Sorry I didn't test for long but from my testing I noticed a couple of games run better with this build but not the one before it like Sonic Mega Collection proto now running with less audio issues, they're still there though so I don't know, the most noticeable is F-Zero AX not working at start up most of the tries, but it could well be related to something different so I don't know, sorry!Specify first if what games exactly, and if the games work normally with the Widescreen/4:3 correction turned off as it was before.
