The Custom Firmware 5.50GEN-C will soon be released and offer the ability to run games that require the 5.55 and 6.00 firmwares without any intervention from the user
Before 5.50GEN-C, to launch a recent game, it had to be dumped from the UMD, patched with our Game Decrypter and rebuilt it with UMDGEN. Thus, a large number of long and boring manipulations were required.
With the Custom Firmware 5.50GEN-C, you will not have to do anything like this. You will just have to put one UMD in the drive and it will start simply. The ISO also start without needing to modify it and demos such as Metal Gear Solid will start too.
