r13 and r14 weren't posted as individual releases, but their changelogs
were posted.
byuu says about r13:
I'm not going to be posting WIPs for r13 and above for a while.
The reason is that I'm working on the major manifest overhaul I've
discussed previously on the icarus subforum.
I'm recreating my boards database from scratch using the map files
and the new map analyzer. The only games that will load are ones
I've created board definitions for, and updated
sfc/cartridge/markup.cpp to parse. Once I've finished all the
boards, then I'll update the heuristics.
Then finally, I'll sync the syntax changes over to the fc, gb, gba
cores.
Once that's done, I'll start posting WIPs again, along with a new
build of icarus.
But I'll still post changelogs as I work through things.
Changelog (r13):
- preservation: created new database-builder tool (merges
region-specific databases with boards)
- icarus: support new, external database format
(~/.config/icarus/Database/(Super Famicom.bml, ...)
- added 1A3B-(10,11,12); 1A3B-20
byuu says about r14:
r14 work:
I successfully created mappings for every board used in the US set.
I also updated icarus' heuristics to use the new mappings, and
created ones there for the boards that are only in the JP set.
Then I patched icarus to support pulling games out of the database
when it's used on a game folder to generate a manifest file.
Then I updated a lot of code in higan/sfc to support the new mapping
syntax. sfc/cartridge/markup.cpp is about half the size it used to
be with the new mappings, and I was able to kill off both map/id and
map/select entirely.
Then I updated all four emulated systems (and both subsystems) to
use "board" as the root node, and harmonized their syntax (made them
all more consistent with each other.)
Then I added a manifest viewer to the tools window+menu. It's kind
of an advanced user feature, but oh well. No reason to coddle people
when the feature is very useful for developers. The viewer will show
all manifests in order when you load multi-cart games as well.
Still not going to call any syntax 100% done right now, but
thankfully with the new manifest-free folders, nobody will have to
do anything to use the new format. Just download the new version and
go.
The Super Famicom Event stuff is currently broken (CC92/PF94
boards). That's gonna be fun to support.
byuu says about r15:
EDIT: small bug in icarus with heuristics. Edit
core/super-famicom.cpp line 27:
if(/*auto*/ markup = cartridge.markup) {
Gotta remove that "auto" so that it returns valid markup.
Resolved the final concerns I had with the new manifest format.
Right now there are two things that are definitely broken: MCC (BS-X
Town cart) and Event (CC '92 and PF'94).
And there are a few things that are untested: SPC7110, EpsonRTC,
SharpRTC, SDD1+RAM, SufamiTurbo, BS-X slotted carts.
byuu says:
Changelog:
- all of fc/ ported to "auto function() -> return;" syntax
- (includes all of cartridge/board and cartridge/chip as well; even
though they're all deprecated)
- sfc balanced profile ported to "auto function() -> return;" syntax
- sfc balanced and performance profiles compile again
- Linux always gets -ldl
- removed arch=x86 logic from nall/GNUmakefile, as TDM/GCC64 can't
produce bug-free 32-bit binaries anyway
The only code that continues to use the old function syntax is the SFC
performance core, obscure parts of nall that higan doesn't use, and the
pieces of code that weren't written by me (blargg's SFC-DSP, Ryphecha's
sinc resampler, and OV2's xaudio2 header file.)
I was too burned out to finish it tonight. The above was about four
hours straight of non-stop typing. Really can't wait to be done with
this once and for all.
byuu says:
Changelog:
- fixed I/O register reads; perfect score on endrift's I/O tests now
- fixed mouse capture clipping on Windows [Cydrak]
- several hours of code maintenance work done on the SFC core
All higan/sfc files should now use the auto fn() -> ret; syntax. Haven't
converted all unsigned->uint yet. Also, probably won't do sfc/alt as
that's mostly just speed hack stuff.
Errata:
- forgot auto& instead of just auto on SuperFamicom::Video::draw_cursor,
which makes Super Scope / Justifier crash. Will be fixed in the next
WIP.
Changelog:
- S-SMP core code style updated
- S-SMP loads reset vector from IPLROM ($fffe-ffff)
- sfc/base => sfc/expansion
- system/input => system/device
- added expansion/eBoot (simulation of defparam's SNES-Boot device)
- expansion port device can now be selected from Super Famicom menu
option
- improved GBA MROM/SRAM reading
endrift's memory test is up to 1388/1552.
