Having first thought MAME OSX wouldn't work with 10.9 Mavericks I went ahead an installed SDL-MAME which worked fine. However, the GUI front-ends I've tried were all pretty disappointing. So I tried installing MAME OSX and it too worked! Although it's nothing like the (now abandoned?) MacMAME (which doesn't work with Mavericks, probably because I believe it's a PPC version and rosetta isn't a part of Mavericks) it's probably the most elegant solution on the OSX platform, but I digress I want to know if it's possible to rearrange some of the keyboard shortcuts in MAME OSX? I suppose something can be edited in one of the config files? Specifically I would like some (all perhaps) of the F-key shortcuts to be placed somewhere else since I'm running it on a Macbook Pro where several of the F-keys are already pre-defined for other things (such as F-12 which turns up the audio volume but takes a screenshot in MAME). Maybe SHIFT along with the F-key shortcuts would solve the problem.
