Toaru Kagaku no Railgun English translation
とある科学の超電磁砲 · A Certain Scientific Railgun
A complete English patch for the Japan-only A Certain Scientific Railgun visual novel on PSP, including its bonus DLC chapter.
What it is
JERUTZ announced this finished translation on their blog in June 2022, after a long wait. The patch is the result of a joint effort: Kotcrab handled the technical side, ItsumoKnight and IgorAkou contributed to the work, and JERUTZ translated.
What's translated
The whole game can be played in English. The download also includes a second patch for the game's special DLC chapter, so that extra episode can be read in English as well.
Playing it
The patch is applied to your own copy of the Japanese game: you drop the disc image on the included batch file and it builds the English version. The DLC folder is patched the same way and then copied to the memory stick (or to PPSSPP's equivalent folder). On real hardware, the blog post notes that a high memory layout option in the custom firmware's recovery menu must be switched off. Everything is explained in the announcement linked below.
