Learning path · 20 tutorials

Prepare your own games and platform files, then check touch or physical controls, saves, offline play, display layouts and launch issues.

[Start with the first tutorial](<https://allluckly.cn/en/guides/yearn-getting-started/>)[About Yearn](<https://allluckly.cn/en/apps/yearn/>)

Yearn does not include game ROMs. With your own files ready, take one game through import, launch, saving and loading again before organising a larger collection.

A successful import does not guarantee every game is compatible. A save entry, a cloud-sync indicator and successfully restored progress are separate checks. Keep original files and existing progress when investigating a difference.

## Import & game library

Prepare games you are entitled to use and check formats, companion files and the library.
