Ian Curtis e1827cfd13 Stretch the time the ping_pong bit flips a bit to bump writes into correct frame. Otherwise they end up getting written at like 99.8% of the frame and overlapping with the next. 2019-11-08 20:36:11 +00:00
Ian Curtis 2e6968fe9d Thanks to our anonymous contributor who managed to patch a model 3 game and run it on real h/w, we were able to obtain some timing values we had been long been missing for correct emulation. The h/w polls something called the ping_pong bit at start-up to sync the GPU with the CPU. Unfortunately we didn't have the correct values and just manually used some per game hacks to get games to run. This mostly worked, but some games were writing more or less frames than they should have been for a given time period. When the ping_pong bit flips at 66% of the frame time, games were writing data for a new frame, which meant writes were often straddling 2 separate frames. We aren't 100% sure if IRQ2 or the ping_pong bit is vblank. 2019-11-07 20:29:17 +00:00
SpinDizzy b0813ef7a0 - PCI bridge can be specified in Games.xml for games that use a different version than expected based on stepping. No more hard-coded exceptions.
- Real3D PCI ID can be specified in Games.xml for exceptions that require it.
- Real3D status bit timing specified in Games.xml for exceptions that require it.

Ian Curtis 0b6da91cc0 add the rest of the network board code (Spindizzi) 2018-01-07 14:07:59 +00:00
Bart Trzynadlowski 55bb02d4e5 - New work-in-progress frame timing code (disabled by default, compile with NEW_FRAME_TIMING defined to activate it)
- New JTAG emulation, moved into its own class, CJTAG
- Removed game-specific sun clamp hacks from CNew3D (JTAG and Real3D emulation will call the appropriate method to configure this at run-time)
- Removed JTAG from Real3D save state data and reused some of that space for new state variables having to do with the internal JTAG-based config as well as new frame timing state variables

Bart Trzynadlowski f04a285727 DMA and register space access for Real3D have been unified and CReal3D::ReadRegister() returns little endian data now that the PowerPC handler byte-swaps back, to be consistent with how DMA registers work. 2017-08-29 01:28:21 +00:00

Ian Curtis 5709ee2659 Sometime ago I managed to work out that specular on the model3 is not real specular, and really is just an extension of diffuse lighting. But attempts were derailed by corner cases and the fact we were not handling the normals correctly. Anyway Harry managed to successfully come up with an algorithm, and coefficients that give an almost perfect match to specular on the model3, based soley on observations from video footage! He also worked out that the lighting on hardware 1.5 onwards appears to be unclamped (ie greater than 1). This quite radically changes the brightness of some of the games, but much better matches the original hardware. 2017-08-09 16:56:56 +00:00
Bart Trzynadlowski a649a0d36b Removed patches from source code and moved them into game XML file. Created ROMSet.cpp. Print a more descriptive error when game XML file fails to load. 2017-04-08 18:30:29 +00:00
Bart Trzynadlowski 4ca7d5ef0e Harry Tuttle's change to Harley gear shift to use a single bit instead of two (no detectable difference in behavior, though) 2017-04-07 04:30:27 +00:00
Bart Trzynadlowski c013eab711 Changes by Harry Tuttle: game list more accurately reflects MAME's, added a root level XML "games" node, print ROM version along with title 2017-04-05 05:35:45 +00:00
Bart Trzynadlowski f34e25dfc7 Massive internal change: removed CConfig object and replaced it with a hierarchical config object system (Util::Config::Node). Games are now defined in an XML file. Hopefully I didn't break too many things :/ 2017-03-27 03:19:15 +00:00
Bart Trzynadlowski 61159c07f8 Added 8- and 16-bit tilegen VRAM access handlers to fix missing columns in Star Wars Trilogy tilemaps. Thanks to Spindizzi for initial confirmation that this was the problem. 2017-03-23 04:22:25 +00:00

Ian Curtis d2563c035f you were right Bart :) (Fixes broken sound in last build) 2016-04-11 15:16:35 +00:00
Bart Trzynadlowski 775256118d Fixed Magical Truck Adventure country check (accidentally removed a line in previous commit). 2016-04-10 23:57:55 +00:00
Bart Trzynadlowski 7ade3a6abb Magical Truck Adventure expects 0x03 to be returned from MIDI control port (thanks, Ville). Game now boots but crashes because VROM texture uploads clobber memory for some reason. 2016-04-10 21:47:07 +00:00

