This was the most interesting thing I read today.
I remember the checksum thing from reading about it a while ago, but didn't know that vendors exploited collisions in order to display their own logo.
What I do remember though from childhood days is that the Nintendo logo could gradually become a pixelated mess when the cartridge was dirty/dusted and that it failed (or maybe refused, as I just learned) to boot when the logo was corrupted.
In that case, blowing the dust out of the cartridge usually solved the issue :)
