The PS3 is very different from the PSP, sorry.
They probably have already addressed the exploit in TIFF images in the PS3, plus there is differences in the hardware capabilities and software itself.
Why would you wanna homebrew on the PS3? I'd rather play Super Mario World on the go, I already have a SNES for it at home.
if i had a PS3. i would want to run homebrew because of the "Just because i can" factor
on topic: i could have sworn i saw a post stating that the HEN would be released at noon GMT? (2 hours ago)
