But the user is asking about a PSP ISO English patch. So if they have a Japanese version of Warriors Orochi 3 on PSP, they might want a patch to English. However, patching a game for the PSP on an actual device is complicated because of the PS Vita's security. Alternatively, if they're using an emulator like PPSSPP, maybe there's a mod or patch to enable English text.

Actually, the original Warriors Orochi 3 (Samurai Warriors: Orochi 3) was released for the PSP exclusively in Japan in 2008. The Western region got a version of the game called Samurai Warriors: Orochi 3 on PS3 in 2009, which was released in English. Then there's Warriors Orochi 4 and 5, which were released on other platforms like PS3, PC, etc., and are in English.

First, I need to clarify that Warriors Orochi 3 was released for the PSP in Japan as "Samurai Warriors: Orochi 3," while the Western regions got a different title. However, there's a version on the PS3 called Warriors Orochi 3, which might include English language support. Wait, actually, the original PSP version of Warriors Orochi 3 in Japan was "Samurai Warriors: Orochi 3," whereas the PS3 version for the West was titled "Warriors Orochi 3" and released later with English. So maybe the user is mixing up the versions. The PSP version of the original game (Orochi 3) didn't have an English patch, but maybe there's a mod or patch for the PS3 version? But in the US/UK releases, the PS3 version might have been released in English.
