Nintendo 64
The original Rumble Pak, designed for the Nintendo 64 controller, was released in April 1997 in Japan, July 1997 in North America, and October 1997 in Europe. It requires two AAA batteries and is inserted into the controller's memory cartridge slot, which prevents simultaneous use of the Controller Pak. This usually has little impact, as Nintendo 64 games are cartridge based and have the ability to store saved data in the cartridge, but for games that support the Controller Pak, it is possible to switch between accessories at certain points, a method known as "hot swapping".
The Rumble Pak was introduced bundled with the game Star Fox 64 (known as Lylat Wars in the PAL region) and made available as a separate purchase two months later. Rumble Pak support soon became a standard for N64 games. Launch titles Wave Race 64 and Super Mario 64 were re-released in Japan in July 1997 with Rumble Pak support.
Several thirdparty versions of the Rumble Pak, such as the Tremor Pak, followed. Some draw power from the controller instead of batteries, but the lower power makes them less effective. The TremorPak Plus allows a memory card to be inserted simultaneously, eliminating the need to switch between two accessories. The Nyko Hyper Pak Plus contains internal memory and allows the user to adjust the amount of feedback between "hard" and "too hard".
