Fastmame - alternate key configurations not loading

[D5A1AC]

A while ago I was pretty sure that when I redefined the keys in mame (not the global settings, the game specific settings), they would stay redefined even after I close and reopen mame. Now the controls revert to their default settings each time I reopen mame.

Am I an idiot, and they reverted back the whole time or is there a solution to this? I am using fastmame 0.98. If they do revert back, how do I go about redefining the controls for specific games permanently?


I'm sure that it used to save the new key configuration.... 

Thanks for the help.
