Schtruck, I've seen several complaints about save state not working after updates. How important is it to have fpse using the exact same settings?
Would it be worthwhile to change the format of savestate files? Encode the fpse configuration into the save state and have fpse check to ensure the configuration is the same he fire loading, and if it's different warn people that the configuration is different? The save stats do that a little now, like for Spu settings, but maybe it should do a more thorough check? The savestate would need to be able to support the current savestate format and the new format both.
