I managed to flash a black background to 2.71 TA-082 as the january wallpaper!!
I used psp filer 1.5: http://dl.qj.net/PSPFiler-v1.5-PSP-H...9676/catid/190
you will also need the "kreik" eloader (.995) and the original 2.8 xloader, xGSloader uses files from these, so they will be needed.
I am not responsible for any bricks, this worked for me it should work for you. I suggest you flash a background that is not currently being used so if you do screw up, you may be able to fix it.
launch xgs loader for the photo menu, it should say "corrupted data" that means it has launched, you should notice that the xmb doesnt make the clicking noise anymore.
then launch PSP filer from the game menu
change the language of psp filer of you need to (select then "o")
enter " mode" (left shoulder + right on d-pad + right shoulder)
scroll to your background named "01.bmp"
press "x" to bring up the options and then "O" to copy it to ramdisk
press "start" to change directory to flash0
then scroll to flash0:vsh/resource/
you will need to delete the file that you are replacing ("x" then square)
and now highlight the resource folder and copy your background from ramdisk to flash0 ("X" then triangle)
now reboot and check your wallpaper :Jump:
This method could work for gameboots too, but seeing as how you would have to delete it, if something goes wrong, you are screwed. And I havent tested a gameboot.
Good backgrounds can be found here:
gameboots should also work, just use the same method as described above.
if you screw up the gameboot, this is said to work:http://forums.qj.net/f-psp-hacks-9/t...und-71709.html but I cant give any guarantees.
