- Also fixed a small race condition in WakeSoundBoardThread. Previously if it happened to be called just before the sound board thread had finished processing a frame's worth of audio but before it had got around to waiting on the sync condition variable then the wake notification would be lost.
- Added 'crosshairs' command line and config option.
- Added 'vsync' command line and config option (so far only tested on NVidia cards on Windows 7 - other graphics drivers, O/Ss or driver settings may simply chose to ignore this).
- Added fullscreen toggle within game using Alt+Enter key combination.
- Added framework for lamp outputs and 'outputs' command line and config option. So far only the lamps for driving games are hooked up in the emulator (others to be added later).
- Added an initial outputs implementation for Windows that sends MAMEHooker compatible messages (-outputs=win to enable)
- Fixed fps calculation in Main.cpp that was producing incorrect results and so giving the impression that frame throttling wasn't working properly when in fact it was.
- Fixed palette indexed colours as the index was always off by one, causing incorrect colours in various games, eg drivers' suits and flashing Start sign in Daytona 2.
- Altered caching of models so that models with palette indexed colours use the dynamic cache rather than the static one. This is so that changes in palette indexed colours appear on screen, eg the flashing Start sign on the advanced course of Daytona 2 (although currently the START message itself is not visible due to other problems with texture decoding).
- Fixed small bug in TileGen.cpp which meant both palettes were being completely recomputed pretty much with every frame. This was a significant performance hit, particularly as palette recomputation is currently being done in SyncSnapshots (it should be moved out of here at some point, although for now it's no big deal).
- Made sure all OpenGL objects and resources are deleted in Render2D/3D destructors, in particular the deleting of the VBO buffer in DestroyModelCache.
- Made sure that GLSL uniforms are always checked to see if they are bound before using them in order to stop unecessary (but harmless) GL errors.
- Altered the default texture sheet handling to use a single large GL texture holding multiple Model3 texture sheets rather than multiple GL textures as before (if required, the old behaviour can still be selected with the mulisheet fragment shader). I believe this fixes the disappearing crosshairs/corrupt GL state problem which the multisheet fragment shader seemed to be triggering somehow.
- Fixed a bug in debugger which meant memory watches were not triggering properly
New gpuMultiThreaded config option to enable/disable multi-threaded rendering (enabled by default, disabling it reverts to previous behaviour).
Other rendering optimisations:
- texture uploads now only affect appropriate region in the texture sheet, rather than uploading the whole sheet each time
- performance of clearing the model caches has been improved
New Alt+O key input added to toggle outputting of frame timings for debugging purposes.
- Added an extra blank line after info display in CModel3.
- Cleaned up comments in Main.cpp.
- More document updates. Fixed '-no-music'->'-no-dsb', 'EmulateMusic'->'EmulateDSB'.
- Wrapped rows that exceed 80 columns in Supermodel.ini.
- Added some member and function comments to a few header files.
- Changed version string to 0.2a-RC2 in anticipation of sending another release candidate build to testers.
- Added GAME_INPUT_RALLY flag to dirtdvlsa, eca, and ecax.
- Configuration dialog no longer refers to Sega Rally 2 and Dirt Devils; instead, "Miscellaneous Driving Game Buttons"
- More additions to README.txt.
- added methods to CModel3 to access sound board and drive board
- added methods to CSoundBoard to access 68K and DSB (if attached)
- added methods to CDSB1 & CDSB2 to access Z80 & 68K respectively
- small code tweak in DriveBoard.cpp
- comment tweaks in Model3.h & Model3.cpp
- fixed bug in SendConstantForce which was sending incorrect values at times
- removed friction effect for now, until can determine its exact command seq
- added checking of compatibility of saved state and temporary disabling of drive board if not compatible
- Fixed an MPEG related crash when loading save states. If usingLoopStart is 0, it is important not to call MPEG_SetLoop()!
- -input-system is working again.
- Changed the format of some messages here and there.
- Moved Logger.h to OSD/, cleaned up comments.
- Command line and config file parsing have been rewritten.
- Began replacing C standard library headers with C++ versions (eg. stdio.h -> cstdio). I think I got most of them, but not all.
- CSoundBoard is not derived from CBus.
- Optimized sound board memory handlers (now using switch statements).
- Added DSB emulation (based on R. Belmont's M1 source code).
- Improved ROM loading: only unique ROMs (those not shared amongst games) are used to identify games. The ROM loader will no longer get confused as easily.
- General cleanup here and there, removed unused Render.h file.
- Added object interface CThread for OSD threading and synchronization, together with SDL implementation
- Added multi-threading to CModel3 so that separate CPUs (PPC of main board, 68K of sound board and Z80 of drive board) can be run in separate threads if requested to improve performance on multi-core PCs
- Added -multi-threaded command line option (default is to run single-threaded still)
- Implemented bank switching for sample ROMs. It is probably incorrect because there is still 2MB of unaccounted-for space.
- Added a few important TO-DO notes.
- Added PPC/68K communication and automatically generated sound IRQs. Sound is now mostly working :)
- Increased SCSP MIDI buffer length to 128 to simulate a large FIFO for PPC->68K commands.
- Added sound ROMs to those games which have 8 MB of sample ROMs.
- Added a 68K interface, CPU/68K/M68K.*.
- Moved Turbo68K source files to CPU/68K/Turbo68K. It is no longer used but is being retained in the source tree for now. The LSR instruction has not been fixed in this update.
- Changed sound board code to use the new 68K interface (and hence, Musashi).
- Changed version string from 0.2-WIP to 0.2a-WIP. This is still an alpha version.
- Above changes have broken the 68K debugger.
- Fixed bug with mapping of multiple assignments.
- Added new ! operator for input mappings, which lets the user specify that an input must not be active.
- Added option to print info about input system (such as settings and detected keyboards, mice and joysticks) during input configuration.
- Added new trigger input for lightgun games with a configurable option to automatically pull trigger when offscreen input is activated (this makes playing with the mouse easier as the gun can be reloaded with single mouse button, rather than having to press both
buttons at the same time).
- Added -xinput command line option that switches to using XInput API rather than DirectInput for XBox 360 controllers (this allows the XBox 360 controller's two triggers to be read independently which works better for driving games when they are mapped to accele
rator and brake).
- Added initial version of force feedback implementation to DirectInputSystem (this still needs work).
