Matthew Daniels e93c5d710f PowerPC IRQ line deassertion; DMA only fires interrupts when required
PowerPC no longer clears its own IRQ line; it is now cleared by the IRQ controller when there are no more pending interrupts. Not all games clear DMA interrupts so it was necessary to tweak the 53C810 SCSI controller and the Real3D DMA interface to only fire interrupts if a certain register is correctly set. 53C810 has the documented DIEN (DMA Interrupt Enable) register; Real3D DMA seems to use the low bit of the dmaConfig register.

Also I removed the net IRQ as no games seem to actually use it.

Matthew Daniels 9ffce8b92a Getting rid of most of the includes from Supermodel.h; each file now explicitly includes the header files it needs.
Making changes to a header file should no longer force the entire project to recompile.

Bart Trzynadlowski 21f813ad3e Fixed a bug in MCRFS instruction related to the VXSOFT, VXSQRT, and VXCVI bits. Thanks to Spindizzi. 2017-08-16 00:58:39 +00:00
Bart Trzynadlowski 198a469ff7 Created IEmulator interface, renamed CBus to IBus and CPCIDevice to IPCIDevice. Frames now rendered when emulator paused. 2016-04-10 03:42:41 +00:00

Nik Henson 183dca563d Committing various small updates that have been hanging around in my source tree for a while now:
- 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

Bart Trzynadlowski 772c94d122 - Committing Nik's timing changes: the PowerPC's DEC and TBR now count at the correct rate and time is accurately maintained between calls to the emulator. A VBlank bit was identified in the Real3D status register space and is now timed. Unfortunately, there are still some problems and not all games are perfect, but FV2, VS2, and others are working much better or perfectly.
- Added a new dump of Scud Race Plus (scudp1). Strangely, this one uses an MPC106 instead of the MPC105 used by every other Step 1.5 game...

Bart Trzynadlowski 79d24d403f - NOTE: In this revision (possibly earlier), I've started to notice some intermittent geometry glitches in Spikeout and slowdown while playing certain characters.
- Added multi-texture fragment shader to repo.
- Added a multiTexture option (enabled by default) to use multi-texturing to decode textures.
- Added some comments regarding timing to the PowerPC execution loop.

Bart Trzynadlowski 46bc52bb12 - Changed save state error messages slightly.
- 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.

Bart Trzynadlowski 2f5bf43bda Updated copyright information and added headers to all remaining files except debugger. 2011-09-14 19:08:43 +00:00
Bart Trzynadlowski 11d1d61bc2 - Removed BOOL and replaced it with native C++ type, bool.
- Removed TRUE and FALSE, changed to 'true' and 'false' keywords.

Bart Trzynadlowski dbc1dbb0e8 - Forgot to add OSDConfig.h.
- Changed more C standard library headers to C++ versions.

Bart Trzynadlowski 12e4d82471 - DSB2 save state support.
- krom made a minor optimization of the byte reverse routines in ppc.cpp.

Bart Trzynadlowski fce3c7ad7c - skichamp now works, but controls are not hooked up and seems to overload the display lists like many non-working Step 2.x games do. To bypass the drive board error, enter the test menu and exit again. It will reboot and run.
- Added some notes on the cause of the "NO DAUGHTER BOARD DETECTED" error in Real3D.cpp.
- Removed some debug code from texture uploader.
