Well, not to leave out the people with a TA-082 mother board, I've made this. A simple gameboot.pmf flasher for 2.6ers(there's confirms of this working on 2.5 as well)! based off the work of hitchikr, neural, DarK_AleX, Yoshihiro, and Mathieulh.
Just simply put the gameboot.pmf in the root of your memorystick, run the program, and it'll flash it directly to your flash0:/vsh/resources/ folder.
Incase you're wondering what a gameboot.pmf is, well it's basically that little start up video whenever you run a UMD. You can use this program to change that little video to be something else.
Some people may have noticed an opening_plugin.rco flasher and a topmenu_plugin.rco flasher; well those were based off my program here, I just didn't have a chance to release the original yet ;)
* There's always a risk of bricking your psp while flashing something. Although this has been tested and confirmed working; you are using this at your own risk. I am not the one to be held responsible if infact you do brick your psp while using this software.
* I'm not 100% sure on this one, but I believe the MAX gameboot.pmf size is 1mb. Please avoid flashing gameboots that are any larger. If you flash anything larger than 1 mb, you may end up with a brick.
* Thanks to TMK for the idea, and for helping me test it ;)
So here you have it,
