With PSJailbreak just around the corners it seems that PSJailbreak game dumps are creeping on to the internet:
Also for those unaware, PSJailbreak has a limitation on what games can be played on an external drive. Game dumps with individual files over 4gb currently can NOT be ran via external HDD, due to FAT32 restrictions. These game dumps will only work via internal PS3 HDD. PSJailbreak team is supposedly working on NTFS support.
