The PSP is region free and there's also language settings on the PSP. I assume that it'll ultimately be used like the language settings on a DVD player. Certainly for UMD video anyway. Twoud be nice to be able to import Japanese games that then play in English when the PSP is set to "English".
System Settings: System Language: English.
Video Settings: Menu Language, Audio Language, and Subtitle Language: English
I'm probably going to import Puyo Puyo Fever because my family and I are addicted to it. I'm already becoming a Lumines addict.
I hope that homebrew/emu becomes possible rapidly because I want to see Tetris and some other simple classics available without having to pay $40 for each new ports and it's accompanying new 3D version.
