Went to a shit ton of yard sales today and was able to pick these 3 games up for a total of 15$ seemed like a decent deal and I still think it was. After getting home and checking the games out in my GBA SP. Ruby & Sapphire work, but I get the battery is dead message upon starting to play. Where can I find replacement batteries online? Also is there a tutorial any where on replacing them? Now as for Leaf Green some of the contacts are well worn and I remember seeing silver liquid trace repair online (not sure if they make gold colored). Has anyone ever used that to fixed messed up contacts? I'm pretty sure it would work and don't see any reason why it wouldn't just want / looking for a second opinion. Also at the same yard sale was able to pick up 5 DS games for 10$! It was a really sweet day.
