When trying to add Phantasmagoria game into ScummVM, after selecting folder ScummVM just freezes and the PSP shuts down with a flick sound (PSP users might be familiar with it as this behavior often happens with crashes).

I'm assuming it's because the game weights a lot (2GB+) and the PSP thinks the .pbp crashed so it shuts down itself, while in reality it's trying to load such a huge game. I've tried adding games like Lands of Lore (290MB) and it takes a while before you're prompted to the window screen afterwards (making you select the game ID, language, platform, etc.) which means it does take a while to read all the files.

Is there something that can be done regarding this?
