Is my graphics accelerator thingy working?

[FluffyGang]

Question from a not-very-technically-minded player:

I have installed ALL the files onto a Memory Stick on my Clie NX70V, and the game seems to play OK (apart from occasional stuttering sound and 'crashes' when lots is happening all at once, as mentioned in other postings)... but how can I tell whether or not the graphics accelerator is working? One of the other posts suggests that it won't work from external memory... is this definitely true?

I'd be grateful if someone could clarify once and for all exactly which files can be stored on the Memory Stick.

Cheers,
