Unsure if this is off-topic, but I finally got around to buying a 573 and created a harness so I could play it on my MVS cabinet (space limitation, wife won't let me have more than one cab

)
The System 573 came with a DVD-R with no label, and as far as I can tell, it is using DDR Extreme Pro - is this the same thing as the 12-in-1 super disc people talk about, like the Dance Maniax video in the OP?
How do I switch between mixes on this disc? Otherwise, any advice on getting MAME CHDs to run on official hardware? I assume the MAME dumps contain the no-cart patches, but attempting to convert those to a bin+cue and burn them just makes my System 573 boot loop (tried DDR5M)
