N64 game Pak

Verify that only licensed accessories are being used with the system. Unlicensed products are not fully compatible with Nintendo systems, and may not work correctly.

Check the game pak manual or packaging to verify that the game is designed to be used with the N64 Transfer Pak.

Make sure the Game Boy game pak works properly in a Game Boy system. It may be a problem with the Game Boy game pak and not the Transfer Pak.

Verify that the game paks are inserted in both the control deck and the N64 Transfer Pak. If they are not, insert them and then turn the control deck power off and back on again.

Verify that the controller is plugged into the proper controller socket on the front of the control deck. If it is not, secure it and then press reset on your control deck.

Remove and re-insert the N64 Transfer Pak, making sure the pak is fully inserted into the bottom of the controller. If it is not, secure it and then press reset on the control deck.

If possible, try another controller. If the Transfer Pak works in another controller, it may be the controller that is having a problem. Check out controller troubleshooting (click here).

If the issue persists, the Transfer Pak may need to be replaced. For information on locating replacements for older products, please click here.

Well it means that the game pack was not made to work on this console at the time it is not companle with Pokemon yellow so you could try and see if it will work on a wii or wii u console. If it works with the game boy advance sp then that's fine for that system then not for the N64 console sorry Pokemon stadium 2 was not made at that time.

I will refer you to a page on Wikipedia that explains it -- but the simple explanation is that the Nintendo 64 Expansion Pack increases the RAM on the N64 from 4MB to 8MB. There were a few games with improved graphics and game play that REQUIRED the expansion pack.

Yes you can remove the Expansion Pak from one N64 and put it into another. However, your N64 will NOT work without either the Expansion Pak or the Jumper Pak in that slot. The original memory card that came in there was called the Jumper Pak which was 4MB. The Expansion Pak was 8MB.

I think that you need to have an expansion pack instead of using the jumper pack.

Plug an N64 controller into the "Player 1" port on the Nintendo 64.

2 Place the N64 Controller Pack into the memory card slot on the Nintendo 64 controller.

3 Insert a Nintendo 64 game into the cartridge slot on the N64.

4 Hold down "Start" on the N64 controller.

5 Turn the Nintendo 64 on via the "Power" switch on the device. After the console loads, the Controller Pack menu will appear on the screen.

6 Release the "Start" button on the N64 controller.

7 Browse through the saves listed, using the N64 controller's directional pad.

8 Highlight the game you want to erase.

9 Select the "Delete" option. The pages that were occupied by the game save will be erased from the Controller Pack.

10 Repeat Steps 7 though 9 until you're finished erasing pages on the Controller Pak. Restart the N64 if you wish to play the game that was inserted into the device, or turn the Nintendo 64 off if you are done using the console.

Try cleaing the contacts on the games and the transfer pak itself, look up how to clean games on youtube.

Its most likely the controller. When you put in the pack is it loose? You could try cleaning the GB game and trying again.

You dont actually save it to the gamepak (n64 memory card) it gets saved to the n64 cartridge via a transfer pack that plugs into where the memory goes into the controller then you can import your save with pokemon stadium into the n64 gamepack.

The battery inside the game pak has died, thus, it can no longer hold a save.
Buy a special screwdriver for n64 Game Paks. Unscrew the casing, then find the battery inside the Pak. Take it (the battery) to any store that sells watches, then ask for a replacement for that battery. Plug the batery (+ side facing you) in the Pak, then screw it back together.

Your game should now save. :)
