Encrypted eMMC Images
no$gba can emulate up to 12 consoles simultaneously, and expects the eMMC
images having following filename(s), in no$gba folder:
DSi-#.mmc ;eMMC for machine 1..12 (# = 1..C hex)
the eMMC images are encrypted with per-console keys, so decryption wont work
without knowing the console ID values. no$gba expects that info to be stored in
a 40h-byte Footer at the end of the file:
0000000h .. Encrypted eMMC image (usually 240Mbyte for DSi)
*F000000h 16 Footer ID ("DSi eMMC CID/CPU")*
F000010h 16 eMMC CID (dd ss ss ss ss 03 4D 30 30 46 50 41 00 00 15 00)
F000020h 8 CPU/Console ID (nn n1 nn nn nn 0n A2 08)
F000028h 24 Reserved (zerofilled)
