This is just little guide for you guys out there. You can place the files in your flash0 or build a CTF from them and use them that way, but in this guide I have explained how to put them in flash0.
I AM NOT RESPONSIBLE FOR ANY BRICKS. YOU DECIDE IF YOU WANT TO USE THIS GUIDE OR NOT. IT WORKED FOR ME AND LOADS OF OTHER PEOPLE, THAT'S ALL I CAN SAY.
What you need to download
1.Rename the 405.PBP to EBOOT.PBP and place it to the root of your memory stick.
2.Extract the two folders included in RSPsarDumper 3.5 (PSP, RS) to your memory stick.
3.Start RSPsarDumper 3.5 from the Game menu. Wait for it to load and press Circle to dump the files encrypted.
4.Wait for it to finish and connect your PSP to the PC. Go to X:/DUMP/F0/vsh/resource/ and copy the file visualizer_plugin.rco to your desktop. Go Back and open the folder 'module'. Copy the files visualizer_plugin.prx and music_player.prx to your desktop.
5.Go away from USB Mode on your PSP. Shut it down completely, go to recovery mode and select Advanced->Toggle USB (flash0). Make sure the USB cable is connected and go to Removable Disk->vsh/resource/ and copy the visualizer_plugin.rco from your desktop into this folder. Go Back, and open 'module'. Copy visualizer_plugin.prx and music_player.prx from your desktop into this folder.
6.Select Toggle USB (flash0) again, and go Back->Exit. Your PSP will now restart, and you should have the new visualization(s)!
I do not take credit for the applications you might use in this guide.
