Notes on converting a cabinet
During the arcade's heyday, it was common for an original arcade cabinet to be converted for use as another game as the older game waned in popularity and a new game took its place.
This makes it more difficult to find the original cabinet in its true form and many arcade cabinets are now very rare and are considered to be valuable collectors items. Because of this, you might not want to convert your existing machine to a MAME cabinet (this process is also known as MAMEing a cabinet).
However, if you've got a cabinet that's fairly new and not considered rare, or an older cabinet that's been converted many times and bears little resemblance to its original, it's perfectly acceptable to MAME it without harming your conscience. If you MAME a rare cab the RGVAC police will find you!
