R-Type Final videos play decent but have a jitter to them for me and a few tutorial videos will freeze for a few seconds in some places and then continue on. Plays well in game and this is without speed hacks. Couldnt get it to run with previous versions of pcsx2 though. I am using the svn 351 build.
