A new homebrew application by coder SuperFury1 has just been released. The EBOOT2ISO, once installed, will allow you to convert your PBP files to ISO on a specified directory folder.

This application (for the PC) will let you type your destination directory. After doing so, just press “convert” and the software will make a PSP ISO directory structure with your EBOOT.PBP’s files in the directory you specify. But before the application allows you to continue, make sure that the directory you have specified has been created already.

After using this app, go to the PSP_GAME directory created in your directory to make yourself a PSP ISO file. According to the coder, this has been tested through UMDGen using 4.0 build 61205.01.
