What if you used Mame to emulate PC-10, and used PC-10 to coin-up.
Thanks for the info.

I think that would be great, except I wouldnt be able to coin up and play NES games like Zelda. The appeal of the PC10 was being able to use an NES flash card to play all the non PC10 games like Zelda, etc.
I think Im slowly accepting the fact that I wont be coining up and this is going to be a PC build. It seems to be the general consensus as far as the best way to do it, so I will listen to the advice here and roll with it. Anyway, the FIFJ cabs Disney built dont coin up, so I guess this one doesnt need to either.
On my other Nintendo builds I do have coin mechs, but I have yet to use them. I just hit a coin up button under the speaker panel. I just thought the option of coining up was cool....but I can live without it. So PC it is. Thanks guys.
P.S. Yotsuya, that would be cool. We take the 80 across Wyoming and through Utah into Idaho. Avoid Wyoming if you can. (and before anybody from Wyoming says anything, Im UW alumni and lived through the frigid 10 month long winters....so I think Ive earned the right to talk trash) Haha.
