I said I'd keep my eye on this project in the hope that more parts of the game were released to the eager viewing public, and Mochi64 hasn't disappointed. I know the VB wasn't exactly a console that did great or a console that many of us think of with the same kind of fond memories as the SNES or N64, but you've gotta admit that it's a quirky piece of tech and an important console in Nintendo's history.
Mochi64 has been working to bring the seminal N64 game to the Virtual Boy, turning the luscious colours of the original game into a red and black world fit for Ninty's futuristic visor that works on actual Virtual Boy hardware. And it runs in stereo 3D at 50fps.
I have been working on Super Mario 64 for the Virtual Boy 🔴🕶️. Now it runs in stereo 3d at 50fps From the iconic launch screen to king bob-omb everything runs on Virtual Boy hardware. Porting sm64 to vb is much harder than you think: the VB is way too weak to render this live, so every view is ray-traced ahead of time and stored on the cartridge. mario and the enemies are drawn live on top. took me forever to get it smooth lol

Mochi64 has said that 'From the iconic launch screen to King Bob-omb, everything runs on Virtual Boy hardware.' That's all this fan-made demo currently has, though that's not a criticism. Porting to the Virtual Boy can't be an easy task, even if AI is helping you get the job done.
Mochi goes on to say that the Virtual Boy is too weak to render everything live, so every part of the game is ray-traced ahead of time and stored on the cartridge. Then Mario and the enemies you face are drawn live on top.
I've reached out to Mochi64 to ask about the game and how far they're wanting to go with the demo. They've said that they're going to release the demo once they've got a few more levels and stars sorted first.
I try to get it done as much as possible. The limiting factor here is ROM space which is only 16MB. My hunch is that 5 levels is doable but for the complete game I already have a patch for the emulator in order to allow me bigger ROM sizes but for the VB hardware a custom cartridge would be needed for the complete game.
If you have a Virtual Boy and want to play this on your actual hardware, then you'll need a flash cart like the Hyper Boy to load the ROM onto once the demo is live. Keep an eye out here for when SM64 Virtual Boy finally drops!
