* Super Hi Impact Proto V4.0: You need to at least reset the high score
table from the UTILITIES menu. It's best to do a FULL FACTORY RESTORE

+Super High Impact
+Midway, 1991
+
+This game runs on (typical) Midway Y-Unit hardware. The PCB is a base
+board 'system' that can run other Y-Unit games by swapping ROMs and
+the protection chip.
