I am unsure on da controls for psp dosbox - i tried all kinds of guides for all kinds of versions of psp dosbox but none of them seem to work, all i need is arrow keys to work but I can't figure it out?!
Oh, and I slightly modified DOSBox. I started with the one found at pspdosbox.co.uk but made it be able to use more memory, gave it a icon and did some other tweaks in the config. Works on my PSP (slim) but please try it on yours to see if you like it, if it's faster and if it works .

If any1 can figure out the controls to get arrow keys that would be great !
