No a N64 keyboard does not exist. You can play N64 games online using an emulator which you then use a keyboard to control, but there is no attachment keyboard for the N64 system. .j.

I am afraid that the .n64save and .n64freeze formats are used only by the propriety n64 emulator for Mac OS X, Sixtytforce. [www.sixtyforce.com]
yes you can with a emulator but keep in mind its illegal
You have to register with sixtyforce to save.
The emulator controls are found on your keyboard, usually there sound be some recognition through the emulator to determine what keys cause what actions. .j.
