Asuka 120% Limit Over is a modded version of the 1997 Japanese Sega Saturn fighting game Asuka 120% Limited BURNING Fest. The rumor is that the original development team was responsible for the patch that was circulated on the internet in Japan. Around 2007, some fans at Lost Levels’ forum discovered this mod and it slowly started making the rounds on the English speaking parts of the internet.
Now another fan has released an English fan translation for this mod. Essentially, all of the characters names are now in English so you can more easily select them via the in-game menus. They also documented their translation process fairly well.
You’ll still need a patched version of the original game in BIN/CUE format to apply the translation, but at least this game is now more accessible for the rest of the world.
