Matthew Daniels 6ff099b5ba Clear all Real3D DMA registers on reset; uninitialized values were causing issues with MSVC debug builds 2021-12-17 23:36:54 +00:00
Matthew Daniels 94772ae3d9 Include required header files in Model3GraphicsState.h - fixes potential build errors in GCC 2021-12-15 13:55:27 +00:00
Matthew Daniels 0c47ac831a Increase MIDI FIFO buffer size for SCSP; should prevent FIFO overflows
Also use similar macro for DSB FIFO buffer

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.

Matthew Daniels 5a570ce7fe Adding simulated netboard; all linked games except Sega Rally 2 working at full speed. 2021-04-14 01:20:45 +00:00
Matthew Daniels 98d4f1c6f6 Corrected alignment issues with netboard RAM; send/receive parameters no longer need to be manipulated to work correctly. Fixes bugs including Scud Race linked car orientation. 2021-03-22 01:08:45 +00:00
SpinDizzy 020e2d1b32 DSB2 clock speed from 4MHz to 11MHz. 2021-03-13 08:17:11 +00:00
SpinDizzy de470aaf52 Fixed cycle counting overflow that was causing DSB2 to halt execution. 2021-03-07 10:12:37 +00:00
Ian Curtis 6cf9974102 missing header 2021-03-03 20:31:57 +00:00
SpinDizzy 46b1de2238 DSB2 IRQ 2 now fires at 1KHz rather than once per frame, improving
music timing in Daytona USA 2 and Sega Rally 2. DSB1 CPU timing 
increased from 1MHz to 4MHz, improving music fade timing in Scud Race. 
Thanks to gm_matthew for these discoveries.

SpinDizzy e4998f57fd Skichamp Driveboard error fix. 2021-02-18 10:35:38 +00:00
SpinDizzy 08d4735ee8 Huge refactor of the Driveboard:
-Separate each possible boards (wheel, joystick, skipad, billboard).
-Defined a Driveboard type in Games.xml for each games.
-Due to the refactoring, Driveboard Savestates have changed (a common base data + a specific board data are saved).
-Backwards compatibility with previous save states is maintained.
-Driveboard rom section is no longer required anymore. This disables Driveboard emulation in case the rom is not found.
-Added Billboard emulation (vf3, vs2, fvipers2, von2). 7 segments and lamps Outputs are redirected to Supermodel outputs.
-Changes project to C++ 17 standard.

SpinDizzy 6627b1e95f The controls of bass/getbass games were no longer good, following recent rom set name changes in Games.xml. 2021-01-05 14:24:57 +00:00
SpinDizzy 6626afc8bb Added rumble skipad in Ski Champ game.
This is only a simulation (cmd are interpreted), not an emulation because we lack informations on the game itself and its driveboard (does it have dedicated cpu/rom ?).

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
Ian Curtis 8aa476aeeb Previous mpeg audio code worked for me in debug mode, but the release build had some serious corruption issues when being built in visual studio. Replaced the old spaghetti code with a more modern implementation. 2019-02-21 14:56:25 +00:00

Ian Curtis 90faeafbc4 Fix the audio in sega rally2. The game has packed separate tracks into the left and right audio channels. Selecting the correct track fixes the garbled mess. (Spindizzi) 2019-02-01 21:02:02 +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 bf4d725970 Smooth texture repeat makes no sense for alpha/contour textures with pixel dilate. HW seems to treat them as non smooth anyway. Also implement some line of sight stuff, used by Scud. Really need to check the threading/synchronisation of the register reads but it basically works. 2018-10-19 20:59:46 +00:00
