Bart Trzynadlowski	897b1acb21	Legacy renderer changes: ... - Updated shading model. Unfortunately, it is far from perfect but it seems to be the best I can do for now. Not really much of a difference from before except that the Scud Race castle is fixed at the expense of the Yosemite level in LA Machineguns being too bright. - Added lots of notes in the shading code. - Passing both specular coefficient and shininess to shader. This will probably break specular lighting for now until the shader is updated to use the shininess correctly. - Color table address in polygon RAM is now obtained from culling nodes as they are traversed (found this in the Pro-1000 SDK).	2016-05-14 06:25:35 +00:00
Bart Trzynadlowski	147faf37c9	Added palette bit to list of bits to dump for analysis	2016-05-14 06:21:56 +00:00
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	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	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	9249eaa29f	Fixed logic for clearing bottom layer. Added new functions to 2D renderer interface. Avoid drawing top and bottom surfaces when no layers are present there. Added some comments to tile	2016-05-08 19:27:08 +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
