Need a little help
I have just got my minimus and was wondering which hex file to use so i can get the new backup manager2
to work?

You need the PSGroove with Hermes payload. But a bit of warning. It does not work on most games. If you want to have the best selection of backups running you will want to stick with psgroove 1.1 "patched" and the original backup manager for now.

From what I understand, you can still maintain the same compatibility with the new payload and backup manager if you just use the old way of loading backups with an original in the drive.

thanks for the help
is there a reason why modern warefare doesn't work with this?
