I live in Indonesia, in the 90s and 2000s, most of the games that were sold in the market were bootleg copies. it's just recently that we could actually *gasp* afford to buy original software thanks to increasing wage and such. However, it's very hard to find genuine retro games in the market. While e-commerce is booming and a lot of people are now selling their retro consoles and games, a lot of nintendo games are bootlegs and sold at cheap price. Should I buy them or they are actually worthless (for collectors purpose)?
