I have succeeded in producing raw files from chd thanks to numDHC.
 
	 
 
	I was able to generate this from a MAMEchd in DrumManiaV.
 
	 
 
	Please refer to this if you are having trouble.
 
	 
 
	Also, I am trying the same boot method as ThrillDrive3 with P2io, but I would like to know how to decompress or generate EFI when doing an EFI boot.
