Folks on this site likely know the feeling; You and three 'friends' are in a heated Super Smash Bros. Melee when someone cries out, "My "R" button isn't working! Hey guys, wait!" Or that heated Joust versus match with the controller that just doesn't 'flap' as fast, or the time you were excited to show off your rare Sega CD Snatcher on one of the four days of the week that the drive tray doesn't want to work...
If you are a retro gamer that plays as well as collects, you know the effort it takes to upkeep your library. Vintage video game collecting is like classic car collecting or pinball machine collecting; it's more than just having space for the stuff and the ability to find and pay for the games and hardware. If it is going to remain playable, there's some know-how and some elbow grease that will become part of the hobby. From notorious controller wear and faulty optical drives, to analog drift and bad capacitors, every retro player/collector has to get comfortable with just how far down the rabbit hole they are going to go. Perhaps you are fortunate enough to have a passion for a console that seems immune to all but psyonic attacks (SNES, Game Boy Color) or maybe you've fallen for a glass snowflake (Famicom Disc System, a Turbo Duo with good sound), but either way there is always some basic maintenance needed.
