The listing, Pokemon Sapphire (Authentic, Cleaned, Tested, New Battery) has ended.
English (USA) version of Pokemon Sapphire for Gameboy Advance.
Brand new internal battery installed, cartridge cleaned, contacts polished, and game tested by me personally. So you can be assured that the functionality is as if you'd just pulled this out of the box, brand new. The only downside is that the label is missing. There's a save file on there, but not really anything work keeping on it.
As an added perk, I will ship this within 24 hours of getting your (Listia-verified) shipping address. Happy bidding, friends! :)
