Chou Genjin 2 English translation
超原人2 · Super Genjin 2 · Super Bonk 2
An early English patch by Gaijin Productions for the Bonk sequel that never left Japan; some compressed graphics are still in Japanese.
The game
Bonk is back, smashing through jungles and odd dream-like levels head first. Power-ups transform him in strange and funny ways, and the game keeps the series' light, silly tone.
What's translated
Gaijin Productions released this patch in April 1999 as version 1.00. The text is in English, but the team left some graphics untranslated because they are stored compressed, so a little Japanese remains on screen. There is not much reading in a platformer, so this hardly gets in the way.
Playing it
Apply the patch to your own copy of the Japanese cartridge's game following the readme. The patch's page on romhacking.net has the download and details.
