Opus 5.5 can translate pretty much any retro game in about 4 hours.

Opus 5.5 can translate retro games in approximately four hours, with users reporting successful translations of GBC games that are very playable and have improved scripts. This process, which works on original hardware with a flashcart, has been used multiple times with consistently solid results. One user is currently working on a BBK e-dictionary game, 伏魔记, a 2004 RPG, highlighting the ability to translate games that would otherwise remain untranslated.
