                                   Issues
                              [WEC Le Mans 24]
---------------------------------------------------------------------------

- The parallactic scrolling is sometimes wrong


---------------------------------------------------------------------------
                                   Issues
                                [Hot Chase]
---------------------------------------------------------------------------

- Samples pitch is too low
- No zoom and rotation of the layers


---------------------------------------------------------------------------
                               Common Issues
---------------------------------------------------------------------------

- One ROM unused (32K in hotchase, 16K in wecleman)
- Incomplete DSWs
- Sprite ram is not cleared by the game and no sprite list end-marker
  is written. We cope with that with an hack in the Blitter but there
  must be a register to do the trick


Revisions:

05-05-2002 David Haywood(Haze)
- improved Wec Le Mans steering

05-01-2002 Hiromitsu Shioya(Shica)
- fixed Hot Chase volume and sound interrupt

xx-xx-2003 Acho A. Tang
[Wec Le Mans 24]
- generalized blitter to support Wec Le Mans
- emulated custom alpha blending chip used for protection
- fixed game color and sound volume
- added shadows and sprite-to-sprite priority
- added curbs effect
- modified zoom equation to close tile gaps
- fixed a few tile glitches
- converted driver to use RGB direct
- cloud transition(needs verification from board owners)
- fixed sound banking
- source clean-up

TODO:
- check dust color on title screen(I don't think it should be black)
- check brake light(LED) support
- check occational off-pitch music and samples(sound interrupt related?)

* Sprite, road and sky drawings do not support 32-bit color depth.
  Certain sprites with incorrect z-value still pop in front of closer
  billboards and some appear a few pixels off the ground. They could be
  the game's intrinsic flaws. (reference: www.system16.com)

[Hot Chase]
- shared changes with Wec Le Mans
- removed junk tiles during introduction(needs verification)

* Special thanks to Luca Elia for bringing us so many enjoyable games.

    10.b            Triggers the blit
    11.b            Number of words per transfer

    The list contains 4 bytes per blit:


    Offset:

    00.w            ?
    02.w            offset from Base address


    Note:

    Hot Chase explicitly copies color information from sprite parameters back to list[4n+1](byte ptr)
    and that tips me off where the colors are actually encoded. List[4n+0] is believed to hold the
    sprites' depth value. Wec Le Mans will z-sort the sprites before writing them to video RAM but
    the order is not always right. It is possible the video hardware performs additional sorting.

    The color code in the original sprite encoding has special meanings on the other hand. I'll take
    a shortcut by manually copying list[0] and list[1] to sprite RAM for further process.
