Hey
what is the cost to make one of those?? Also I am not a big fan of the VMU out the front like some have made...
Also i am not up on DC emulators.. what can it run??

Jim
It's not too expensive.  A bit tricky and time consuming, more than anything.
About $20 for the DC with controllers (craigslist). About $10 for the NES (Value Village).  About $10 for a pair of Genisis extension cables.  Misc wire, solder, copy of NesterDC...
You've got about $50 worth of materials in there.  If you were ever going to try to sell them, I would think you'd need to get $150 to make it worth your while and I doubt anybody would pay $150.
As for the emulators, just ran NesterDC.  Not really sure of any others.  Unless you make some sort of hinged top, there's not a really easy way to get the discs out.  I just put NesterDC in there and left it.
