if you want to be able to play 'backed up' games then yes but if you only into the homebrew scene (which i doubt ) then it will be fine you can do a google for the bios's but i dont know if you have a pro or sx chip so read up somewere on which one you need or ask someone hope i was of help x
Much help . However now that I updated to 1.4, I get a disk read error when I try to play JP games. I also tried my freeloader and got the same read error. I'm gonna try a few more games but so far I've only gotten games to work under the default bios boot. Is there an official manual as to how the flashing and bios and stuff work and troubleshooting? That would be incredibly helpful. Edit: I have qoob pro
