I think that they are a double edged sword in the market. Its probably better if people buy flash memory carts to play games on their system that never got released in their country and language , but sometimes its nice to have the convience of a repro cart granted if its not to expensive I have a star ocean , sweet home and ff 3 nes cart myself. But yeah the dubious stuff is making repros of things that were originally released in the states. Like if you go to reddit/r/snes so many people get dupped into purchasing fake earthbounds thats its hilarious and sad at the same time. They are a good service for titles that never got released its good for playing purpose but I understand where your coming from I dont think they should be treated like collector items at all. Its like purchasing a original vhs tape over a bootleg copy of the original released tape.
