Ian Curtis 6dcf144694 We must explicitly call SDL_SetWindowFullscreen after setting the display mode otherwise the refresh rate doesn't change. 2022-12-24 17:29:08 +00:00
Ian Curtis ad0aed42a4 be a bit more flexible with the display frequencies we'll match 2022-12-19 14:11:21 +00:00
Ian Curtis 25604512f4 The model 3 (actually model 1,2 and 3) all used some crazy refresh rate of 57.524hz. If your screen refresh rate is 60hz, supermodel will work fine, but really run too fast. Anyway if you create a custom refresh rate, supermodel will automatically pick this, and set it when the emulator is in fullscreen mode. Apparently this works with most monitors, even cheapo low end ones. 
To active set your command line to:
-res=1920,1080 -vsync -fullscreen -true-hz

Replace the resolution with whatever your monitor's native resolution is.

Fernando Casas Schössow df7787f040 Keep Supermodel files (config, nvram, saves, etc.) in a predictable path when running on Linux 2022-12-12 16:49:07 -08:00
toxieainc db455ba5c1 add undefd codepath for correct use of the 18bit DAC path (which seems to be triggered for all games) 
the volume correction to bring the data back into a valid range is not really needed in practice though, only Daytona2 seems to need it, and also only extremely rarely, so lets just live with a tiny bit of clamping for that game then

while add it, make some formatting similar to MAME, and add one comment regarding a most likely wrong recent MAME change

Ian Curtis 40c8259130 Rewrite the whole project for GL4+. I figured if we removed the limitation of a legacy rendering API we could improve things a bit. With GL4+ we can do unsigned integer math in the shaders. This allows us to upload a direct copy of the real3d texture sheet, and texture directly from this memory given the x/y pos and type. This massively simplifies the binding and invalidation code. Also the crazy corner cases will work because it essentially works the same way as the original hardware. 
The standard triangle render requires gl 4.1 core, so should work on mac. The quad renderer runs on 4.5 core. The legacy renderer should still work, and when enabled a regular opengl context will be created, which allows functions marked depreciated in the core profiles to still work. This will only work in windows/linux I think. Apple doesn't support this.

A GL 4.1 GPU is now the min required spec. Sorry if you have an OLDER gpu. GL 4.1 is over 12 years old now.

This is a big update so I apologise in advance if I accidently broke something :]

toxieainc 6c24bf7c8f Optimize quad rendering by replacing the double computations for the area computation with the equivalent shoelace algorithm along with kahans algorithm to compute the cross products. In addition pull out the /w to the end, which increases precision even more. 
Thus making the result similar to the fp64 version, tested e.g. with harleys first person mode (all artifacts still gone as before).

Improves perf on low end boards (e.g. Intel) dramatically (10fps with harley before, now 70 on my laptop), and even on higher end (e.g. NVIDIA laptop, quads are now faster than tri pipeline on my laptop).

Ian Curtis 78eab65749 minor fix 2022-06-14 18:14:06 +00:00
Bart Trzynadlowski 7be381c9ba Added configurable refresh rate. Default is 60 but -true-hz on the command line enables 57.524 Hz mode, which some players report making Spikeout and the timing of combos in VF3 more authentic. The config key is RefreshRate and is specified as a floating point value. Should the desire arise, arbitrary refresh rates can be set in Supermodel.ini using this key but almost no validation of the value is performed. Thanks to forum user trap15 for the original code and PonMi for advocating for this patch to be included. 2022-06-12 17:51:57 +00:00

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.

 2021-11-30 23:01:37 +00:00
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.

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.

In xinput mode, lets the choice to have left and right gamepad motors vibrate together.
XInputStereoVibration = 1 (both motors) [default]
XInputStereoVibration = 0 (separate motors)

In sdl input mode, new control option to set minimum strength above which a Model 3 constant force command will be simulated on an sdl gamepad device.
SDLConstForceThreshold = 30 [default]
note : the vibration strength can be mod with SDLConstForceMax = [val]

SpinDizzy 309537d64e Balance initial value set to "0" rather than "false". "False" is interpreted as 0 when decoded as a float, so there will be no effect here, but this expresses the intended logic better. 2020-09-14 07:01:54 +00:00
SpinDizzy 72b2c0eb28 Fixed a longstanding bug that caused stereo channels to be flipped incorrectly. 
This was due to the initial audio buffer write position being aligned to the middle of a 4 byte (2 byte left, 2 byte right) audio sample.
In multi-threaded mode, some sort of race condition caused this alignment to be fixed until audio playback was temporarily paused (via pausing, loading a state, etc.)
Audio playback should now be fixed and work consistently in all cases.

SpinDizzy 60c923f45f - Reworked logging system to support output to multiple outputs: files, stdout, stderr, and syslog (OutputDebugString on Windows, syslog on other systems). 
- Added ordinal logging level: all, debug, info, error. Compiling with DEBUG defined is no longer necessary for debug logging. Be careful when logging debug level because it produces copious output.
- Fixed -enter-debugger options when compiled with SUPERMODEL_DEBUGGER.
- Command line parse errors no longer ignored; Supermodel will now exit.

Ian Curtis 816d541b98 Various SCSP improvements and code cleanup: 
- Ported MAME's implementation
- Corrected FM sound for songs in VF3 that use it 
- Music tempo now closer to real hardware thanks to emulating two SCSP chips.
- Add LegacySoundDSP config option for games with SCSP DSP glitches (ex. engine noises in Sega Rally 2, and loud garbage on Bahn's stage in Fighting Vipers 2)
- Renamed SysFPS to "SoundClock" (since raising this appears to adjust the sound frequency).

Ian Curtis 6f6c98c671 The translator map seems to work with paletted colour values too, and the result is not clamped. Colours are passed to the GPU as unsigned bytes to multiplying by 16 will overflow, so we do the logic in the shader. If we passed floats we could skip the shader logic. 2020-05-11 09:05:46 +00:00
Ian Curtis e2ad593e88 When the translator map is enabled the colour values seem to use 4 bits, 0-16. Why not 0-31 I don't know. Anyway virtua on is overflowing these values for some of the smoke effects. For us the numbers were wrapping around. Clamping is enough to fix this. (Thanks model123) 2020-05-07 19:34:22 +00:00

Ian Curtis 6b8a29105a Sutherland-Hodgeman clipping only works for planar primitives. Scud is rendering non planar quads and this breaks our algorithm a little when using the quad renderer. Stretching the near plane a few % is enough to fix it. 2020-01-04 13:48:14 +00:00

Ian Curtis 605dad2c02 Fix the sky in harley in first person mode where pixels in the sky are culled when they shouldn't be with the quad renderer. Basically we were running out of precision in a rare corner case. Doing the maths with double precision and casting back to float was enough to fix the issue. 2019-12-27 21:36:46 +00:00
Ian Curtis a5858e635d To calculate the mipmap value the opengl needs to calculate the difference in the texture coordinates between adjacent pixels. If there are no adjacent pixels the hw may need to spawn invisible fragments outside of the visible polygon. Our algorithm was culling these out so the mipamp calculation failed for edge pixels. Anyway this fixes quad rendering looking broken with the latest nvidia drivers. 2019-12-10 11:40:39 +00:00

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 06b43c45b3 Ocean hunter in the middle of the game is passing a few matrices with FLT_MAX inside them, which blows apart our near/far calculation. The hardware must have some method to sanitize the near/far for instance if you render something extremely close to the origin you will also blow apart any near/far calc. 2019-11-02 20:11:48 +00:00
