Homebrew developer CrashSerious as brought a new application for jailbroken PS3 consoles – ONE v0.1.  This app lets you boot any PSX game disc, even those that reportedly could not run with previous methods.  The only requirements are MFW 3.41/3.55.  Keep in mind ONE will not select load PSX VMC’s, and furthermore does not support loading from a HDD.

Installation Instructions:

• Download the archive
• Install the pkg
• Simply insert your PSX cd and run.

Download: ONE v0.1 (677kb)
