Use when scripting mGBA emulator automation in Lua - console API, ROM and save state operations, frame callbacks, input handling, memory reading for cheats and RAM watches, sockets, or TAS and speedrunner tooling.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

## Overview

- Save state management
- Callbacks for frame/events
- TCP socket networking

- Screenshot capture
### Opening Scripting Console
```
Tools → Scripting...
```
This opens a console where you can load and run Lua scripts.
## Top-Level Objects
### Available Objects
```lua
-- emu: CoreAdapter instance (available when game loaded)
-- C: Exported constants
-- callbacks: CallbackManager instance
-- console: Console instance
-- util: Basic utility library
-- socket: TCP socket library
```
### Console Output
```lua
console.log("Info message")
console.warn("Warning message")
console.error("Error message")
-- Create text buffer
buffer = console.createBuffer("My Buffer")
buffer:print("Text in buffer")
buffer:clear()
```
### Utility Functions
```lua
-- Expand bitmask to list
bits = util.expandBitmask(0xFF) -- {0,1,2,3,4,5,6,7}

How to install
mdr add codeatcode/oss-ai-skills/mgba@sha256:de0f5036d39fabc9The line at the top of this page pins the label v2.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
