The InfoNES port for PSP has been updated. As usual PSP stuff needs a v1 bios to work, there is absolutly NO POSSIBILITY do run homebrewn on any other version than v1. Please be patient and do not bug homebrewn-autors and newsposters about making things to work with the american v1.5 bios. If anything should change, you can be sure to read it in the news.
