I can confirm this working better than Multiman at the moment, for internal games. (for Waninoko CFW)
Now they actually run! (Gran Turismo5, F1 2010, Red Dead redemption) and updatings works fine.
Just let the manager fix the EBOOT permissions.
Everyone who is a WANINOKO hater, well.... i have no complaints about this firmware.
(and tampering with firmware, is at your own risk)
