play any
games. Right now, you can pretty much just compile the binary and that's
it. It's quite possible that some nall changes didn't produce
compilation errors, but will produce runtime errors. So until the UI can
actually load games, we won't know if anything is broken. But we should
mostly be okay. It was mostly just trim<1> -> trim changes, moving to
Hash::SHA256 (much cleaner), and patching some reckless memory copy
functions enough to compile.
Progress isn't going to be like it was before: I'm now dividing my time
much thinner between studying and other hobbies.
My aim this time is not to produce a binary for everyone to play games
on. Rather, it's to keep the emulator alive. I want to be able to apply
critical patches again. And I would also like the base of the emulator
to live on, for use in other emulator frontends that utilize higan.
