Here is PRXdecrypter 2.4b - a minor update, with all the keys up to 6.20 courtesy of bbtgp, who spent many hours reversing to get them, whereas I just spent 10 minutes updating my source code. Thanks to the usual suspects + ErikPshat for some of the latest keys. UPDATE: 2.4b released (29th March) 2.4a --> 2.4b - Decryption error for an old key, tag 0x4C940AF0, fixed. - Decryption key added for pops_04g.prx from 6.XX firmwares - tag 0x457B1EF0 - Slightly more information when encryption is likely to fail (SHA-1 check warning) - NOTE: key for tag 0x2E5E10F0 does not appear to be working due to a new encryption method. I'll look into it. - New EBOOT.BIN key added for tag 0x2E5E12F0. As above, might not work. 2.4 --> 2.4a - New EBOOT.BIN key added - fixes "tag error 0x2E5E10F0" - Can extract the nand_updater/lfatfs_updater from old updaters again 2.3a --> 2.4 - All firmware keys up to 6.20 It's been 4 years since I first entered the PSP scene, and those 4 years were a privilege to be part of. A lot has changed since the days of kxploit. We've had a lot of fun battling Sony back and forth with their constant diversion and obfuscation tactics, watched a lot of drama unfold over some quite petty incidents, and seen some real triumphs of talent and ability from great minds such as Dark_AleX, but the past few months have seen a steady and obvious decline in the number of people following the scene and the number of developers still active. With this in mind, I thought it'd be worth letting those of you who are still around that I have sold my last remaining PSP, my silver first gen PSP 2000 - it served me well. I am still interested in the scene and will continue to update PRXdecrypter and PSPident as long as there is still a demand for them (please reply to this thread if you still want to see these apps updated). However, if/when the time comes where they require a major rewrite, which would obviously be impossible for me to do without a PSP, I will clean up and release the source code. For anyone wondering why I did this: partly because I don't see an imminent recovery in the PSP scene soon, partly because the hardware is outdated (and has been for a while), partly because it has been sitting in my drawer for months doing nothing, and a tiny bit because I wanted to free up some cash to buy a Nexus One (a quite amazing phone, if anyone is looking at buying one). Many thanks.
