Play 20-in-1 (Mapper 61) Online

Game Overview

20-in-1 (Mapper 61) is one of those old NES multicarts—twenty games crammed into one ROM, mostly simple arcade-style stuff. You get a mix of knockoffs and basic sports titles, the kind of thing you'd play for five minutes before moving on.

Some of the games feel like they were thrown in just to pad the count—like a barebones tennis sim where the ball moves in slow motion, or a space shooter with barely any enemies. But there are a couple of decent ones buried in there, like a stripped-down racing game that controls okay once you get used to it.

If you're into retro curiosities, 20-in-1 (Mapper 61) is an interesting time capsule, but don't expect hidden gems.
