Aren't save states version dependent?

If you want me to stop making changes to the code, then yes, let's enable it. Otherwise, I need to be able to make a change to the code and still load a savestate for testing.

Up to you. Halt development and allow people to go nuts using unstable versions that we warn them are unstable, or continue development and live with the fact that you can get a crash if you're using unstable versions of the emulator and playing with savestates between versions.
