  • 89c987fae1 basic spotlight code Ian Curtis 2016-05-26 00:08:12 +0000
  • a0910f96fb Fixed fog in legacy 3D engine. Now computed same as new engine, with 4-bit light modifier and corrected fog mixing in shaders. Bart Trzynadlowski 2016-05-25 04:00:02 +0000
  • 6dc35f9563 Updated legacy engine vertex shader to use specular shininess and coefficient along with old equation. Still not correct (too strong compared to the old method). Bart Trzynadlowski 2016-05-25 03:10:36 +0000

  • 7e3c097a31 remove debug code Ian Curtis 2016-05-16 17:26:53 +0000
  • 828fd8ebb4 Fog start is apparently the fog value at the viewport (0,0,0) I guess like an ambient value. Default value is negative Ian Curtis 2016-05-16 17:10:04 +0000
  • 9e279a0c1f Non luminous polygons seem to be effected by the lightModifier also. API seems to have no restriction in this regard, neither does the SDK. The ocean hunter requires this for some of the 2d stuff. Light modifier values only seem to exist between 0-16, which is strange for 5 bits of precision. Possibly top bit disables the effect and lower 4 bits are the value. This clearly differs from the SDK, but without this the values come out clearly wrong. Ian Curtis 2016-05-16 10:49:00 +0000
  • 62eafacfc3 adjust (hopefully correct) fog equation Ian Curtis 2016-05-16 10:44:16 +0000
  • bc08276d60 preliminary specular Ian Curtis 2016-05-15 16:24:49 +0000
  • c9147bc93d - Removed a stale comment Bart Trzynadlowski 2016-05-14 06:31:44 +0000
  • 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).

  • 147faf37c9 Added palette bit to list of bits to dump for analysis Bart Trzynadlowski 2016-05-14 06:21:56 +0000
  • c4b5b185c6 Disable light modifier on fog, seems not to work .. values don't make sense. Maybe the model3 doesn't use these. Ian Curtis 2016-05-13 19:26:10 +0000
  • c8f8cd1655 remove dead code Ian Curtis 2016-05-13 08:40:53 +0000
  • e295ad6868 double up polys for two sided polys, fixes some diffuse lighting problems Ian Curtis 2016-05-13 08:39:48 +0000
  • ddf3d5213d FLT_MAX -> std::numeric_limits<float>::max() Bart Trzynadlowski 2016-05-10 03:08:36 +0000
  • 8c082abab9 Added some IRQ-related code (commented out for now) from MAME findings. May incorporate in the future when investigating IRQs and timing again. Bart Trzynadlowski 2016-05-10 03:08:03 +0000
  • 34c81eabee update header documentation Ian Curtis 2016-05-09 16:53:12 +0000
  • 43add90d2f Fix bad texture seems Ian Curtis 2016-05-09 16:26:34 +0000
  • 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. Bart Trzynadlowski 2016-05-08 21:17:02 +0000
  • a9095e6c8e Added a register read handler for tilegen (although nothing seems to benefit from it) Bart Trzynadlowski 2016-05-08 20:30:45 +0000
  • 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 Bart Trzynadlowski 2016-05-08 19:27:08 +0000
  • 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. Bart Trzynadlowski 2016-05-07 21:54:03 +0000

  • 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 Bart Trzynadlowski 2016-04-30 16:23:25 +0000
  • 23a5839d46 Daytona seems to use 3 bits for texture transparency, will figure it out later but for now this works Ian Curtis 2016-04-30 09:02:38 +0000
  • 30ca1792bb Fix fixed shading maths Ian Curtis 2016-04-30 08:58:13 +0000

  • 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). Bart Trzynadlowski 2016-04-29 03:56:06 +0000

  • 34e8f00382 Legacy engine: extracting fixed shading component (but still can't use it because unsure of how to activate) Bart Trzynadlowski 2016-04-28 13:18:15 +0000

  • 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) Bart Trzynadlowski 2016-04-24 01:50:03 +0000

  • ef87093824 Debugger compilation fixed: CBus -> IBus Bart Trzynadlowski 2016-04-11 03:39:19 +0000
  • 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). Bart Trzynadlowski 2016-04-11 00:19:10 +0000
  • 775256118d Fixed Magical Truck Adventure country check (accidentally removed a line in previous commit). Bart Trzynadlowski 2016-04-10 23:57:55 +0000
  • 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. Bart Trzynadlowski 2016-04-10 21:47:07 +0000
  • 198a469ff7 Created IEmulator interface, renamed CBus to IBus and CPCIDevice to IPCIDevice. Frames now rendered when emulator paused. Bart Trzynadlowski 2016-04-10 03:42:41 +0000

  • 6d9426759b Fixed texture enable bit (fixes Star Wars light sabers and Sega Rally 2 cones) and added a hack for (and more comments about) color modulation. Scud Race, Sega Rally 2, LA Machineguns, etc. look correct now, but Fighting Vipers 2 shadows are no longer dark enough. Other bugs may exist. Bart Trzynadlowski 2016-04-04 03:50:24 +0000
