This is the first BETA for XMB RCO Patcher BETA 1.

Finally CHICKEN users can customize their PSP's ! ! !

This program will let you change your background waves, icons, battery bar / busy signals, volume bar, clicksounds, and bootlogos safely without risk of brick because all files are read from the memory stick.

This program can be used VIA HEN or normal CFW. These files were tested with
5.00 M33 but should work with all newer firmwares.
