Play 20-in-1 (Mapper 231) Online

Game Overview

20-in-1 (Mapper 231) is one of those old NES multicarts—you know, the kind that crams a bunch of random games onto one cartridge. The selection's a mixed bag, mostly simple arcade-style stuff, some clones of bigger titles, and a few oddball picks that feel like they were thrown in just to hit twenty.

You boot it up and get a basic menu, no frills. The first few games I tried were rough—janky controls, flickering sprites, the usual NES bootleg quirks. But there's something weirdly charming about it, like digging through a bargain bin of forgotten games.

20-in-1 (Mapper 231) isn't great, but if you're into obscure retro stuff, it's a curiosity worth poking at for a bit.
