i want to change the loading screen

i want to change the loading screen and sound . i cant find any loading screens for 3.71M33-4. if ne1 has a link and instructions on how to flash the files onto my psp that'd be great. i have a custom theme vista with custom waves all i need is the loading screen. i know it changes by the theme but i want the individual loading screen. any info on how to create load screens or where to just find premade ones would be awesome. Thanks

hey can no one here answer this question

Last I heard, the loading screens use some utils that are illegal, so sites like this can't/won't post links to them.

O_o And loading screens haven't been to popular since CFWs came out. I haven't heard about them in a long time..

you mean you want to change the gameboot? as in the white screen with psp written on it, thats easy enough google psp gameboots, download one, overwrite the gmaeboot.pmf file in your flash 0 then its done. (backup your flash before hand though obv)

ok cool thanks. do they have to be be formated to run on certain firmwares?

Nope. The file's the same on all firmwares.
