Ian Curtis c4b5b185c6 Disable light modifier on fog, seems not to work .. values don't make sense. Maybe the model3 doesn't use these. 2016-05-13 19:26:10 +00:00
Ian Curtis c8f8cd1655 remove dead code 2016-05-13 08:40:53 +00:00

Bart Trzynadlowski ddf3d5213d FLT_MAX -> std::numeric_limits<float>::max() 2016-05-10 03:08:36 +00:00
Bart Trzynadlowski 8c082abab9 Added some IRQ-related code (commented out for now) from MAME findings. May incorporate in the future when investigating IRQs and timing again. 2016-05-10 03:08:03 +00:00
Ian Curtis 34c81eabee update header documentation 2016-05-09 16:53:12 +00:00
Ian Curtis 43add90d2f Fix bad texture seems 2016-05-09 16:26:34 +00:00
Bart Trzynadlowski 846c9d0edd Reverted stencil mask change. This reintroduces the Scud Race 'ROLLING START' bug. Previous 'fix' did not work for Magical Truck Adventure anyway and also broke some games (Daytona 2 transmission and course select screen, ECA title screen). The stencil mask is not shifted by 16 pixels and I suspect that either there is some unknown trick to horizontal scrolling or that the behavior is affected by hidden raster timing registers hidden in the JTAG interface. 2016-05-08 21:17:02 +00:00
Bart Trzynadlowski a9095e6c8e Added a register read handler for tilegen (although nothing seems to benefit from it) 2016-05-08 20:30:45 +00:00

Bart Trzynadlowski 5d048958b9 Rewrote 2D renderer and fixed 2D layer priorities, stencil mask clipping (Scud Race 'ROLLING START'), and cleaned up code. Unfortunately, the new code is about 50% slower, mostly due to the need to perform stencil clipping after scrolling. 2016-05-07 21:54:03 +00:00

Bart Trzynadlowski 48767b2267 Legacy engine: fixed per-vertex fixed shading to incorporate Ian's findings that the intensity value is signed and that fixed shading applies only when lighting is enabled 2016-04-30 16:23:25 +00:00
Ian Curtis 23a5839d46 Daytona seems to use 3 bits for texture transparency, will figure it out later but for now this works 2016-04-30 09:02:38 +00:00

Bart Trzynadlowski 57d5bc8367 Legacy engine: preliminary per-vertex fixed shading. Only limited testing with LA Machineguns (appears to work), Sega Rally 2 (appears okay), and Scud Race (fixes expert course bridge but not other mis-colored polygons). 2016-04-29 03:56:06 +00:00
Ian Curtis 2785ecd25f read front buffer 2016-04-28 22:15:36 +00:00

Bart Trzynadlowski 9baa0488e3 Changed save state file version (r340 changed Real3D save format, breaking compatibility with older states, and states were probably already incompatible with 0.2a) 2016-04-24 01:50:03 +00:00
Bart Trzynadlowski 3bd8e20639 Fixed white space and warnings. Fixed second argument to -dis option in cases where other numerical parameters are specified on command line. 2016-04-24 01:40:16 +00:00
Bart Trzynadlowski 908d979cd7 Flattened out nested if-statements in new engine's fragment shader to improve compatibility with older GPUs (e.g., NVS 300) 2016-04-22 23:46:49 +00:00

Bart Trzynadlowski 2524f2e837 Fixed Magical Truck Adventure by emulating VROM texture ports as a FIFO. Now, VF3 crashes on Akira's stage (and probably the other stages with texture glitches). Other games may be affected, too (not thoroughly tested yet). 2016-04-11 00:19:10 +00:00
Bart Trzynadlowski 775256118d Fixed Magical Truck Adventure country check (accidentally removed a line in previous commit). 2016-04-10 23:57:55 +00:00
Bart Trzynadlowski 7ade3a6abb Magical Truck Adventure expects 0x03 to be returned from MIDI control port (thanks, Ville). Game now boots but crashes because VROM texture uploads clobber memory for some reason. 2016-04-10 21:47:07 +00:00
