Messing around with the alternative emulators vs built-in.
builtin... running Golden Sun is horrible... unplayable, i'm talking like possibly 15-20fps, with aweful frameskip
gpSP... running Golden Sun, beginning scene has lots scene motion, it runs about 40-47fps... not bad... overclocked the cpu to 600mhz, bingo, steady 53-56fps, which is extremley playable and very enjoyable.
I prefer playing RPGs on this unit WAY more than my AGS101 as the screen size and form factor is just way better.
Seems it tops out about 624Mhz... got a screen garbling if i went higher for any length of time. I'll do some more testing. Mario Kart runs 60fps frameskip off.
