Some old 2D games change palettes very frequently, which causes the
texture to be updated for each render.
This change uses a hash of the palette to detect changes, and include
the palette type in the cache key to distinguish textures of different
depth.
Now it actually says something about what exactly it tries to open, also on "cancel" it exits gracefully.
Proposal: instead of checking one thousand return codes, which are easily ignored, I suggest using an exceptions (this part of emulator doesn't require execution speed, so exceptions here would be just fine).
The VMU which was written to disk was never initialized and therefore consisted only of zeroes.
After saving for the first time the VMU was corrupted.
Changes:
* Not only initialize the VMU in memory but also write the correct contents to disk
* If an existing VMU consists only of zeroes overwrite it with the initial empty VMU

Modified for use w/ reicast per-game configuration
A new function was introduced to abstract the setup of input devices for each os: os_SetupInput().
I hope I implemented this everywhere correctly and the behaviour is identical to before.
The new function mcfg_CreateNAOMIJamma() creates the NAOMI Jamma interface and is hidden behind a compile flag (same as before).
The previous function mcfg_CreateDevices() was renamed to mcfg_CreateDevicesFromConfig() because it creates the devices based on the configuration (``nb`` setting).
Don't expose mcfg_Create() directly, but use a proxy method mcfg_CreateController() to create the complete controller.
Using evdev the ``nb``-setting in the ``emu.cfg`` is no longer necessary (see #970) as the devices get created while initializing the controllers.
Moved the ``switch`` to it's own function.
The SH4 sets the signaling bit to 0 for qNaN: 7fbfffff instead of the
usual 7fffffff. Same games seem to rely on this.
Fixes Fur Fighters freeze and missing geometry in game.
The -ffast-math gcc option implies the -ffinite-math-only option, which
produces wrong results with Inf and NaN. Use integer math to detect the
sign of float numbers in FTRC to avoid these issues.
Also the upper cut off value for conversion was apparently wrong.
Also fixed the x86 dynarec but not tested.
Fixes wrong car color in Tokyo Xtreme Racer car selection screen.
div32 matching doesn't handle division by zero and edge cases, which
causes crashes with some games.
Setting enabled by default for Pro Pinball Trilogy.
Instead of ignoring TA data if ListInit hasn't been called, call
ListInit then accept the data. The data will still be probably ignored
but end of list interrupts are sent so game won't hang.
Fixes hang in King of Fighters New Wave (Naomi).
Some games do not align TA_ISP_BASE on 1 MB boundary so the rendering
context is not found at render time. Fixes black screen in NFL 2K2, NBA
2K2, Oooga Booga, Floigan Bros. and probably more Visual Concepts games.
Sadly Ooga Booga still crashes.
The previous algorithm to determine the sort mode for TR polys was
faulty. And the sort mode can vary between passes for multipass
rendering. This also removes the need for the hack to support Always
depth mode with autosorted TR polys. Should fix the Resident Evil 3 menu
problem.
Parse modifier volumes similarily to other polys (first, count, params).
Draw all triangles in one shot and use quad to sum up instead of
redrawing entire strip. Use OR operation for open volumes/quads
(Soulcalibur).
This allows for some very primitive auto-automated testing, by comparing known good frames.
As this happens on the TA level, it doesn't actually require rendering (and thus it's server friendly)
Two new config entries under the new [testing] namespace control behavior
- ta.HashLogFile, file where data should be logged, empty if not logging
- ta.HashCheckFile, past log to check against, empty if not checking
The emu will crash via verify if the logs don't match, and exit(1) if they do
- Rewrite mem ops to only modify regs after exception path
- Throw & catch logic for interpreter that raises the exception
- Re-enabled some commented mmu code
This adds support for separate config and data dirs.
On Linux, these will be compliant XDG Basedir Specification, i.e.
XDG_CONFIG_HOME and XDG_CONFIG_DIRS (or XDG_DATA_HOME and XDG_DATA_DIRS
respectively). On all other platforms, there currently just set to the
homedir path (so no previous behaviour has been changed).
If reicast wants to read and write a data file, it just calls
get_data_path("/samplefile.txt"). If it does not need to write to
that file, it just uses get_data_path("/samplefile.txt", false). That
way, we can also use system-wide dirs (like /usr/share/reicast on
linux), that the user usually doesn't have write access to.
The same applies for config file, where you use get_config_path(args)
respectively.
Reicast doesn't support exceptions yet, so this isn't of much use now,
and is intended mostly as documentation. nullDC used some call stack
hooking magic to handle exceptions, which was never generic and clean
enough to be worth the effort to port to Reicast.
- Setups state, copies binary
- Binary locks up w/ a reboot loop
Naomi roms have a 512-byte header, executable length seems to be
at 368 or 3C0. The rom is copied from [0, len) to 0x0c020000.The
bios then hands over control at 0x0c021000

This consolidates some of the work done for TARGET_NO_NVMEM and
feat/no-direct-memmap. If nvmem is disabled at compile time or alloc
fails _nvmem_enabled() will return false. Various other fixes
and cleanups all around.
- Import naomi code from nullDC, modify and cleanup
- Only unprotected dimm-board support, custom lst files
- Still a compile option
- Boots naomi bios and some games, no input yet
This required moving the SH4_TCB outside the exe, as new tables that belong on the executable are ignored.
This isn't perfect, but there's a large area to scan for available address space so it shouldn't be a problem
- Basic pixel pipeline, a bit better triangle tests, specialized render handlers
- Textures w/ point filtering. Not very smart is it goes 32 -> 16 -> 32 bpp, but works.
- The texture cache is shared rather inelegantly w/ OpenGL one
- Culling
- PParam sorting (shared w/ GL)
The texturing and color blending paths are ugly and slow
- Adapted for indexed, async rendering, shared ta decoder
- This blits via a quick-and-hacky GDI blitter for now
- SSE/MMX intrins based, so not very portable
- A rather not good "reference" implementation
- At least, it's not terribly slow though
- GetTexture moved to Renderer interface
Using external function pointers is broken after the rec-cpp structural changes,
and relatively low priority so disabled for now.
Fixes builds on arm, non-android (see #720)
Since read_params, packet_cmd, read_buff, pio_buff, ata_cmd, cdda and
ByteCount have not been declared static, they are visible in other
translation units. Since their structs are anonymous, their types have
internal linkage only. Thus, accessing them in other translations units
is impossible anyway.
By declaring them static, we're giving it internal linkage so that
neither the type nor the variable are visible in other translation
units.
