Item description:

Here it is folks! From homebrew devs Coldbird, Virtuous Flame (aka Liquidzigong) and the rest of Team Pro comes the long awaited update of their Pro custom firmware for the PlayStation Portable. Changelog (translated):

BUG repair and reconstruction of the accumulation of a large number of code
Mounted support PSPGO UMD Video
Fix Inferno/np9660 standby mode occurs when the drive noise
Updated decryption component, 6.20/6.3x version 6.60 will add support future encryption type PRX
Add to 6.20/6.3x added 6.60 function 6.60 save game compatible with the future
Add 6.60 PRO-B9, support for 6.60 firmware (in theory, support all PSP hardware, including version 11g)
Add CPU frequency 166/83
Added compatibility with the ISO played KHBBS_patch support

Developer's Note: I recommend the old version of PRO users began to appear in the game after the 6.60 upgrade PRO-B9, so as not to archive the user is not compatible with 6.60. 6.60 PRO-B9 use kernel vulnerabilities from some1/Davee/Proxima/Zecoxao the 6.60 downgrader. To express thanks again.
