Ooooh, I check out that website you gave me. It looks like that emulator hasn't been updated in awhile. Da last one was in 05. Did it come with a list of compatible games? Cuz I couldn't find it on da website.
That's probably da reason why it won't run Crystal Version. It probably hasn't been program to run every GBC rom...maybe...
Yeah, both of them are Game Boy games. I imagine you could probably even get Gold and Silver to run...Thing is, Crystal version is a Game Boy Color...That's why I asked you have you tried out any other GBC games, beside Crystal Version in your PSP?
Oh, wait...You said you were using an emulator too? Is it Visual Boy Advance?
Seriously...Strange, but I'm pretty sure Crystal Version don't have AP protection in it. LOL
And I still don't own a PSP...sadly, so I don't what to tell you to get pass your problem. But if use Visual Boy, I'm sure you can run Crystal Version with ease...But I know you want to play it on da go, right?
