I too have a Cecha01PS3 and have no issue playing PS2 physical copies of SF Anniversary Collection, SF Alpha Anthology, CvS 2, or NG Battle Coliseum on it. Also PS1 physical copies of SF Puzzle Fighter 2 Turbo, Pocket Fighter, and CvS 1 are cool too.
Probably some other games I can test, but for sure the above have been played with no drama in the last 6 months.
Just plug in the joystick and go.
@Husser_Brian HitBox Multi-Console (Akishop PS360+ in it).
Custom Arcadestick (PC/PS3 MC Cthulhu in it)
Nubytech SF 15th Anniversary Fightpad + PS2 to PS3 adapter (I can get the name of the adapter tonight.)
Nubytech SF 15th Anniversary Arcadestick + PS2 to PS3 adapter (I can get the name of the adapter tonight.)

I just got a PS3 MadCatz TE that I haven’t used yet.
@silvercool2k let me know if there’s anything you want me to try to get this figured out for you.
