An install writes retrobios-backup/<folder>.install.json beside the BIOS folder: each file it placed with its sha1, size and source, and the choice it made. The next run for the same setup and folder takes that choice when the command line chose nothing, in line mode and on the full screen, and says so. A record that cannot be read is said once and ignored. A record event reports it. With one setup found, the full screen opens on its plan, Change where one row away. The plan's Install row says the size its headline says.

First install, step by step
From an empty BIOS folder to a checked one.
Needed: internet and some free space.
1. Open a terminal and paste
A terminal is a window for typing commands. Paste the matching line, then press Enter.
Open the Start menu. Type PowerShell and open it.
irm https://abdess.github.io/retrobios/i.ps1 | iex
Open Terminal, in Applications, then Utilities.
curl -fsSL https://abdess.github.io/retrobios/i | sh
Open a terminal.
curl -fsSL https://abdess.github.io/retrobios/i | sh
Switch to Desktop Mode and open Konsole.
curl -fsSL https://abdess.github.io/retrobios/i | sh
Install Termux, a terminal app, and run this line. It installs Python and asks Android for storage access: allow both.
curl -fsSL https://abdess.github.io/retrobios/i | sh
On Batocera, Recalbox and similar setups, see Get the files.
2. Check the setup it found
With one setup found, it opens on step 3, its folder on the second line. With none or several, it asks:
RetroBIOS: Where to install?
Found on this machine:
> <your setup>
Another setup or folder
BIOS folder: <its folder>
- Right folder? Press Enter.
- Wrong folder, or a handheld's SD card? Choose Another setup or folder (Change where from step 3). Press / and type the device (Miyoo Mini), or browse.
Arrows move, Enter chooses, Esc goes back (A and B on a handheld). On a touch screen, tap a row twice to open it, once to tick a box.
3. Install
Press Enter on Install. Choose systems picks the consoles to keep. Run it again later: it keeps that choice, one press.
Game data (only a game reads it) has its own row.
Old card? In a card reader, choose Copy the BIOS files from an old card or a folder, then the card.
4. Wait
Esc or Ctrl+C stops, B on a handheld. Run again to resume.
5. Read the result
- Done: every file on the list is in place.
- Finished with errors: run it again. It retries only those.
- Finished with files missing: run it again online.
- Nothing installed: the screen says why. See If it stops.
Screen readers: add --plain.
What the command does
Check it later
Add --check to the same command. It changes nothing.
curl -fsSL https://abdess.github.io/retrobios/i | sh -s -- --check
Result:
Every file on the list is in place.
Missing required files are named below it.
Undo
Replaced files go to retrobios-backup, and --restore puts them back.
If it stops
Nothing was found here.
Choose the setup, then its folder. Where the screen offers Another setup or folder, choose it first.
Error: Python 3.8 or newer is required.
Run the command the message shows, then the installer again.
RetroPie 4.8 has Python 3.7.3, and its update finds nothing newer. Run it on
a computer, with RetroPie's bios share open, \\RETROPIE\bios from Windows:
curl -fsSL https://abdess.github.io/retrobios/i | sh -s -- --platform retropie --dest <the bios share>
Error: the downloaded installer does not match its expected fingerprint.
Nothing ran, because something changed the file. Try another network.
Cannot create ...
That folder cannot be written. Do what the message says.
The card is full
Nothing was written. Free some space there.
The game still does not start
