I finally got some retro computers loading correctly in mame but Im having other issues and they appear to be related to the available keyboard overlays. the US-101 keyboard the retroarch menu button doesnt seem to respond as far as I can tell the other ones do, granted I have not tested the F keys. The qwerty and modular-keyboard smalls overlay seem to be bunched up at the bottom of my screen, Im assuming I can edit the cfg to address that but was wondering if there is any guides on it.
Also may be a dumb question for the keyboard overlays with the controller shaped button, what is it supposed to do?
