TIC-80 — Fantasy Computer for Making and Sharing Tiny Games

Introduction

TIC-80 is a free, open-source fantasy computer for making, playing, and sharing tiny games. Inspired by retro 8-bit consoles, it provides a constrained creative environment with a 240x136 pixel display, 16 colors, 256 sprites, and a built-in code editor. It supports Lua, JavaScript, MoonScript, Wren, Fennel, Squirrel, and Ruby.

What TIC-80 Does

• Provides an all-in-one game creation environment in a single executable
• Includes built-in editors for code, sprites, maps, sound effects, and music
• Runs games in a constrained retro-style virtual machine (240x136, 16 colors)
• Exports games as standalone HTML5, desktop executables, or cartridge files
• Supports multiple scripting languages (Lua, JS, Wren, Fennel, and more)

Architecture Overview

TIC-80 emulates a fantasy computer with fixed hardware specs: a 240x136 display, 16-color palette, 256 8x8 sprites, 4-channel sound, and a map editor. The runtime interprets scripts through embedded language runtimes (Lua via LuaJIT, JavaScript via QuickJS, etc.). Games are distributed as .tic cartridge files that bundle code, art, and audio.

Self-Hosting & Configuration

• Download prebuilt binaries for Windows, macOS, Linux, Android, or Raspberry Pi
• Build from source using CMake with SDL2 dependency
• The Pro version unlocks bank switching for larger games (available as donation)
• Cartridges can be shared on the TIC-80 website community hub
• CLI mode available for headless builds and automation

Key Features

• Complete game development suite in a single 2MB application
• Built-in sprite, tilemap, SFX, and music tracker editors
• Deliberately constrained specs that encourage creative problem-solving
• Multi-language support including Lua, JavaScript, Wren, and Fennel
• Active community gallery for sharing and discovering games

Comparison with Similar Tools

• PICO-8 — Similar concept but proprietary; TIC-80 is free and open source
• Godot — Full game engine with no constraints; TIC-80 embraces creative limitations
• Scratch — Visual block programming for kids; TIC-80 uses text-based scripting
• Love2D — Lua game framework without constraints; TIC-80 adds retro specs and built-in editors
