Today a file titled appears to have hit the Internet, with the size being 436 KB (446,732 bytes) and containing the official (C) $ony PSP Dev Kit Libraries! This is exciting news indeed, as up until now nothing from the heavily watermarked PSP $DK has surfaced publically. As a result, Hammer[PS3News] has extracted the PSP v1.50 Error Codes for reference.

Needless to say, the actual files are illegal to possess if you are not a licensed developer so NEVER discuss them on our Web site... but those interested can drop by EFnet #PS2Ownz for related chat. Ironically, the legal PSPDEV ToolChain has recently been released as well. Cheers!
