WARNING: We consider this an Expert Level modification for the Nintendo 64. This kit involves soldering directly to the legs of the N64 NUS which requires an advanced level of soldering skills. Meaning only those with significant modding experience should attempt this modification. Stone Age Gamer, nor the manufacturer, will warranty modifications that are not done properly. If you do not feel comfortable installing the 64HD in a Nintendo 64 yourself we highly suggest either using an approved modder (we offer this service for $119.99) bundle the 64HD and install service together HERE.

  • This mod outputs the digital video signal directly from the on-board FPGA. 720p mode is compatible with almost all devices we tested, however, 480p and 1080i are auxiliary modes that may have issues on some devices such as audio or graphical glitches.
  • 240p mode is to be used with non-scaling HDMI to component adapters for CRTs and PVMs. Component adapters that have an internal image scaler will present issues with with 240p mode specifically. Component adapter must also support 480i input, 480p support only does not suffice for 240p mode. These compatible converters seem to be in short supply at the moment, but we will post a link here to a suitable converter when a tested and reliable source is found.
