I will tell you something very interesting I found today after I upgraded my PSP firmware from 2.60 to 2.81.
All my homebrew worked on my 2.60 with eloader 0.99. I just bought Metal Gear Solid Portable Ops yesterday. it wouldn't let me play it till I updated. Well I was stupid enough to update it. I knew about devhook, but somehow I forgot to download it to my psp.
Way later, I spent about a few hours searching the net, found that the tiff exploit was patched to 2.81 firmware. I was mad afterwards, but soon enough I figured something out that could give Fanjita a way to make eloader work on 2.81
I'm very good with computer skills, know my way around many programs. it doesn't take me long to get the hang of a new program.
Before going any farther, I only suggest the N00bz! (eloader creator) or Fanjita to experiment with this.
1. Instead of focusing on tiff images, why not do that with psp video instead of images. I found something quite interesting that the video files are a lot easier to trick than doing this with tiff images.
2. Hack in the "reboot.bin" 2.81 firmware version.
3. Hack in the file that has the fixed tiff security hole.
--ONLY FOR NOOBZ and Fanjita to work on. people that do not have experience with this do not try this--
