Play 100-in-1 Contra Function 16 Online

100-in-1 Contra Function 16 is one of those weird NES multicarts where you get a mix of Contra hacks, bootlegs, and random retro games jammed together. The Contra stuff is the main draw—some levels are remixed, others just feel off, like playing with the wrong gravity or enemy spawns.

You’ll start with the familiar run-and-gun chaos, but then suddenly the screen glitches or a level loops endlessly. Some of the non-Contra games are barely playable, just filler to hit that "100-in-1" claim. It’s more of a curiosity than a proper collection.

If you’re into janky ROM hacks or just want to see how far Contra can break, 100-in-1 Contra Function 16 has its moments. But don’t expect a polished experience.
