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 ab367774d3 Introduce new config keywords. 
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 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 ?).

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.

Ian Curtis 38c3ff61f9 Clip scroll fog to viewport, instead of filling entire screen. Fixes fog bug in Daytona credits. 2020-09-08 09:10:24 +00:00
Ian Curtis aaa26f678c Update scroll fog logic. Should fix the credits in virtua fighter and daytona that have fogging applied to the background layer and shouldn't. 2020-09-07 16:25:18 +00:00
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.

SpinDizzy 97d61a970c Small oversight in the new SCSP code 2020-08-24 10:09:01 +00:00
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 d711afade1 Only need to clip against 4 planes for poly culling 2020-01-04 13:45:55 +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 06688de5fc Really should cull against 5 frustum planes. 2019-11-15 20:00:25 +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

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
Ian Curtis f634d19fdc Fix shader. Why this worked on my nvidia card .. I'm not sure. 2019-01-24 19:11:26 +00:00
Ian Curtis 8094c2e2b7 Composite the alpha layers at the end of rendering. To do this we need to mask the alpha pixels with the opaque pixels from the next priority layer. Fixes some overlapping shadows in vf3tb that have different priority layers. I assume that was a game bug, but it works on the real h/w. 2019-01-21 14:30:42 +00:00
SpinDizzy c171356f7d -Added support for specifying multiple sections simultaneously in INI

 2019-01-20 08:02:01 +00:00
Ian Curtis 864bb36b5a Technically backface culling should cull polys when the dot product = 0, since when it equals 0 the polys is perpendicular to the camera and thus invisible. When you complete sega rally2 (if you can get that far lol) the champagne is invisible. The reason is because all the face normals are 0. So when multiplied by the model matrix they are still 0 and get culled. Tweaking the condition to only cull polys when greater than 0 fixes this, and allows these 'bad' polys to render as they do on the model3. 2019-01-16 01:07:56 +00:00
SpinDizzy 98106df68b Inputs can now be configured on a per-game basis 2019-01-13 16:20:19 +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 3dbfa73734 Both lemans24 and dirt devils are rendering some totally transparent objects as the first model in each viewport. The HW seems to skip these entirely, and including them breaks our near/far plane calculations leading to Z fighting. 2018-09-19 20:43:41 +00:00
Ian Curtis e3255e45f3 Tweak the ratio for the near plane. Fixes missing text on the map indicator at the start of spikeout. The vertices are 0.003 units apart so a tonne of precision is required at the near plane to not depth test out. 2018-09-18 21:46:38 +00:00

Ian Curtis e4f5f0bcaf Sega bass fishing is starting some off the meshes with a shared vertex. Without having a previous vertex to share with, the values were just uninitialised and junk. The hardware itself seems to hold the value from the previous mesh, and sega bass fishing relies on this undefined behaviour to function correctly. Storing the cached vertices as member variables instead of locally to the function means it holds the values from the last mesh, and uses those values instead of random garbage. 2018-09-02 21:36:24 +00:00

Ian Curtis c7ffd0a808 Draw transparent polys to separate layers and composite at the end. This solves a tonne of transparency errors we had been battling with for a long time. The model3 is strange in the fact it only supports a max of two translucent overlapped polys. They are not blended into the frame normally. Doing this means the topmost translucent polys only are visible in the scene, the equivalent of doing a depth pass first, but without the added cost. 2018-06-16 21:31:29 +00:00

Bart Trzynadlowski 3f9b1b76e5 Added a stretch mode (-stretch) and modified new renderer's viewport code (hopefully correctly) to handle aspect ratio correction and widening the way the legacy one does. 2018-05-03 03:46:44 +00:00
Ian Curtis c6b86c0812 Render the opaque part of texture transparency in the first pass. Fixes numerous transparency related issues in lemans24 and some in ocean hunter. I don't really know if this is the 'correct' way of solving this because the real3d pro-1000 is a complete black box. There is still a lot we don't understand about how it handles transparency. 2018-05-02 20:10:02 +00:00

Ian Curtis 165926aa06 Modern hardware does backface culling in window space by calculating the face normal for the polygon, then doing a dot product against the view vector. The real3d pro-1000 on the other hand passes a pre-calculated face normal for each polygon which is used for culling. We were using this face normal to rewind the polygons so that regular backface culling would work. This worked 99.9% of the time. However this was failing on some models in Virtua Striker. The reason was because the pre-calculated face normals being passed were actually completely different to the actual face normals for the poly (not just inverted like you would expect). This broke our code. The solution was to emulate face culling directly in the vertex shader using the pre-calculated face normals directly. Only minimally tested this but hopefully there are no obvious regressions. 2017-08-29 10:27:29 +00:00

Ian Curtis cd5978773a Harry made some important discoveries with regards to fixed shading on the model 3 (per vertex poly brightness values). Firstly values are allowed to be negative, and they are used as a drop in replacement in the standard lighting equation for the normal dot light vector. This quite radically changes the brightness in LA Machine guns, but now correctly matches the arcade. 2017-08-19 20:06:31 +00:00

Ian Curtis 0efd4dac39 Finish fixed shading for 2.0 hardware. I'm pretty sure it actually works identically to step 1.5 hardware. The oddball is LA machine guns where the viewport ambient doesn't seem to effect the brightness. But the ambient works differently in this game because it uses the unclamped light model. Still need to investigate if the diffuse factor effects fixed shading. 2017-08-15 23:21:57 +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

Ian Curtis b1bd877b82 Ski champ for some reason is passing denormalised numbers for the modelscale. This is causing a NaN in our shader killing the lighting for these models, so we simply skip these, since they are essentially zero anyway.

Ian Curtis 9aa3f13777 We were force normalising the result of matrix * normal, which looked correct in most cases. But this didn't preserve the scaling of the matrix, or the scaling of the model normals which resulted in many over bright areas. On it's own this generally worked, but games like Star Wars looked quite broken. Harry correctly figured out if you scale these normals by the scaling value that is sometimes present in the culling nodes the lighting looks correct. Still more work to do to correctly figure out the model3's lighting model. 2017-07-29 16:30:30 +00:00

Clamping in the shader as we might need the full range of values for fixed shading. 2017-06-29 19:05:30 +00:00

Ian Curtis 21836c088c The real3d has a flag that allows the hw to skip polygons so that they aren't rendered. Sega rally2 uses this for the dust effects. Triangles or quads that have this flag are junk, and look like random corruption if you try to draw them. We assumed polys that shared vertices with these bad polygons were also bad. It turns out the last few shared vertices in these polys were in fact valid, and thus the entire quad/triangle strip should be drawn and not discarded. 2017-04-14 23:41:11 +00:00

Bart Trzynadlowski 2aa9dc7967 Rewrote large parts of ROM loading code to more gracefully handle merged sets where overwritten parent ROMs are not present. Better handling of multiple zip files. Optimized ROM loading when stride and chunk size are equal and got rid of safety checks that I don't believe are necessary any longer. 2017-04-03 01:03:38 +00:00
