Specs? Would be helpful.
In the meantime, I found this on the PCSX2 wiki on the compatibility (I recommend finding your chosen game first to see if there are any fixes or known problems)
"SkipMPEG hack, Runs above full speed., Intro IPU hangs and console floods with IPU errors."
"Game is playable at good speed by enabling skipmpeg hack., Intro IPU Still hangs with IPU1 Normal Error"
"NintenDON'T sue me please haha"
