I just ran through this thread. I can't believe you have enough time to keep up with all this Andreas, If game mode and RSX access are available why the F##k not go for it? MorphOS can run in 256MB easily (just ask any Efikla owner stuck with 128MB). A 3.2 Ghz Cell processor? That's one of my wet dreams I'd given up long ago.
I never thought the PS3s hypervisor protection would be defeated, so when IBM nixed Cell based PC applications (outside of the sever and PC cards they'd already assisted in developing) I pretty much gave up on these ideas.
Would providing the development team with a PS3 with old enough firmware to be hacked encourage them to test it as a possible port?
