Here we are at last, the release of 6.61 Infinity. It's been over 11 years since the PSP was released back in 2004 and it's somewhat impressive how long this device lasted. There is no definitive end to the representative scene, it just gets quieter and quieter. I'm not claiming this releases is the end of the PSP, but it…

A small video update here demonstrating 6.61 Infinity working on the PSPgo. Will be working on getting custom firmwares working next and just generally heading towards a release.

Some time ago I mentioned that a 6.61 (6.60 then) boot-time hack was possible. This doesn't seem that long ago to me, but it actually has been almost a year since I mentioned it. Recently I've been rolling out actual device tests after many simulations and support software through the year. Last year all I had was a proof of…

These two functions are not normally imported so they require some special techniques such as syscall estimation to reach them in order to utilise their functionality.

Now, how does this kernel exploit work?

I've never had a blog before, so bear with me whilst I get used to all this fancy software (currently using wordpress atm). Back to the point, I made this blog in order to share research and…
