Prior to this, without a new PSP Custom Firmware update available those unwilling to upgrade their official PSP Firmware have been locked out of playing a lot of the new PSP games.
Yoshihiro was reportedly able to successfully play MotorStorm: Arctic Edge on 5.03GEN (PSP-3000 and PSP-2000 v3) and 5.50GEN (PSP-2000 and PSP-1000).

To quote, roughly translated: Today, Yoshihiro presents a tool that will please all the players in the community: Game Decrypter, which will allow owners of games requiring firmware 5.55 can play on Custom Firmwares 5.50GEN-B and 5.03GEN.
To do this, you will get the file EBOOT.BIN an ISO that you created with the utility UMDGen.
Most games asking the 5.55 can be treated with this tool. Some games (list available soon) will be impervious to manipulation, they require a patch to the image of him created to run Soulcalibur: Broken Destiny. But generally, you can finally play your own backups, without having to install official firmware.
