The first model of the Nintendo Entertainment System (NES) has a 10NES lockout chip to prevent unauthorized games from being played which many of the companies worked around. The negative result to the consumer is that this chip caused reliability issues with the system resulting in blank screens. If the chip is disabled manually or by the use of a 3rd party device (blinking light win) then it is much more reliable.

The top loader model of the NES later released removed this chip making it more reliable in that respect. My question is, would disabling or using the BLW violate the DMCA or any other US law?




Considering this appears to be a sort of dongle for an outdated system, chances are that it would fall under a 2010 DMCA exemption. (As described by DMCA section 1201).

  • And it is no DMCA violation without at least attempting to make illegal copies of something. I don’t see anyone attempting to infringe on Nintendo’s copyright. I think Lexmark ran into that problem when they tried to use the DMCA to prevent people from using third party ink in their printers.
