Quoted from Friengineer:It all depends on the collector. Do you want a mint copy of the original? Then prepare to shell out cash money. If you are tech savy, you can build your own ROM cartridge & have 100s of games. Most people just want the classics anyways like Super Mario World or NBA Jam.
Anyone have a cheap copy of Mega Man X2 collecting dust?
I do, but it's not collecting dust
I think if you are making repro labels they should be marked as such. All it takes is one person in the chain of ownership to either purposely or accidentally not let the buyer know it is a repro and someone gets hosed. IMO it's really not cool to make repros that look identical to the original.
