Item description:

Pokemon Stadium (N64) save file with 100% completion. This save file is for use exclusively with recent Mupen64Plus Next emulators, or the same core in RetroArch.
All Cups beaten (Round 1 & Round 2)
Gym Leader Castle beaten (R1 & R2)
Hyper Difficulty in Kid's Club unlocked
Mewtwo defeated in both R1 & R2
Doduo and Dodrio GameBoys unlocked
All 151 Pokemon registered in Hall of Fame
Amnesia Psyduck unlocked and waiting to be claimed at Prof. Oak's Lab.
All other unlockable Pokemon could be obtained by repeatedly beating the Elite Four on the Hall of Fame.
I couldn't have them all since the game only allows for one Pokemon at a time to be held by Prof. Oak, and I went for the most important one (Amnesia Psyduck).
