Getting off topic here... but I have mixed feelings. I got a Centipede cabinet, that had been converted to a Double Dragon. Cabinet itself was very solid, no water damage. But it had been sanded on one side (partially), and painted over. The sideart was basically not worth recovering because of all the sanding.The C.P. had been heavily drilled through (agh!). No Marquee, no bezel, no coindoor. I was going to have to spend a fortune to restore this thing.
So I originally decided to MAME it, and began building a control panel. But halfway through the process I started realizing it was quite a restorable cab after all. I re-sanded, primed, bought a marquee, coin door, bought sideart, and so on.
But I already had partially 'commited' to MAMEing the cab, since I bought the dedicated PC, the TV, and built the control panel (a *very* complicated c.p at that).
In the end, it turned out real nice, and the cab is 100% restorable to a Centipede original (i.e. it is possible to revert to original state, because no noticeable physical alteration was made to MAME it).
I can relate to people's rage when they see a classic cab bastardized. I'm actually glad I partially restored it. Also very glad it is a MAME machine. 4000 games vs 1. Thats VERY hard to let go of. Like everything in life, it is a matter of finding some balance. Just my 2c.
