* The BIOS & Firmware files go into the `~/retrodeck/bios/` directory <br>
**Example:**<br>
You have a BIOS for the PSX called `exampleBIOSPSX.bin`, you just put that file into the `~/retrodeck/bios/` folder.
## Step 3: ROMs
**NOTE:** On the Steam Deck this step needs to be done in Desktop Mode
### On ROMs
Rom files needs to be put in their corresponding system directory inside the `roms` folder.<br>
Note that the `roms` folder location can be different depending on where you choose to put it during the installation process. The following options are available during the installation:
#### **Choice: Internal**<br>
If during the installation of RetroDECK you choose the Internal option for the roms folder:<br>
The roms folder is:`~/retrodeck/roms/`
#### **Choice: SDCard**<br>
If during the installation of RetroDECK you choose the SDCard option for the roms folder:<br>
The roms folder is: `<sdcard>/retrodeck/roms/`<br>
(Please note that the `<sdcard>` is an example and not called so inside your Linux/SteamOS system but rather your unique per SDCard ID number).<br>
#### **Choice: Custom**<br>
If during the installation of RetroDECK you choose the Custom option for the roms folder:<br>
The roms folder where ever you choose.
### Let's get started on ROMs:
Read up on [ES-DE Folders and Files](../wiki_emulationStation_de/esde-folders-files.md) to see what folder each system has or read the readme file in each systems folder under `~/retrodeck/roms/`
* Put the corresponding roms inside the corresponding system folder
**Example:**<br>
You have an example NES game called `ExampleNESGame.nes`<br>
You have to put that game into the `/retrodeck/roms/nes` folder.
## Step 4: Playing the Games
### Steam Deck - Gamemode
Return to gamemode on the Steam Deck and start up RetroDECK. Now the systems you put rom files for should be shown and be able to be played.
**Example:**<br>
The NES column should now be shown with our `ExampleNESGame.nes` from `Step 3`
### Linux Desktop
Start up RetroDECK from Steam. Now the systems you put rom files for should be shown and be able to be played.
**Example:**<br>
The NES column should now be shown with our `ExampleNESGame.nes` from `Step 3`
## Step 5: Making the games "pretty" with videos, images and art.
Do the following:
1. Make an account on [Screenscraper](https://www.screenscraper.fr/)
2. Read up on scraping and the various settings that exist for it in the [ES-DE User Guide](../wiki_emulationStation_de/esde-guide.md)
3. Login to your screenscraper account inside RetroDECK.
4. Setup the scraping how you want it.
5. Start scraping.
6. Look at your nice pretty games.
