Other DATA EAST Chips
--------------------------------------
DATA EAST 52 9235EV 205941 VC5259-0001 JAPAN (Sprite Generator IC, 128 pin PQFP)
DATA EAST 102 (M) DATA EAST 250 JAPAN (Encrypted 68000 CPU, 128 Pin PQFP)
DATA EAST 141 24220F008 (Tile Generator IC, 160 pin PQFP)
DATA EAST 104 L7A0717 9143 (M) DATA EAST (IO/Protection, 100 pin PQFP)
Small surface-mounted chip with number scratched off (28 pin SOP), but has number 9303K9200
A similar chip exists on Capt. America PCB and has the number 77 on it. Possibly the same chip?
- sound CPU seems to miss commands sometimes
- flipscreen is wrong
- should sprites be buffered (is there a Deco71?)
- should sprites be buffered, is the Deco '77' a '71' or similar?
