Yoshihiro, a popular homebrew maker and member of team GENyUS, has just released a homebrew utility wherein you can play PSP games on a custom firmware requiring the latest firmware updates.  

This release installs the official firmware 6.00, custom firmware 5.50 GEN-B2 on any PSP flashable, any official firmware and can convert Kit Despertar del Cementerio V8 kit XGEN Pandora to flash any PSP2000 and PSP1000 directly to 5.50GEN-B2. 

This second version has the following features:

* XGen Updater:

   - Changing the location of “Flash install CFW 5.50 GEN-B2, which is now in the forefront of the menu

   - Support Official Firmware 6.0 and added a test tool for the latest encryption keys Sony

   - The VSH Menu has been corrected for Custom Firmware 5.50 GEN-B2

* XGen Pandora : Changing the location of “Flash install CFW 5.50 GEN-B2, which is now in the forefront of the menu

   - The VSH Menu has been corrected for Custom Firmware 5.50 GEN-B2

   - One option for the test kit Despertar del Cementerio V8 that will get you started on the M33 firmware from your memory card 

The difference between these two utilities is that XGen Updater will directly install the Custom Firmware 5.50 GEN-B2 on the console while the Pandora XGen will update the kit Despertar del Cementerio v8 to install it on 5.50 GEN-B2 when used (instead of 5.00M 33).
