Allright...this is going to sound lame but I need help getting emulators to work on my psp (fw 1.5). DCEMU doesn't seem to have any articles giving step by step directions (go figure) unless I totally missed something in which case I invite you to poke me in the eye with a stick...

you also need GTA:LCS, or i schould use that :s
