Button-mashing through the tower with my son has been a blast, and the sprites hold up surprisingly well on the small Game Gear screen. The cart booted right up on my NTSC system with no fuss.

Wasn't sure how a fighter this big would hold up on a tiny handheld screen, but the sprites and controls came through fine. Cartridge booted right away on my NTSC system, no cleaning needed.

Plugged it into my old Game Gear and it fired up right away, no blowing on the cartridge needed. The blood code still works too, which honestly surprised me for a used copy.
