Saturn emu for psp not working...

I have custom firmware 5.00m33v6, it's a psp slim, I got yabuse (first release) and it refuses to go past the song boot screen...After the splash, it says "this game cannot be started" and it's annoying...What do I need to get this going, I downloaded a pack with the bios, but where do I put them, do I need a special folder, and does it matter if it's in .bin or .rom format?And any other configurations I may need to do?And would daytona work you guys reckon?Thanks in advance...

Not that this would help matters any but I was looking at saturn emulators just yesterday and from what research I did its claimed that its not a very stable emulator on other "game" systems but its better off on a PC

... i just wanted to see if it would load, and hopefully, bring some hope for this thing (even just playing at 1-2fps would make my day)...Oh well, I've backed it up until the time it's ressurected.

I'm not saying its not worth trying out ;D

Saturn is an extremely complex platform and thus is difficult to emulate.
