I have finished the first version of the PiMAME installer. This will allow you to install PiMAME, the ftp server, webserver, and other additions with just one script.
You can also completely uninstall it and update PiMAME with one command, so no more downloading new image files.
The script is available here: https://github.com/ssilverm/pimame_installer
I would love your feedback, comments, suggestions, pull requests, help, etc.
