My carts are all repros. Boxes too. I don't want someone's old 30-year-old copy of DKC that might not even work plus smells like cigarettes and costs $80.
If where talking discs they do be kinda fragile, but carts are kinda durable very unlikely to get a non functional one.
Heck if anything originals in poor shape prob gonna outlast low to mid quality repro's.
price wise defo trash in terms of originals but than again everdrives emulation etc exists and are reliable + cheaper than buying seperate repro's
