So I got this from eBay, it's clearly a bootleg version of Emerald. It was cheaper than a typical cartridge that could have had a worn out battery or no box/instructions going for some ridiculous price. This saves and plays perfectly fine.

Does anyone know if there's a place to get guaranteed bootlegs? I'd rather buy a bootleg of one of the old games instead of a £20 cartridge from over a decade ago that no longer saves like my Blue, Gold and Yellow games.
