Yes, ePSXe is commercial quality. Hell it even runs faster with the OpenGL plugin then Bleem! does on software mode.
- But I don't think the ePSXe would sell ePSXe, they are too cool for that. I wonder what would happen if you e-mailed sony about specs for the PSX to create an emulator. (I know you can find them everywhere, but just wondering what the big 'S' would say.)
