I just switched out the batteries in all my gameboy games and figured I could put my pokémon crystal game into the cartridge of my pokémon trading card game and make some prototypy label for it

here's the result - I like it :)

what do you guys think ?

also - remember to switch out those batteries in time, since you don't want your savegames to vanish into oblivion (trade the pkmn onto an other game first of course)
