Either it's in the console ROM, in which case it's not a problem, or it's in the cartridge ROM, in which case I'd imagine it's just a matter of replacing the raster data with something else.
- mattl 3y agoYeah demoscene has a few hacks to get around the checks.
- londons_explore 3y agoIt's in the game, but the console famously checks that the code for the logo is present, and refuses to run any game which doesn't have the code in place. It was used as a way to prevent anyone unauthorized making games. If you copy the logo, you have violated trademark and copyright law, and if you don't copy the logo, your game won't run.

- ant6n 3y agoIf I remember correctly, the ROM gets read once to check, and then again to display. One could use some circuitry to deliver another logo on the second read.
- londons_explore 3y agoAlso, a court struck down this approach to locking a console from playing third party games anyway. That's why all modern consoles use digital signatures.
- ClassyJacket 3y agoWhy is it not a problem if it's in the console ROM? How do they get around it?
- einr 3y agoThe idea is that by forcing games to include the trademarked Nintendo logo in the game ROM, an unlicensed dev would be guilty of trademark infringement if they used the logo.
