Cyber Sleuth. According to OpDecoded representative Romsstar, the group is picking up the game due to the lower quality of translation produced by a contemporary circle of fan-translators that had previously been active on GBATemp. Progress on Lost Evolution until now has been slowed by the lack of dedicated translators, with almost four years of efforts yielding no functional patch. The OpDecoded team's Lost Evolution translation is being produced from scratch, with zero reliance on prior attempts by other groups.
OpDecoded was originally created in November 2012 to unofficially translate the games Bandai refused to officially localize, and released their translation patch for Digimon World Re:Digitize on the PlayStation Portable in June 2015 after overcoming numerous programming issues and production delays. Given the much smaller game size and greater development of DS hacking tools, the Lost Evolution translation project is unlikely to take as long.
