The 64DD was a Japan-only disk-drive peripheral for the Nintendo 64 that allowed memory expansion, Internet connectivity via Randnet, and increased game storage capacity in addition to allowing games to be sold on magnetic disks. For various reasons, the 64DD was a market failure and plans to release it outside Japan were scrapped.

To do: An American prototype 64DD has been found (see this video from the person who found it) and dumped. Analyze the code, there might be something interesting.

Unreferenced Animation

There are three duplicate one-frame animations of Mario that are unreferenced: two standing, one crouching. To view these in ipl4prom from the iQue N64 SDK (CRC32ː BF7DDAEB), replace the value at 0x34B34 with 80283E20 (standing 1), 8028455C (standing 2), or 80288410 (crouching). This will replace the running animation after Mario kicks the "N" logo.
