If your favorite game isn't working on Xenia, the best way to prioritize it would be to find it in the game compatibility list and give the OP a thumbs up reaction. This allows the developers to find popular games quickly.
If you've looked in the list and you couldn't find your game - see the following section:
If you would like to submit a game-compatibility issue, please use the following format until a proper solution is available:
Title: {UNIQUE GAME ID} - {GAME NAME}
Content to include:
- Marketplace link
- A reference to the version of xenia tested on
- A short description of how the game runs or any issues
- A log file (run xenia with "xenia default.xex --log_file=output.log" and either attach a compressed output.log to the issue, or upload output.log to gist.github.com)
- If you can: Checklist or standard list of issues
- If you don't have the ability to add labels to your issue, please comment which labels should be added. (gotta love the github contributor system)
