I've recently ported Daedalus to PS2 just to see how it would perform. With dynarec enabled and without sound you can get around 20 - 30 fps in Mario 64. With optimization like using vu0 for matrices/vertices calculation, move renderer on vu1, sound on iop and should be more. But I still have problem with distorted graphics, hard to find what may cause that.
Usage of PoC Port for PS2:
Put files/folders (of download) on root directory of mass,
looks for roms in 'Roms' directory.
Reported Games (click title for user report) boots / doesn't boot
