One of the neat things about Excitebike is that you get to design and race on your own tracks,

but a few options on that screen confused me, like "SAVE" and "LOAD". You hit one and you get a screen like something's happening

but it kind of gets stuck there. For a long time I thought I had a bad cartridge or something, but it turns out that in the American version of this game, saving isn't even implemented!

So don't be fooled.
