97 Rabbit VG5330-B I5000
97? Tokimeki Mahjong Paradise(1)VG5550-B I5000
---------------------------------------------------------------------------
Not dumped yet:
unknown
To Do:
- raster effects (rabbit only?, see left side of one of the levels in rabbit)
- clean up zoom code and make zoom effect more accurate
Notes:
(1) This is currently in its own driver "tmmjprd.cpp" because it uses the
chip in a completely different way to Rabbit. They should be merged
again later, once the chip is better understood.
