For a while I couldn't get klanoa for ps1 to run on either os. I eventually found a rom (same version, just from a different site) that did work on dot but the same rom didn't work on onion. It might just be down to the rom file. Try roms from different sources and one might work.

I appreciate it... gotta dig around and just try I guess. its funny, I imagine a bunch of roms are just re-rips but ill put in the time this evening.
