Just asking cause I have yet to acquire a Arcade card, so I tried it in Magic Engine using System Card 3.0 and it kept bombing out right after first stage character selection.  Just curious if this is a known issue with Magic Engine, or if anyone else was having actual problems with the discs....lol
I was pretty sure it was the emu.... glad to hear there is much sapphire goodness going around!!  

Thanks again!!
PS: Once I get an ACD, I'll let ya know that the discs work.  =)
