The prototype is available as a ROM file, but I'm not sure if such a leaked prototype of a game is illegal to link. So I only link to gameplay footage.

I can also recommend following historical documentation video series from 2024 by The Obsessive Gamer. Each video about 23 minutes. They document cut content and history how the game was developed first on Super Nintendo as Project Dream, which later became Banjo Kazooie on Nintendo 64:

Today, I’m releasing the SNES proof-of-concept alpha of Project Dream, the proto-type that would go on to become Banjo-Kazooie.

I’ve held on to this for years, it was fun to have something that only a handful of people had, and as I am several people removed from how it got out of Rare to begin with, I didn’t want to risk that it could somehow get someone else in trouble, (so how I got it is a story I don’t plan to share.) I will just say that I got it from someone who got it from someone, who got it from somewhere.

But with the current state of the industry and Microsoft's current heartless gutting and mismanagement of Rare and other companies it controls, plus with how long it's been, I feel it's more important to make sure this is properly preserved, and the ROM dissected by people with far more knowledge on how to do such things.

I hope by releasing this, that it also inspires other people to release what they have as well. I know the Twelve Tales Conker 64 prototype is out there somewhere, but sadly, this is the only thing that I have.

There is little joy left in the industry, as it relentlessly marches towards AI, layoffs, l anti-preservation and ownership tactics, and, in Microsoft’s case, the support and approval of literal genocide in Gaza.

Let’s get the last beautiful things hiding on our hard drives out there for everyone. That's all we have left.

Please delete Microsoft and Sony from your lives, install Linux, boycott Switch Game Key Cards and buy Nintendo Switch 2 titles that still come with the full game on the cartridge. Your dollar is the only thing that counts in our late stage capitalist hellscape.

The attached zip contains a .bin file of the raw dump, and then the same file renamed to a .sfc to work in emulators, as well as this text file.

If any game journalists choose to report on this prototype release, I would ask they kindly include the full contents of this text file as courtesy to me for finally getting this out to you all.

Be blessed, and love each other.
