# User Handbook - Third party tools and extras
The Eden emulator by itself lacks some functionality - or otherwise requires external files (such as packaging) to operate correctly in a given OS. Addendum to that some repositories provide nightly or specialised builds of the emulator.
While most of the links mentioned in this guide are relatively "safe"; we urge users to use their due diligence and appropriatedly verify the integrity of all files downloaded and ensure they're not compromised.

## Mirrors
The main origin repository is always at https://git.eden-emu.dev/eden-emu/eden.
- https://github.com/eden-emulator/mirror
- https://git.crueter.xyz/mirror/eden
- https://collective.taymaerz.de/eden/eden
Other mirrors obviously exist on the internet, but we can't guarantee their reliability and/or availability.
If you're someone wanting to make a mirror, simply setup forgejo and automatically mirror from the origin repository. Or you could mirror a mirror to save us bandwidth... your choice!
## Configuring Obtainium
Very nice handy app, here's a quick rundown how to configure:
1. Copy the URL: https://git.eden-emu.dev/eden-emu/eden/ (or one of your favourite mirrors)
2. Open Obtainium and tap Add App.
3. Paste the URL into the "App Source URL" field.
4. Override Source: Look for the "Override Source" dropdown menu and select Forgejo (Codeberg). • Note: Even though the site isn't Codeberg, it uses the same Forgejo/Gitea backend, and this setting tells Obtainium how to read the release data.
5. Click Add: Obtainium should now be able to parse the releases and find the APK files.
## Configuring ES-DE
### Method 1
1. Download ZIP from [here](https://github.com/GlazedBelmont/es-de-android-custom-systems)
2. Unzip the file and extract `es_systems.xml` and `es_find_rules.xml` to `\Odin2\Internal shared storage\ES-DE\custom_systems`.
3. Press `Start -> Other Settings -> Alternative Emulators` and set it to Eden (Standalone).
### Method 2
1. Navigate to `\Odin2\Internal shared storage\ES-DE\custom_systems`.
2. Add this to your `es_find_rules.xml`:
```xml
dev.eden.eden_emulator/org.yuzu.yuzu_emu.activities.EmulationActivity
com.miHoYo.Yuanshen/org.yuzu.yuzu_emu.activities.EmulationActivity
```
3. Add this line of text to your `es_systems.xml` underneath where the rest of your switch system entries are:
```xml
%EMULATOR_EDEN% %ACTION%=android.nfc.action.TECH_DISCOVERED %DATA%=%ROMPROVIDER%
```
