+ YM2151 - Yamaha YM2151 FM Operator Type-M (OPM) sound chip. Clock 3.58MHz [32.22/9]
+ M6295 - Oki M6295 4-channel mixing ADPCM LSI. Clock 1.000MHz [28/28]. Pin 7 HIGH
+ LH6168 - Sharp LH6168 8kx8 SRAM (DIP28)
+ CXK5814 - Sony CXK5816 2kx8 SRAM (DIP24)
+ CXK5864 - Sony CXK5864 8kx8 SRAM (DIP28)
+ VG-* - MMI PAL16L8 (DIP20)
+ SW1/SW2 - 8-position DIP switch
+ HSync - 15.6250kHz
+ VSync - 58.4443Hz

+ 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 the Deco '77' a '71' or similar?
