Wheels & Fire

0.101u4 [David Haywood]


- 11th January 2007: Tomasz Slanina - Working on Wheels&Fire emulation. It's weird custom hardware based on gxf blitter. Req a lot of interrupts: 256 for raster ints, 400 (max) for blitter and 1 for vblank. So ~650 ints/frame. Interesting... I'm trying also to underestand how the raster effects works. Another task is to figure out how sprite zoom is done.

- 0.111u3: Tomasz Slanina added sprite X flip and removed unneeded hack in Wheels & Fire driver. Changed visible area to 336x256.

- 0.102u1: David Haywood and Tomasz Slanina improved Wheels & Fire, partial understanding of the blitter. Changed visible area to 512x512. Added dipswitches '0', '1' and 'Test / Game?'.

- 20th November 2005: David Haywood - Figured out the palette writes in Wheels & Fire which means the GFX pages have slightly better colours (at least for the gfx which should be on screen) the blitter format still doesn't make much sense yet tho. Update: Inputs have been mapped and Dox has managed to make some progress on the blitter format, allowing for some parts of the test mode font to show correctly. Update 2: Made some more sense of the blitter...

- 19th November 2005: David Haywood - Dox pointed me in the right direction to continue work on Wheels & Fire and patched up the code a bit so it boots further allowing work to be done on the video emulation. Unlike the usual TCH hardware this appears to use some kind of blitter device to show the graphics which are stored in the graphic roms as large 512x512 'sheets' rather than tiles. Emulating this will be something new for me if I actually get it going.

- 0.101u4: David Haywood added Wheels & Fire (TCH 199?).
