# Release Candidate: Cooker Testing
If you are on SteamOS make sure you are in `Desktop Mode` before you begin.
**Do not use the the Rowan Skye Method**
We do not recommend to blindly install the Cooker without reading this guide and just hope for the best aka the `Rowan Skye Method`.
This is only recommended for chaotic blue draconic wolfkin testers living on the edge with nothing to lose.
## Step 1: Take some Backups
First take some backups:
- Make a copy of `~/.var/app/net.retrodeck.retrodeck/` folder and name it `old.net.retrodeck.retrodeck`
- Make a full back up or partial backups of the retrodeck folder normally under `~/retrodeck` or sdcard/other drive.
**On retrodeck folder backups:**
Generally, very few things would target the roms folder, but the other folders could be targeted for various scripts. Our recommendation would be to back up the full `~/retrodeck` folder, but as a tester you can decide how much you want to risk.
**Disclamer:**
The RetroDECK Team also had never had any major data loss so far and we do cooker updates almost daily.
## Step 2: Download the Cooker
- Download the latest cooker release from: [RetroDECK Cooker: Latest](https://github.com/XargonWan/RetroDECK-cooker/releases/latest) to your download folder.
- Make a note of the , is a randomly generated word written like cooker-0.8.0b-, in this example it's `HelloWorld`.
## Step 3: Terminal
Open the terminal window.
### Remove and Install
- `flatpak remove net.retrodeck.retrodeck` and press (y) yes to remove RetroDECK. If you have more then one version installed for some reason choose to remove all versions.
- `flatpak install --user --bundle --noninteractive -y "~/Downloads/RetroDECK-cooker.flatpak"` this will install RetroDECK Cooker.
## Step 4: Upgrade
**IMPORTANT:**
Under **NO** circumstances press the `Full Wipe and Fresh Install` button. That is **NOT** to be confused with Configurators `Reset RetroDECK` option. This in fact a `Nuke Everything` option, it will remove all of RetroDECK including all ROMS/BIOS/Downloaded Media and everything else you have in RetroDECK's folders...forever.
### Upgrading:
- After the installation is complete type: `flatpak run --command=sh net.retrodeck.retrodeck` followed by `retrodeck`.
- Press the `Upgrade` button and keep the installation moving until all the steps are complete and RetroDECK will launch.
- Quit RetroDECK again and save all the output from the terminal into a text file.

## 0.8.0b upgrade & testing
**IMPORTANT:**
Check for the message `"In version 0.8.0b, the following changes were made that required config file updates/reset or other changes to the filesystem:"` in the terminal. This is a sign that tell you the post update migration is running, this is crucial for RetroDECK's upgrade to fully happen.
This is what should happend in the post migration.
```
- Remove any of the following files, if they exist:
"$HOME/.steam/steam/controller_base/templates/RetroDECK_controller_config.vdf"
"$HOME/.steam/steam/controller_base/templates/RetroDECK_controller_generic_standard.vdf"
"$HOME/.steam/steam/controller_base/templates/RetroDECK_controller_ps3_dualshock3.vdf"
"$HOME/.steam/steam/controller_base/templates/RetroDECK_controller_ps4_dualshock4.vdf"
"$HOME/.steam/steam/controller_base/templates/RetroDECK_controller_ps5_dualsense.vdf"
"$HOME/.steam/steam/controller_base/templates/RetroDECK_controller_steam_controller_gordon.vdf"
"$HOME/.steam/steam/controller_base/templates/RetroDECK_controller_neptune.vdf"
"$HOME/.steam/steam/controller_base/templates/RetroDECK_controller_switch_pro.vdf"
"$HOME/.steam/steam/controller_base/templates/RetroDECK_controller_xbox360.vdf"
"$HOME/.steam/steam/controller_base/templates/RetroDECK_controller_xboxone.vdf"
- The line "[nintendo_button_layout]" should be renamed "[abxy_button_swap]" in retrodeck.cfg
- The folder "/var/config/emulationstation" should be renamed to "/var/config/ES-DE" (internal Flatpak paths)
- ES-DE should be put through a reset process (verify via logs)
- MAME should be put through a reset process (verify via logs)
- Vita3K should be put through a reset process (verify via logs)
- GZDOOM should be put through a reset process (verify via logs)
- If the folder ~/retrodeck/.logs exists, it should be renamed to ~/retrodeck/logs
- The RPCS3 saves should be migrated by the following steps:
- The folder ~/retrodeck/backups should be created if it doesn't already exist
- A backup of current RPCS3 save data should be created at ~/retrodeck/backups/(date and time backup started)_rpcs3_save_data.zip
- The symlink and real folders for save data should be switched:
- The folder at ~/retrodeck/saves/ps3/rpcs3 should now be real
- The folder at ~/retrodeck/bios/rpcs3/dev_hdd0/home/00000001/savedata should now be a symlink back to ~/retrodeck/saves/ps3/rpcs3
- Rename the folder ~/retrodeck/bios/switch/registered to ~/retrodeck/bios/switch/firmware
- Default ROMs folders should be recreated by ES-DE to add new systems
```
