gm-matthew b2fee4242c DMA device register always returns Step 1.x PCI ID
Step 2.x games by AM3 request PCI ID this way and expect to see 0x16c311db

gm-matthew 015e8e9212 Drive board uses the value 0xFF (not 0x00) on ports 42 and 45 to stop all effects when port 46 is set to 0xFF; fixes FFB effects continuing after game ends 2023-07-01 23:21:51 -07:00

gm-matthew 2063303a4d Wait until IRQ2 is acknowledged before starting IRQ40 sequence. Fixes Ski Champ hanging at FBI screen when region set to USA 2022-11-25 15:27:12 -08:00
gm-matthew 79a2414f3f Incomplete texture headers uploaded via FIFO are now discarded. Ski Champ sends one more 32-bit word via DMA than it should which was causing Supermodel to erroneously intepret the extra word as another texture 2022-11-19 21:06:39 -08:00
toxieainc 4c727abdc8 change all INT16 mixing/intermediate clamping to floats
also fixes 3 bugs:
1) mpeg right channel volume was always using the left channel volume, too
2) too high MusicVolume setting was not clamped to 0..200
3) too high SoundVolume setting was not clamped to 0..200

toxieainc b98be0c2e7 optimize ReadRegister, as localtime (at least on MSVC/Windows) is significantly showing up in profiling
e.g. in SW Trilogy

caches localtime until time changes (i.e. limits calls to 1/sec)

Bart Trzynadlowski 3f6937e1a6 When dumping textures, two T1RGB5 texture maps are written: with and without contour processing. Contour processing can be disabled per-polygon and some textures intended to be used without contour processing contain pixels with T=1 that are clearly not supposed to be transparent. We now output textures_t1rgb5_contour.bmp and textures_t1rgb5_opaque.bmp. 2022-02-05 00:52:34 +00:00
Bart Trzynadlowski 32933ef9b0 Added a -dump-textures option (config key DumpTextures) that writes texture BMP files, one for each known format (12 in all currently) 2022-02-01 23:15:06 +00:00
Matthew Daniels 646b46fd4b Adjust the number of PowerPC cycles executed per frame to assume 57.524 Hz refresh rate
Fighting Vipers 2 attract mode no longer requires 100+ MHz to run smoothly

Supermodel itself still runs at 60 Hz

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 50465f9a5a Shared RAM on simulated netboard is now double-buffered; Spikeout Final Edition no longer requires a hack to work.

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 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 ?).
