***By default Xenia runs ALL XBLA/digital games in demo/trial mode.***
To run games in full/activated mode you will have to compile Xenia with [mask_ptr =](https://github.com/xenia-project/xenia/blob/master/src/xenia/kernel/xam/xam_content.cc#L52) 0xFFFFFFFF instead of 0.
Check the [compatibility list](https://github.com/xenia-project/game-compatibility/issues). If it's not there, ask in the [Discord #help channel](https://discord.me/xenia-emulator) or test it yourself.
To play games in 4:3 you need to build Xenia with `video_mode->is_widescreen = 0` instead of 1 [here](https://github.com/xenia-project/xenia/blob/master/src/xenia/kernel/xboxkrnl/xboxkrnl_video.cc#L138).
Refer to the [Game hacks, mods, etc. page](../wiki/Game-hacks,-mods,-etc).
# Troubleshooting
Make sure:
* You're not using outdated or invalid [launch parameters](#Options).
* You downloaded a *Release* build, not a *Checked* one.
Saves are broken in a majority of games, especially ones with user profile saves.
As for saves, etc that worked previously in older builds of Xenia, create a text file in the same directory as xenia.exe named `portable.txt`.
Saves are in `Documents\xenia\content` by default.
If you're having problems with the Halo games make sure that you're using a [D3D12](https://ci.appveyor.com/api/projects/benvanik/xenia/artifacts/xenia-d3d12.zip?branch=d3d12&job=Configuration%3A%20Release&pr=false) build and your GPU supports it.
*Halo: Combat Evolved Anniversary does not work.*
**Xenia is a *work in progress* so expect issues.**
