You've already had a taste of the fake, one-of-a-kind game cartridges on display at Japanese indie Meteor. Now have a look at the event itself.
As previously posted, the goal of the exhibition is simple: artists submit a cartridge for a fake Famicom game. It can be whatever they want, basically, meaning some can be funny, and others can be super stylish. Submissions are taken from all over the planet, not just Japan.
