Hey I'm the one who made this, if anyone is interested in the specifics I'm happy to go into details!

Also as another comment indicates probably a better explanation of the project is the video I made about it: https://youtu.be/zXPiqk0-zDY

A friend sent me the YouTube video, which is a fantastic watch: https://www.youtube.com/watch?v=zXPiqk0-zDY.

Minecraft computers have been done for a while now, but seeing a full RISC-V computer running programs is really impressive, and frankly just seems really cool. The programs are written in Rust, and then compiled to run in game. Plus, the author needed to write their own mod to make the Terraria wiring efficient enough to support the computer: https://github.com/misprit7/WireHead

Holy shit! Game, optimizations, code, test suite and even a simple 3D render - not to mention a well edited video game with a great sense of humor, gags, memes and the obvious next step already in the works.

This guy is going places!!

Now we need a terraria build for RISC, so we can play terraria in terraria

Tbh, the video was better explained than my college computer architecture lessons

Fully compliant to RISC-V how? Is it conforming to a specific RVI profile? The project states "By emulating a complete rv32i instruction set inside the wiring system of Terraria, we push back speeds to the early 70s era, tossing the ball firmly back into the court of silicon engineer without losing any software functionality."

So this is building a RISC-V *microcontroller* but what version of the ISA? 2.2 from 2017? Is it sucessfully passing conformance tests (https://github.com/riscv-software-src/riscv-tests)? I don't want to dunk on the project, but the title is over-selling and not scoping the context of the work. I look forward to some more updates from @misprit7!

Note: I'm the working group lead for distro-integration within the RISC-V Software Ecosystem (RISE) group.

It seems I have underestimated Terraria as a sandbox game.

Roger me sidewise, this is wonderfully crazy. I foresee a bright future for the creator.

Very impressive and in such a short time frame. So is the schema for this design only in the game? I assume if the game is saved it can be loaded on another computer? But can the schema/layout be emitted to a file so it can be parsed elsewhere?

Hmm I wonder if they ever fixed Terraria for Mac OS. I bought it based on hype but it wasn't handling my laptop display right so I never found out what it's about.

Cross-compile an emulator to RISC-V, then the false vacuum decays and cats and dogs live together.

Awesome to see something like this in Terraria instead of the usual minecraft!

The pitch is fantastically well written, for what it’s worth.

Next step: Self-hosted.

This is beyond impressive!!
