The developer released a PKG CrashSerious One called for launching any disk Ps1
One can boot all discs, even those reported as non-functional (eg SLUS-01104 NFS: Porsche Unleashed). Running on 3.41 and 3.55, its use is very simple. Install PKG, One and start with a CD in the drive. If you do not have a CD in the drive, a return to the XMB will. It is no competition CrashSerious has not been functional with Multiman, but for the sake of freedom for the user.
