HOW TO...

It is very simple. First, get N-Rage's plugin from >> HERE << (Remember, we want 1.82a).



IMPORTANT NOTES BEFORE READING

It's been 6 years since I wrote this guide and due to popular demand, it's time for an update.

Get version 1.82a, since the latest version (1.83) won't load the savegame correctly or it's somehow broken. Simply, IT WON'T WORK, saying "Saved file not found".
This method works with both Pokemon Stadium and Pokemon Stadium 2.
N-Rage's DirectInput plugin requires DirectX 8 or later to work. It is always important to have the latest DirectX version installed in your system.
THE GAME BOY TOWER DOES NOT WORK! PERIOD!!!
This method has been tested in both Project64 1.6 and 1.7 and with different regional Pokemon Stadium ROMs (mainly U and E ROMs). They were also tested running on Microsoft Windows 7 Ultimate 64-bit operative systemStep 1 - Selecting the plugin that supports Transfer Pak.

In Project64, go to Options --> Settings (or simply press Ctrl + T).
Now select the N-Rage`s Direct-Input8 V2 1.82a plugin. It's the best one that supports Transfer Pak.

Step 2 - Configuring The Controller Plugin.

Go to Options --> Configure Controller Plugin.
Select Controller Pak tab.
Select Transfer Pak from the drop down menu and select the GBC and SAV files in the two last fields and click Save. Make sure RawData is enabled as well.
Run Pokemon Stadium 1 & 2 and play with your well trained Pokemon from the Game Boy games.
