>retroarch with the FBneo core, with savestates and be as perfectly accurate as it could be
Have tested that and it works. Although I'm not sure about how accurate it is there, but save states are always supported by RA.
As for the PS2 version, PCSX2 also supports savestates but that's not relevant when the port has stage select with a lot more customization than what you can achieve through states.

It's indeed DOJ.
