I am finally ready, I would like any advice I can get on building a groovymame setup for my Arcade. Hoping there is a ready image out there, all help is appreciated!
welcome! I was in this same place a few years back. Then I caught the genuine hardware bug. But anyway.
This is an awesome article from retroRGB that breaks it all down. One of the things I particularly like about groovyarcade was being able to boot from CDs/usb to test it all out before committing https://www.retrorgb.com/groovyarcade-introduction.html
