I was wondering if someone could help establishing what is the general main cause of problems between cartridge games and the systems. Someone here is selling a large box of games with a Megadrive II for a very reasonable price. When I asked the condition of the system they said it works well but you have to blow on the cartridges a lot and it got me thinking what actually causes this issue and is there an easy method to clean what is causing thsi from general household items?
To be honest the price is worth it and just to get rid of the Megadrive if it dosent work but if this problems is caused more by the games itself it might not be worth it.
