I've been doing a textual translation for 2 PSP games connected to the "A Certain Magical Index" series. For one, the Index PSP game, I have a complete translation of the game's story mode and the character movesets. I haven't translated the character summary pages, menus, or the tutorials.
For the second, the Railgun PSP game, I have a partial story mode translation covering the first 3 of 5 chapters, plus the corresponding sections of Topics and Event Log for those chapters. I am taking a break but I do intend to finish the remaining chapters.
I have been posting these translations in textual format with screenshots on my blog (jerutz.wordpress.com), but if anyone's interested in making a patch for either game I'd be willing to share my work.
