I have working copies of both Pokemon Blue Version, and Pokemon Yellow Version. Planning to get $20 each, or $35 if you both go to same individual.

　　Blue Version- Saved file near start of video game, prepared to be rebooted, STILL SAVES. Some of the color fading from top of paper label on cartridge, other than that, excellent condition.

　　Yellow Version- Save file near beginning of game, all set to be rebooted STILL SAVES. Very same as with Blue, slight fading beginning at top of paper label on cartridge.

　　Both tested and work fine on my traditional Pokemon edition Gameboy Color, so I would imagine would work simply great on more recent systems too.
