PS3Hax member NZHawk has released another app known as the, Awesome Peek Poker. . To quote:

What is it? Awesome Peek Poker is a hombrew application that allows you to view/edit the lvl2 memory on the PS3 during runtime!

What for? Well, we can then apply patches to the memory. Things such as Hermes controller fix, PSN (Need the offsets) etc.
I presume as we find out more about the PS3 and lvl2 there will be more patches shared with the community.
And to begin with, why wouldn’t you wanna play with the ram!?

Note: Pressing square to dump lvl2 will save the dump to “/dev_hdd0/dump.bin” please use the ftp server app by blackbox or use Comgenie’s Awesome File Manager to copy this off to your pc. Please delete an existing dump before dumping again! It will increment to the file >.<!

Yes, there are a lot of bugs at the moment. But the core functionality is there! I released this ‘early’ due to school work taking priority for a few days.

You can grab future updates, and initial download release at his blog HERE.
