gm-matthew 944e4855d9 Adding newly dumped version of Scud Race
Allow Step 1.5 games to access 53C810 via 0xC00000xx if the netboard is disabled, because scuddxo requires this

Ian Curtis c039d08c03 Add supersampling anti-aliasing
Late christmas present. Due to the way alpha works on the model3 adding regular anti-aliasing doesn't really work. Supersampling is very much a brute force solution, render the scene at a higher resolution and mipmap it.

It's enabled via command line with the -ss option, for example -ss=4 for 4x supersampling or by adding Supersampling = 4 in the config file.

Note non power of two values work as well, so 3 gives a very good balance between speed and quality. 8 will make your GPU bleed, since it is essentially rendering 64 pixels for every visible pixel on the screen.

Matthew Daniels 646b46fd4b Adjust the number of PowerPC cycles executed per frame to assume 57.524 Hz refresh rate

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.

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
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.
