Don't update those PSP's! If you've already gone as far as 6.10, don't go any further! (unless you can pandora yourself back) as FreePlay has discovered that Sony did indeed discover and block the Save Game Exploit found in Firmware 6.10. That very same one that was demonstrated on the PSP Go running “Hello World”. So lets hope maybe we will see a release since its blocked? And of course games that require Firmware 6.20 will not play on Custom Firmware enabled machines. Even 5.50 GEN-D2. Were coming to have to wait for either a new Game Decrypter that decrypt Firmware 6.20 or a new CFW.
