+Sea Hunter (?) by unknown manufacturer
+
+The not working PCB has the following main components:
+
+1 chip covered by the 'Sea Hunter' sticker (M68000?)
+1 scratched off chip (near 2203)
+1 YM2203C
+2 8-dip banks (near 2203)
+1 18 MHz OSC (near the chip covered by the sticker)
+1 16 MHz OSC (near 2203 and scratched off chip)
+4 ROMs (mix of 27C010A and 27C1001)
+2 PALs
+2 HM6264 SRAMs
+
+Strings in ROMs seem to point to a tile-matching game from a Korean manufacturer.
