|Main CPU : 3 x MC68000 @ 12.5 MHz
Sound CPU : Z80 @ 4 MHz
Sound chip : YM2151 @ 4 MHz & SegaPCM @ 15.625 MHz
Max Colours : 16384 (4bpp - 16 per sprite, which go through a 16->512 indirection table), then selects which 512 color bank to take from 4096. This is used to do colour rotations (the red-yellow rotation of the lava sprites from Galaxy force for instance) without changing the color palette, also allows it to have sprites that rotate colors and sprites that don't on the same screen, and to get different levels of luminosity as well
Sprite Structure : Uses a linked list of sprites (each sprite includes the number of the next one)
Video resoution : 320 x 224
Board composition : CPU board + Video board
Board Features : 3 68K, nicknamed M, X and Y.
You have a sky gradiant, a first sprite layer which plugs into a full-screen rotation (seen in the the power drift/galaxy force screen tilt), then a second sprite layer (outrun type) on top of them which has priority, and they have full sprite zooming and scaling on both sprite planes.
This hardware uses no tiles at all.
Emulators : MAME - FinalBurn
