The callback is passed:
- layer number (0 = FIX, 1 = A, 2 = B)
- bank (range 0-3, output of the pins CAB1 and CAB2)
- code (range 00-FF, output of the pins VC3-VC10)
NOTE: code is in the range 0000-FFFF for X-Men, which uses extra RAM
- color (range 00-FF, output of the pins COL0-COL7)
The callback must put:
- in code the resulting tile number
- in color the resulting color index
- if necessary, put flags and/or priority for the TileMap code in the tile_info
structure (e.g. TILE_FLIPX). Note that TILE_FLIPY is handled internally by the
chip so it must not be set by the callback.
