Also from USB, unfortunately it's only USB 1.1 so titles with FMV sequence tend to stutter, so for slim models the network SMB share it's preferred...

About PS1 titles, there is a Sony PS1 emulator for PS2 called POPS that you can use with OPL but from what I read it has not a wide compatibility and it's not officially distributed by Sony, the other option is to use mechapwn to boot PS1 CDs, but it doesn't work on the early PS2 models according to this: https://github.com/MechaResearch/MechaPwn?tab=readme-ov-file...

I played around with POPS and PS2PSXe, compatibility and performance was pretty bad on both for differing reasons.

Mechapwn worked for me.
