Somehow this one slipped through the cracks. Deank released a nice multiMAN update bringing it to version 04.19.05. This update lets PS3 games using PS2 disc addons like Singstar to be used in multiMAN. Check out a note from deank and the changelog below.
" [PS2" prefix in folder name required
- Example: /dev_hdd0/GAMES/SingStar-Dance/[PS2 Pop] where [PS2 Pop] contains a backup of your PS2 disc
You can have up to 10 [PS2] add-on discs per PS3 game. In the screenshot above the following folder structure was used:
/dev_usb000/GAMES/SingStar-Dance <- this="" is="" the="" game="" listed="" in="" column="" br=""> mM detects the add-on PS2 discs and will list them in the pop-up menu when you load the game:
/dev_usb000/GAMES/SingStar-Dance/[PS2 Pop]
/dev_usb000/GAMES/SingStar-Dance/[PS2 Disney]
/dev_usb000/GAMES/SingStar-Dance/[PS2 Party]
/dev_usb000/GAMES/SingStar-Dance/[PS2]
To have a PS2 disc to be listed in the pop-up menu the folder name must start with [PS2 like in the examples above."
