if you just want a backup why not pack the files into a .zip or .rar file that any burning software / optical drive will recognize and handle then use a image mounting application (like Daemon Tools) to run them whenever you decide to use the games? since...

i really don't think it's actually possible to download a ps1 game image, burn it, then slap it into an actual ps1 and play the game. you'd likely need to use an emulator on your pc to get any use from those downloads. so how they're actually stored on a disc is rather irrelevant. i used to use ePSXe years ago, it was a hassle to setup but once you found all the necessary files (the emulator itself is legal, the necessary ps1 BIOS files are not) it was pretty solid.
