I was looking at various emulators yesterday and stumbled across some LinApple pre-built binaries. LinApple is an Apple][ emulator which I think might be in Chameleon Pi too. Not sure though as I have never used it. How well would this work in PiMAME? Here is a download link: https://db.tt/4yruAVLh You will have to chmod +x the binary. I haven't tested it yet though, sorry.
