Version 0.3.0 - 2026-08-01

Local leaderboard displayed on the backglass of AtGames devices. The leaderboard data is read from a JSON file stored on the local USB drive.
External Applications can opt in to firmware-managed stdout and stderr logs with <logging>true</logging> in their metadata XML
The firmware provides ATGAMES_LOG_PATH with the absolute path of the active log file when logging is enabled
These integrations are available on Legends 4KP firmware 6.1.30, 6.0.34B, and 6.1.30D, and HDP firmware 1.0.30

Version 0.2.0 - 2026-07-29

This release improves compatibility across the AtGames Legends device family and makes the SDK easier to use:

Improved display support across different AtGames devices
Improved control support across different AtGames devices
Added sdk/displays/ helpers for display topology and GPU-accelerated Backglass, DMD, and Marquee output
Added the arcade-test-app diagnostic application for controls, displays, HTTPS, and device permissions
Streamlined documentation for a simpler, clearer development experience

A new Software Development Kit is available for download on atgames.net. This release includes:

Docker-based cross-compilation support for AtGames External Applications
Automatic USB packaging output under dist/external/<app-id>/
Two SDL2 sample applications:
- brick-breaker-app: a portrait Brick Breaker sample game
- skyfall-app: a vertical falling game with steering, obstacles, and scoring
Shared controls helper for SDL GameController, keyboard input, and CE-mapped cabinet controls
Environment helper (sdk/AtGamesHelpers.h) for reading firmware-provided values:
- ATGAMES_USERNAME
- ATGAMES_UNIQUE_ID
- ATGAMES_DEVICE_TYPE_ID
- ATGAMES_DEVICE_TYPE_NAME
- ATGAMES_FIRMWARE_VERSION
Shared local leaderboard helper with score persistence and ranking utilities
Shared leaderboard overlay for rendering in-game high-score screens
Shared HTTP request helper for firmware-backed HTTPS requests
New developer documentation