Nik Henson 8835d6fe36 Some updates to Supermodel made at beginning of the year but only now got around to checking in (better late than never...):
- hooked up the remaining controls in Supermodel (except for Magical Truck Adventure which does not work at all yet).  The new controls are:
  * InputAnalogJoyTrigger2 and InputAnalogJoyEvent2 for the additional second trigger and event buttons that were missing from Star Wars Trilogy,
  * InputRearBrake and InputMusicSelect for the rear brake and music selection buttons that were missing from Harley Davidson,
  * InputAnalogGunXXX, InputAnalogTriggerXXX, InputAnalogGunXXX2 and InputAnalogTriggerXXX2 for the analogue guns of Ocean Hunter and LA Machineguns (NOTE: these controls must be calibrated in the games' service menus otherwise they will not work properly.  Also, the alignment of the gun cursor does not line up very well with the mouse position at the moment, but at least the games are a bit more playable now, although still with numerous graphical glitches...)
  * InputSkiXXX for the controls of Ski Champ, making the game playable now.
- hooked up existing InputViewChange control to Harley Davidson's view change button
- improved the handling of InputGearShiftUp/Down inputs so that they work better with the driving games.  With Dirt Devils, ECA, Harley and LeMans this means they map directly to the game's own shift up/down controls, while with the 4-speed games such as Daytona 2, Scud Racer and Sega Rally 2, they simulate the user shifting up and down through the gears
- added defaults for the new controls to Supermodel.ini
- other small code tweaks:
  * fix small bug with handling of pos/neg inputs mapping to a control with inverted range (0XFF to 0x00) - this was needed to get Ski Champ's X-axis to work properly
  * removed Wait method from InputSystem and added to CThread as CThread::Sleep instead
  * added FrameTimings struct to hold all frame timings in a single place
No networking code yet as just haven't had a chance to work on it since initial progress at the beginning of the year - am *hoping* might have some time to pick it up again over Christmas...

Nik Henson 08d347ccc7 Small tweak to get to compile under GCC (Unix/MacOS) 2012-07-24 20:37:40 +00:00
Nik Henson a3c15e8208 Slight tweak to changes made to sound board synchronisation code in previous commit. The previous change was necessary to ensure no deadlock when waiting for sound board thread to exit but it introduced unwanted buffer overruns (with the end result being that the sound was often speeded up) so have added an extra check in WakeSoundBoardThread to prevent this. 2012-07-24 20:18:30 +00:00
Nik Henson 108ac64de8 - CModel3::StopThreads was rather gracelessly killing threads while they were waiting on their semaphores, which works okay Windows but not on Mac OS-X where it was preventing Supermodel from exiting properly. Hence, have instead altered StopThreads to signal to threads that they should exit and wait until until they have all done so. This is much better and is what I should have done the first time around had I not been so lazy :-)!
- 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.

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...
2012-07-12 06:13:24 +00:00
Bart Trzynadlowski aba801ebb4 Byte swapped sample ROMs. This should fix the audio distortion that many users noticed. The differences are particularly noticeable in Scud Race and Daytona 2. 2012-02-23 03:08:57 +00:00
Nik Henson 8a4ea64994 Added OSD/Video.h to provide OSD-dependent video functionality. The static functions in here get called by Model3.cpp from within the render thread so that any OSD related rendering can also be run in parallel for a further speed increase.
Updated OSD/SDL/Main.cpp to provide the SDL implementations of the functions in OSD/Video.h.
2012-02-13 23:37:48 +00:00
Bart Trzynadlowski 9fc0d7b3cc Updated some comments regarding the VF3 ROM patches. It seems many of them are no longer necessary. The single necessary patch affects timing (note how the warning screen stays up longer when it is removed). This needs to be investigated -- perhaps it can lead to a timing fix for vf3, vs2, and fvipers2? 2012-02-01 18:08:13 +00:00
Nik Henson d1d5175548 New multi-threaded rendering changes that parallelise graphics rendering and PPC execution in order to increase performance on multi-core machines.
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.
