That’s cool!

I picked up a copy of your book, PSP Hacks,” at the Makers Faire in Austin last weekend. I sat down and started to walk through the different hack you’ve listed. I haven’t been quite brave enough to disassemble my PSP yet, but I’m working up to it.

I tried downloading the MPHDowngrader file from chez.com. As soon as I unzipped it, my anti-virus software quarintened it - seems the overflow.tif file has a Trojan.PSPBrick embedded in it. Did you run into that when you were downgrading yours?

Thanks again for a great book.

Ooooh, that’s nasty. No, I did not encounter that when I downgraded, so my guess is the original file has been screwed with. Be careful.