Note: I added the expansion port devices to the same group as controller
ports. I also had to move "None" to the top of the list. Before v096,
I am going to have to add caching of port selections to the
configuration file, check the proper default item in the system menu,
and remove the items with no mappings from the input configuration
window. Lots of work >_>
byuu says:
Changelog:
- SNES mid-scanline BGMODE fixes finally merged (can run
atx2.zip{mode7.smc}+mtest(2).sfc properly now)
- Makefile now discards all built-in rules and variables
- switch on bool warning disabled for GCC now as well (was already
disabled for Clang)
- when loading a game, if any required files are missing, display
a warning message box (manifest.bml, program.rom, bios.rom, etc)
- when loading a game (or a game slot), if manifest.bml is missing, it
will invoke icarus to try and generate it
- if that fails (icarus is missing or the folder is bad), you will get
a warning telling you that the manifest can't be loaded
The warning prompt on missing files work for both games and the .sys
folders and their files. For some reason, failing to load the DMG/CGB
BIOS is causing a crash before I can display the modal dialog. I have no
idea why, and the stack frame backtrace is junk.
I also can't seem to abort the failed loading process. If I call
Program::unloadMedia(), I get a nasty segfault. Again with a really
nasty stack trace. So for now, it'll just end up sitting there emulating
an empty ROM (solid black screen.) In time, I'd like to fix that too.
Lastly, I need a better method than popen for Windows. popen is kind of
ugly and flashes a console window for a brief second even if the
application launched is linked with -mwindows. Not sure if there even is
one (I need to read the stdout result, so CreateProcess may not work
unless I do something nasty like "> %tmp%/temp") I'm also using the
regular popen instead of _wpopen, so for this WIP, it won't work if your
game folder has non-English letters in the path.
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:
Okay yeah, lots of SNES coprocessor games were horribly broken. They
should be fixed now with the below changes:
Old syntax:
auto programROM = root["rom[0]/name"].text();
auto dataROM = root["rom[1]/name"].text();
load_memory(root["ram[0]"]);
New syntax:
auto rom = root.find("rom");
auto ram = root.find("ram");
auto programROM = rom(0)["name"].text();
auto dataROM = rom(1)["name"].text();
load_memory(ram(0));
Since I'm now relying on the XShm driver, which is multi-threaded, I'm
now compiling higan with -fopenmp. On FreeBSD, this requires linking
with -Wl,-rpath=/usr/local/lib -Wl,-rpath=/usr/local/lib/gcc49 to get
the right version of GOMP.
This gives a pretty nice speed boost for XShm, I go from around 101fps
to 111fps at 4x scale on the accuracy profile. The combination of
inlining the accuracy-PPU and parallelizing the XShm renderer about
evenly compensates now for the ~20% CPU overclock I gave up a while ago.
The WIP also has some other niceties from the newer version of nall.
Most noticeably, cheat code database searching is now instantaneous. No
more 3-second stall.
byuu says:
This updates higan to use the new Markup::Node changes. This is a really
big change, and one slight typo anywhere could break certain classes of
games from playing.
I don't have ananke hooked up again yet, so I don't have the ability to
test this much. If anyone with some v094 game folders wouldn't mind
testing, I'd help out a great deal.
I'm most concerned about testing one of each SNES special chip game.
Most notably, systems like the SA-1, HitachiDSP and NEC-DSP were using
the fancier lookups, eg node["rom[0]/name"], which I had to convert to
a rather ugly node["rom"].at(0)["name"], which I'm fairly confident
won't work. I'm going to blame that on the fumes from the shelves I just
stained >.> Might work with node.find("rom[0]/name")(0) though ...? But
so ugly ... ugh.
That aside, this WIP adds the accuracy-PPU inlining, so the accuracy
profile should run around 7.5% faster than before.
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.
byuu says:
New terminal is in. Much nicer to use now. Command history makes a major
difference in usability.
The SMP is now fully traceable and debuggable. Basically they act as
separate entities, you can trace both at the same time, but for the most
part running and stepping is performed on the chip you select.
I'm going to put off CPU+SMP interleave support for a while. I don't
actually think it'll be too hard. Will get trickier if/when we support
coprocessor debugging.
