Play PSX Games not bootable from Multiman
If you hadn't noticed, some PSX games don't appear in Multiman's XMMB and are marked as data discs and will not boot. If you load this (Breaker Pro Loader
) up from the XMMB and then select the main option in the loader, you will be prompted to eject the Breaker Pro Loader disc and to insert your PSX backup. After you put the PSX backup of your choice into your PS3, press any button on the controller and voila! The game which wouldn't boot before and wasn't even being detected by Multiman, will now boot perfectly. Also save files will work with this method as well...just make sure (if using with the ps3) that you create the virtual memory cards prior to booting up Multiman.
