my idea for 2.5 downgrader

Ok here it goes download the 2.0 downgrader and rename the overflow.tiff to ICON0.tiff and put it in a saved game icon instead of the original. The load the umd game and when you come to pick your saved file in the game it should overflow because the picture is loaded in the game and not from the firmware.

AFAIK sony patched the buffer overflow problem with tiff support in 2.5. I might be wrong though.

It was patched in 2.01 and the code carried on over into 2.5.

I wish sony would stop worrying about homebrew and pay more attention to new features.

They're not worried about homebrew, they are worried about piracy and code flaws in order to maintain maximum a$$ coverage in the event of a lawsuit from a consumer group.
And firmware programmers do not want to have "created easily exploited firmware" on their resumes as it tends to limit the jobs they can get to ZERO.
