If you’re a PS2 hardware sicko, you may be aware of the floating point problem If you were sad that it’s not possible to play stuntman in pcsx2, or your grand turismo recordings were not working quite right Well, you can, today, with my soft-float recompiler build in the reply

People may wonder, why do I care about maintaining a pcsx2 fork with accurate mechacon emulation? The reason is to enable others to do important work! Work like making arbitrary code execution for the Xploder Parental Game Lock. youtube.com/watch?v=XROote6V…

Here's the first release of the Xbox 360 Peer Pressure softmod. Blog post will be out in a few weeks with all the technical details. Barring any critical bugs I'll be "hibernating" for the next 2 months to recoup my sanity from working on this project github.com/grimdoomer/Xbox36…

MechaPwn folks are at it again. "XPEN" (X-Protection Enable) pin of the error correction DSP chip was discovered to be the toggle selection to turn on/off the behavior of -1 DSPs used on DTL-H hardware. This pin is pulled up internally by a resistor. Left unbonded in retail ICs.

Libby’s MechaLIBerator is now open source! Has real hardware risks so please only do it if you‘re comfortable. That said, if you have any dumps not in the list, please share so I can update it! Links in response
DiscoStarslayer@DiscoStarslayerSep 13
After 4 years of effort, I'm happy to announce that one of the final secrets of the PS2 has been broken wide open! It's been a long process of decapping, optical dumping, and now at last a software solution. Thank you Libby for finding the exploit from our dirty optical dumps!
