Although I have no interest in Ys 6 on PSP (finished the PC ver though), what bothers me about current PSP games is the required BIOS update. Dunno if all the current games require a certain BIOS level though. Anyway I recently bought Gradius Portable (1,2,3,4, and Gaiden in widescreen format) and it requires v2.50 of the BIOS in order to run. This irks me because this would obviously prevent me from using homebrew stuff on it. So I have a game I'm likely not going to play since I have v1.0 on my PSP now (best for homebrew).
Sorry for somewhat derailing this thread with my mini rant, but I was wondering if Ys 6 also had a similar BIOS requirement.
