(The shortcut appears in the same folder as the main exe after opening the main exe once.) Click on the box under ISO/PBP File and select the appropriate file to combine discs.

Although it seems it only works if you open 'classic mode'. You can also merge multi disc games into the same eboot which is another way to fix the save file conflict. A folder with the game id is created in your output folder with the eboot in it. Now you're ready to convert so go back to Convert Menu and press convert. I'd just change ICON0 but you can add other pics too. Here you can change things like ICON0 (xmb icon), PIC1 (background or wallpaper), and PIC0 (info about the game). Otherwise the save from disc 1 won't be read by the other discs. The game id and save id must be the same for all the discs of the game.

I just chose the desktop but you can choose anything. Then choose your output folder by clicking the box under Output PBP folder. I'm using Final Fantasy 9 because it's a muti disc game and the saves are a little complicated with multi disc games. Then under ISO/PBP File, click the box to open your iso file. Now open the program and click on convert menu. Not every ps1 game box art is in this folder but most are. You can find them under PSX2PSP_v1.4.2/Pics/ICON0.

Someone else did and uploaded them to this site. I took the liberty of putting a bunch of images of the ps1 game box art. So you ripped your ps1 game from your disc/discs but how do you play it on your psp now? You need to convert it to an eboot for the psp to read it. I was suprised when i didn't see this tutorial for converting your ps1 isos to eboots so here we go.
