## What it is
Computerraria is a fully compliant RISC-V (rv32i) computer built entirely inside the wiring system of the game Terraria, paired with a Rust toolchain and a wiring accelerator mod. It runs real programs like Pong on an in-game CPU with ~5kHz clock speed and 96KB of RAM.

## Use cases
- build a working RISC-V CPU inside Terraria
- run programs on an in-game computer in Terraria
- learn how CPUs and logic gates work
- emulate rv32i instructions with game wiring
- explore redstone-style computing in Terraria
- run Pong on a CPU made of logic gates

## When to choose
- you want a fully compliant rv32i computer implemented in Terraria's wiring system
- you're interested in educational CPU/logic-gate projects in games
- you want to write and run Rust programs on an in-game CPU

## When to avoid
- you need a practical or fast RISC-V emulator for real workloads
- you don't play Terraria or use its modding ecosystem
- you need Windows support without workarounds, since only Linux is fully supported

## Facets
- artifact type: application
- maturity: active
- function: simulation, interpreter, developer-tools
- domain: simulation, gaming-tools, hardware, programming-languages
- platform: windows, game-engine, rust
- tags: risc-v, terraria, logic-gates, cpu-emulation, terraria-mod, rv32i, wiring, linux
