When I list them, I say untested but were stored properly and in good condition. .99 starting bid, $3 shipping. Sell seperate. You'll do better that way. Mostly they will work, all you have to do blow on them! Lol.
You may want to check on selling the three Castlevania's together. It's a popular series and sometimes people will pay more for them together. I'd check a few completed listings and judge from there.
These carts typically do not go bad so listing as untested will not greatly affect your return.
I have to get my NES's listed ... I have three units sitting down in the basement!!!
Nice Sale. The castlevania series is very popular.
We have a lot of old game systems sitting around my house ready to be tested.
Probably close to 10 NESs.
If you want to up the chances of them working for the buyer - clean the contacts with a cotton swap and isopropyl alcohol. Use a pretty good bit of pressure. On older games that top layer of oxidation is usually the only problem.