Remaining tasks:
- aliases
- hotkeys
- save states
- window geometry
Basically, the debugger's done. Just have to add the UI fluff.
I also removed tracing/memory export from higan. It was always meant to
be temporary until the debugger was remade.
byuu says:
This WIP removes nall/input.hpp entirely, and implements the new
universal cheat format for FC/SFC/GB/GBC/SGB.
GBA is going to be tricky since there's some consternation around
byte/word/dword overrides.
It's also not immediately obvious to me how to implement the code search
in logarithmic time, due to the optional compare value.
Lastly, the cheat values inside cheats.bml seem to be broken for the
SFC. Likely there's a bug somewhere in the conversion process. Obviously
I'll have to fix that before v094.
I received no feedback on the universal cheat format. If nobody adds
anything before v094, then I don't want to hear any complaining about
the formatting :P
byuu says:
Changelog:
- GBA: SOUND_CTL_H is readable, fixes sound effects in Mario&Luigi
Superstar Saga [Cydrak] (note: game is still unplayable due to other
bugs)
- phoenix/Windows: workaround for Win32 API ListView bug, fixes slot
loading behavior
- ruby: added udev driver for Linux with rumble support, and added
rumble support to existing RawInput driver for XInput and DirectInput
- ethos: added new "Rumble" mapping to GBA input assignment, use it to
tell higan which controller to rumble (clear it to disable rumble)
- GBA: Game Boy Player rumble is now fully emulated
- core: added new normalized raw-color palette mode for Display
Emulation shaders
The way rumble was added to ethos was somewhat hackish. The support
doesn't really exist in nall.
I need to redesign the entire input system, but that's not a change
I want to make so close to a release.
byuu says:
Changelog:
- Game Boy (Color): STAT OAM+HBlank IRQs only trigger during LY=0-143
with display enabled
- fixes backgrounds and text in Wacky Races
- Game Boy (Color): fixed underflow in window clamping
- fixes Wacky Races, Prehistorik Man, Alleyway, etc
- Game Boy (Color): LCD OAM DMA was running too slow
- fixes Shin Megami Tensei - Devichil - Kuro no Sho
- Game Boy Advance: removed built-in frame blending; display emulation
shaders will handle this going forward
- Game Boy Advance: added Game Boy Player emulation
- currently the screen is tinted red during rumble, no actual gamepad
rumble support yet
- this is going to be slow, as we have to hash the frame to detect the
GBP logo, it'll be optional later on
- Emulator::Interface::Palette can now output a raw palette (for Display
Emulation shaders only)
- color channels are not yet split up, it's just the raw packed value
byuu says:
Changelog:
- Windows port should compile out-of-the-box
- InputManager::scancode[] initialized at startup
- Library menu shows item for each bootable media type (notably Game Boy
Color)
- Display Emulation menu selection fix
- LibraryManager load button works now
- Added hotkey to show library manager (defaults to L)
- Added color emulation to video settings (missing on GBA for now)
- SFC loading SGB without GB cartridge no longer segfaults
- GB/GBC system.load() after cartridge.load()
- GB/GBC BG-over-OAM fix
- GB/GBC disallow up+down and left+right
byuu says:
Changelog:
- added Cocoa target: higan can now be compiled for OS X Lion
[Cydrak, byuu]
- SNES/accuracy profile hires color blending improvements - fixes
Marvelous text [AWJ]
- fixed a slight bug in SNES/SA-1 VBR support caused by a typo
- added support for multi-pass shaders that can load external textures
(requires OpenGL 3.2+)
- added game library path (used by ananke->Import Game) to
Settings->Advanced
- system profiles, shaders and cheats database can be stored in "all
users" shared folders now (eg /usr/share on Linux)
- all configuration files are in BML format now, instead of XML (much
easier to read and edit this way)
- main window supports drag-and-drop of game folders (but not game files
/ ZIP archives)
- audio buffer clears when entering a modal loop on Windows (prevents
audio repetition with DirectSound driver)
- a substantial amount of code clean-up (probably the biggest
refactoring to date)
One highly desired target for this release was to default to the optimal
drivers instead of the safest drivers, but because AMD drivers don't
seem to like my OpenGL 3.2 driver, I've decided to postpone that. AMD
has too big a market share. Hopefully with v093 officially released, we
can get some public input on what AMD doesn't like.
