Rock Band Unplugged

[l0udPL]

Try this:

Remove folder: memstick/psp/cheats completely
When cheats=ON run the game, then turn PPSSPP off.
Now, memstick/psp/cheats directory should be created with single, empty ini file. Paste that two lines to newly created ini file, save and turn ppsspp on again.
Run the game, press esc and in Cheats check if "Music hack" is visible and checked. Music should work now.
