I want to know the diddy kong racing key code for pokemon stadium 1 and 2

Rom? Are you using an emulator? And by joypad I assume you mean the stick; Pokemon Stadium uses the D-pad.

Set it to diddy. Can't remember the rest, but just scroll through it all and find one that says diddy, and it works.

You want a completely different game code for a completely seperate game? Hmmmmmmmmmmmm?

Eleborate on your question more clearly please, do you want Diddy Kong Racing codes or Pokemon Stadium 1 & 2 codes? Then I'll come back and help you.

Hope this helps

set it to diddy/1080

I hurd it's the same as the diddy kong key code but you shouldn't take my advise yet. Google it and find it out cause that is waht i'm doing. but if your sure your confident, and you want to give it a try, go for it. most likely it might be it

set the keycode to diddy/1080

HERE IS A WALKTHROUGH HOPE IT HELPS A LITTLE

Try to download a different Pokemon Stadium 2 ROM to be sure the ROM isn't corrupted. Also try a different N64 emulator and see if it plays better in another N64 emulator. Either way you'll know either the ROM is good or if the emulator is faulty.
