Here is a "How to" if you want to convert a already converted game(eboot.pbp en ev keys.bin) ,
or a PS1 back-up game(.iso, .img, .cue, ..)
For PS1 back-up games, all steps are the same except for "recompress" wich you do not use!

If you have 3.03oeb you use popstation gui 2,26
If you have 3.03oec 3.10oe etc. you use Zingaburga's Popstaion Gui 3.00

-Download one of my Eboot Packs  voor the game you have.
-(Unpack: -WinRar save somewhere on your computer.)
-Start ZinGaBurga Popstaion Gui
-Load the Eboot.pbp OR an .iso/.cue/.img files.
-Click Recompress,(Only when you use anEboot.pbp file)
-Put compress to 5.(It compresses the new Eboot for more space on your Mem Stick)
-OUTPUT Folder: Create a new folder with name of the game.
-Select "Game ID" From the list(game_title)

-If you have 3.10oe+(and its popstation)you do not need the NTSC patch.
-If you have 3.03oeb(and its popstation) you click "Pal to NTSC" patch.

-And now: click "Customize the Eboot"
-And first of all unclick: SND.at3(You do not need these)!!
-Now you can add my files wich you saved somewhere on your computer:ICON0.png, PIC1.png, ICON1.pmf, gameboot.png
-(Click op Preview)

En click on "GO"

Did you use ZiNgABuRgA's Popstaion Gui 2.26 then you have eboot.pbp and keys.bin
Did you use ZiNgABuRgA's Popstation Gui 3.00 then you only have eboot.pbp

The eboot.pbp "and/or not" keys.bin files are paced in a folder(name of the game)
And that folder goes in :/psp/game on your memory stick

That's it
