Play FC Genjin - Freakthoropus Computerus (Japan) Online

Game Overview

Ever stumble across FC Genjin - Freakthoropus Computerus while digging through old NES imports? It’s Bonk—yes, that caveman with the comically oversized head—but squeezed onto a Nintendo cartridge instead of TurboGrafx. The whole thing feels like someone remade Bonk’s Adventure with a box of crayons and a fever dream. You’re still headbutting enemies into oblivion, but now everything’s chunkier, the colors are cranked up to neon, and somehow there’s even more floating meat to chomp mid-air.

First level throws you right into it: bouncing off mushrooms, smashing weird little gremlin things, and discovering that dinosaur drumsticks restore health (because of course they do). The controls are weirdly smooth for an NES game—Bonk’s jumps have this satisfying weight to them, and the head-slams feel stupidly powerful. It’s got that same chaotic energy as the original, just filtered through Nintendo’s hardware quirks. Found myself grinning at the absurdity of it all by the time I reached the first boss, a grinning… thing that shoots bubbles?

Honestly, half the fun is seeing how they adapted Bonk’s madness for the NES. The music’s tinny but catchy, the levels are packed with little secrets, and it’s just different enough from the TurboGrafx version to feel fresh. If you’ve got a soft spot for weird retro platformers, this one’s a trip.
