# First install, step by step
|
|
|
|
From an empty BIOS folder to games that start.
|
|
|
|
**You need:** internet and some free space. The installer says how much.
|
|
|
|
## 1. Open a terminal and paste
|
|
|
|
A **terminal** is a window where you type commands. Paste the line for your
|
|
system, then press Enter.
|
|
|
|
<Tabs syncKey="os">
|
|
<TabItem label="Windows">
|
|
|
|
Open the Start menu. Type **PowerShell** and open it.
|
|
|
|
```powershell title="PowerShell"
|
|

|
|
```
|
|
|
|
</TabItem>
|
|
<TabItem label="macOS">
|
|
|
|
Open **Terminal**. It is in Applications, then Utilities.
|
|
|
|
```sh title="Terminal"
|
|
curl -fsSL https://raw.githubusercontent.com/Abdess/retrobios/main/install.sh | sh
|
|
```

|
```sh title="Terminal"
|
|
curl -fsSL https://raw.githubusercontent.com/Abdess/retrobios/main/install.sh | sh
|
|
```
|

|
|
```
|
|
|
|
</TabItem>
|
|
<TabItem label="Android (Termux)">
|
|
|
|
Install **Termux**, a terminal app. Run these three lines in it.
|
|
|
|
```sh title="Terminal"
|
|
pkg install python
|
|
termux-setup-storage
|
|
curl -fsSL https://raw.githubusercontent.com/Abdess/retrobios/main/install.sh | sh
|
|
```
|
|
|
|
</TabItem>
|
|
</Tabs>
|
|
|
|
On Batocera, Recalbox and similar setups, see
|
|
[Get your files](../which-pack.md).
|
|
|
|
## 2. Check the setup it found
|
|
|
|
It opens a menu:
|
|
|
|
```
|
|
RetroBIOS: Where do you play?
|
|
Found on this machine:
|
|
> <your setup>
|
|
Another setup or folder
|
|
BIOS folder: <its folder>
|
|
```
|
|
|
|
- **Right folder?** Press Enter.
|
|
- **Wrong folder?** Choose **Another setup or folder**, then browse to yours.
|
|
- **A handheld's SD card in a reader?** It is listed, as **muOS SD card**.
|
|
|
|
Arrows move, Enter chooses, Esc goes back. A handheld's A and B do the same.
|
|
|
|
## 3. Install
|
|
|
|
The next screen counts missing files and free space.
|
|
Press Enter on **Install**. **Choose systems** keeps the consoles you
|
|
play.
|
|
|
|
**Old card?** In a card reader, choose **Copy the BIOS files from your old
|
|
card or a folder**, then the card. It stays unchanged.
|
|
|
|
## 4. Wait
|
|
|
|
Esc or Ctrl+C stops, B on a handheld. Run again to resume.
|
|
|
|
## 5. Read the result
|
|
|
|
- **Done**: all files are in place.
|
|
- **Finished with errors**: run the command again. It retries only those.
|
|
- **Nothing installed**: the screen says why. See [If it stops](#if-it-stops).
|
|
|
|
For questions line by line (screen readers), add `--plain`.
|
|
|
|
## What the command does
|
|
|
|
<!-- image: install-flow -->
|
|
|
|
## Check it later
|
|
|
|
Add `--check` to the same command. It changes nothing.
|
|
|
|
<!-- os-tabs -->
|
|
```sh
|
|
curl -fsSL https://raw.githubusercontent.com/Abdess/retrobios/main/install.sh | sh -s -- --check
|
|
```
|
|
|
|
All good:
|
|
|
|
```
|
|
109/109 present (109 verified, 0 wrong hash)
|
|
```
|
|
|
|
## Undo
|
|
|
|
Files it replaces go to a `retrobios-backup` folder beside your BIOS folder.
|
|
The result says how to restore them.
|
|
|
|
## If it stops
|
|
|
|
### Nothing was found here.
|
|
|
|
Choose **Another setup or folder**, then your setup and its folder.
|
|
|
|
### Error: Python 3.8 or newer is required.
|
|
|
|
The message shows the command that installs Python. Run it, then run the
|
|
installer again.
|
|
|
|
A RetroPie 4.8 image has Python 3.7.3, and its update command finds nothing
|
|
newer. Run it on a computer, the `bios` share open:
|
|
|
|
<!-- os-tabs windows: --platform retropie --dest \\RETROPIE\bios\ -->
|
|
```sh
|
|
curl -fsSL https://raw.githubusercontent.com/Abdess/retrobios/main/install.sh | sh -s -- --platform retropie --dest <the bios share>
|
|
```
|
|
|
|
### Error: the downloaded installer does not match its expected fingerprint.
|
|
|
|
The download was cut short. Nothing was changed. Run the command again.
|
|
|
|
### Cannot create ...
|
|
|
|
You cannot write there. Do what the message says.
|
|
|
|
### The card is full
|
|
|
|
Nothing was written. Free some space, or choose another folder.
|
|
|
|
### The game still does not start
|
|
|
|
