Yeah dawg that shits worth like... $100AUD if you replace the internal battery.
I was talking about Fire Red and Leaf Green though, those are worth even more for some reason, like $300AUD
It kind of sucks though. Used retro game carts used to be dirt cheap. I kind of miss getting a shitty old cart and restoring it, you know?
I guess there are always flash carts for the physical media lovers. Thank god for piracy.
