This is the thread dedicated to the collecting of all things under the label of Gameboy (OG, Color and Advance). We have a thread dedicated to SNES and Genesis but there's also a market for these games so it's time we started up a thread dedicated to them. Feel free to share your stories, your finds and any sales you think people would be interested in, let's help each other out!

Check your local thrift stores, pawn stores, flea markets and even Craigslist. Gameboy games tend to be overlooked by collector's so you can usually find a lot of good stuff for cheap. Helps to take along a system so you can try stuff out too!
Educate yourself about fakes! The GBA is rife with counterfeit copies and you would be wise to find out what the real thing looks like!
If you have the tools, find tutorials on replacing batteries. Some of the games like the GBC Pokemon games are notorious for batteries going bad and many a save has been lost because of it!
If you're curious about the value of a game, you can always try the completed listings on ebay or try this site out:
