should of really also stated that im using an unmodified psp 1000 - the original model if that makes any diffcheers

That's why-your using an un-modded psp.You need custom firmware to run it.That message only comes up on psp's still running official firmware running a home made psx game.

Good news is you have PSP 1000, so regardless of what firmware it has, you can install CFW on it.So to start, what Official Firmware version are you running? 6.20?

With talk of that new exploit, it might be good news if on 6.20, means my guide ain't no help though...Pndora battery+megic memory stick combo is always useful :)

You need custom firmware to play ps1 games. If your running the latest official firmware, than it will be hard to get custom firmware on it.

aaaaah right lol i see, thanks for the replys everyone, urm yeah im running the 6.20 firmware lol just had to check, lol figured it was sumthin to do with that but im new to this stuff so figured id best check, ill give it a go with the custom firmware n see what happens, is there any spercific software i need?thanks again everyone appreciate it lol
