Really impressive collection. A lot of people ask me how to get a hold of the older repros, and this might be the only way (someone getting out of collecting). 2 boxed soft-case covers, is very impressive. Hard to get 1, let alone 2. The low number employee vboys, the Japanese kiosk. Someone will end up being very happy.
yes, you can switch them out. There are screws you can remove to do it. I’d recommend just changing out the ribbon cables and eye shade of the main unit.
It would be a hard choice on how to sell. You’d get more money normally by piecing the collection out, but it will take more time and hard to get rid of some of the lesser items.
You might want to post on nintendoage, there might be someone there that would want an ‘instant collection’.
