+/* Poke Champ */
+
+/* This is a Korean hack of Data East's Pocket Gal
+
+ It uses RAM for Palette instead of PROMs
+ Samples are played by OKIM6295
+ Different Banking
+ More Tiles, 8bpp
+ Sprites 4bpp? instead of 2bpp
+ Many code changes
+
+ Todo:
+
+ Fix colours
+ Fix sound banking
+ Verify frequencies etc.

+-The ROMs are labeled as "Unico".
+-The CPUs and some other chips are labeled as "SEA HUNTER".
+-The chips with the "SEA HUNTER" label all have their
+ surfaces scratched out, so I don't know what they are
+ (all 40 -pin chips).
+
+ROMs 1 to 4 = GFX?
+ROMs 5 to 8 = Program?
+ROM 9 = Sound CPU code?
+ROM 10 = Sound samples?
+ROM 11 = Main CPU code?
+
+-There's a "copyright 1987 data east corp.all rights reserved"
+ string inside ROM 11
+
+-Sound = Yamaha YM2203C + Y3014B
+
+-Also, there are some GALs on the board (not dumped) a
+ 8-dips bank and two oscilators (4 MHz and 24 MHz, both near
+ the sound parts).
