Ookm has updated his HEN AutoExec Mod so that it does not flash red when you turn your PSP on.
Now it only turns the screen blue.

You can read about it here:

And you can download this from here: http://rapidshare.de/files/36662684/...v0.01.zip.html

Remember this could brick your PSP, use with caution.
