I think it has to do with THE fact that this is building your own arcade forum
This is actually the Restoration portion of this forum, hence the 300+ posts of restoration projects listed here. Building a mame cabinet is great, and a good way to play everything, but it doesn't beat having an original of your favourite game.
Restoration plays a major role in the whole point of Mame/BYOAC, which is
preservation, and should not be looked passed.
Lots of contributors to this site have more than just a mame cabinet, many of them have originals as well. Also, a lot of skills learned from restorations can be applicable to building/converting a mame cabinet.
Heh, even lots of people that start off in Mame cabinet building end up becoming collectors. So there's no need for the elitism. It's all in the same family.
I've just started the vintage repairing part myself maybe one year ago, so I know next to nothing on repairing them (so far). Built my MAME cab about 6 years ago (and it still needs touching up and improvements ) I feel building can and should mean both MAMEING and preserving. But a good machine like it sounds like you have I think should be restored.
Absolutely.
To the OP, I haven't seen anyone restore an Area 51 before, so this would probably be a first. Is it an original cabinet, or a conversion? An original could be a fun project to restore...
