Carrying on from the following thread, so it's not too cluttered up with emulation chatter as requested
I converted it using PopstationGUI-300 because I can never seem to get the PSX2PSP program to produce anything that will work on my PSP.
As for how I run it on my PSP? I'm not entirely sure what that question means in terms of an answer I could give sorry, could you clarify for me? The best I can answer it for now is to say that I know that an EBOOT has to be in its own folder, which in turn has to be inside PSP/GAME. Oh and yeah I am running custom firmware 6.60, I have other games working on this setup so I know it's one that otherwise works.
In summary, I have the game working overall but not the music that is supposed to play while Pepsi-Man is actually running during the levels.
