generate_site.py writes the Starlight project in website/ and nothing else: mkdocs.yml, the MkDocs hooks, theme overrides and stylesheet go, and the wiki is written in Starlight's syntax. Both workflows set up Node with the official actions/setup-node pinned by commit, run npm ci from the committed lockfile, build with the strict link validator and check the result with validate_site.py. The search weighs a page by what it answers: Start here pages first, a system page's cards and file names before a guide citing them, deep guides, launchers, aliases and frozen copies after. Status badges, hash blocks and the export change lists leave the index. The ranking sits at the centre of a range where the 13 queries of search_gate.py all answer, in the search box itself. 839 pages, every URL and 45,611 ids match the MkDocs build. The tests read the Starlight content and syntax.

# FAQ
|
|
|
|
## Do I need BIOS files?
|
|
|
|
For many consoles, yes: PlayStation 1 and 2, Saturn, Dreamcast, Neo Geo and
|
|
many home computers. For NES or Super Nintendo cartridges, usually not.
|
|
[What is a BIOS?](what-are-bios-files.md)
|
|
|
|
## How do I know which BIOS I need?
|
|
|
|
Run the installer with `--dry-run`. It lists what it would install and changes
|
|
nothing.
|
|
|
|
```sh
|
|
curl -fsSL https://raw.githubusercontent.com/Abdess/retrobios/main/install.sh | sh -s -- --dry-run
|
|
```
|
|
|
|
Your setup's page also lists every file, console by console.
|
|
|
|
## Is the command safe? { #is-piping-the-installer-into-a-shell-safe }
|
|
|
|
- It checks the installer's fingerprint before running it. If the download
|
|
does not match its expected fingerprint, it stops.
|
|
- It checks every file before saving it.
|
|
- It writes only in your BIOS folder.
|
|
|
|
To read the script before you run it:
|
|
|
|
```sh
|
|
curl -fsSL https://raw.githubusercontent.com/Abdess/retrobios/main/install.sh -o install.sh
|
|
less install.sh && sh install.sh
|
|
```
|
|
|
|
Details: [How the installer checks itself](installer.md#what-the-bootstrap-does).
|
|
|
|
## Will it change my other files?
|
|
|
|
No. It never touches games or saves, or a file it does not know. It replaces a
|
|
BIOS file with the wrong contents, and keeps yours.
|
|
|
|
## Windows or my antivirus blocks the command
|
|
|
|
Download the ZIP of your setup instead, from [Get your files](../which-pack.md).
|
|
It holds the same files.
|
|
|
|
## Can I run it again?
|
|
|
|
Yes. That is how you update. It downloads only what is missing or wrong.
|
|
|
|
## Can I undo it?
|
|
|
|
Yes. It keeps every file it replaces in a `retrobios-backup` folder, beside
|
|
your BIOS folder. The end of the run prints the line that puts them back: the
|
|
same command with `--restore` and that folder.
|
|
|
|
Details: [Files you already had](installer.md#files-you-already-had).
|
|
|
|
## Fill an SD card from a computer?
|
|
|
|
Yes. Name your setup and the BIOS folder on the card:
|
|
|
|
```sh
|
|
curl -fsSL https://raw.githubusercontent.com/Abdess/retrobios/main/install.sh \
|
|
| sh -s -- --platform retroarch --dest /path/to/sdcard/retroarch/cores/system
|
|
```
|
|
|
|
On Windows the line is different. Details: [Passing options](installer.md#passing-options).
|
|
|
|
## Does a BIOS work on every setup?
|
|
|
|
Yes. Only the folder changes, and sometimes the name.
|
|
|
|
## Why is a file missing from the ZIP?
|
|
|
|
Some files come with the emulator when you install it. The ZIP leaves those
|
|
out.
|
|
|
|
## Required or optional?
|
|
|
|
- **Required:** the emulator does not start games without it.
|
|
- **Optional:** games start, with small differences, like no start-up screen.
|
|
|
|
## My game shows a black screen
|
|
|
|
Most of the time, a BIOS file is missing or is the wrong version.
|
|
[When a game does not start](troubleshooting.md) shows how to check.
|
|
|
|
## Is this legal?
|
|
|
|
Laws on copying console firmware differ by country. The question is not
|
|
settled, and nothing here is legal advice. Details: [The project's legal position](legal.md).
|
|
|
|
To ask for a file to be removed, [open an issue](https://github.com/Abdess/retrobios/issues)
|
|
and name the file. A file is removed when the owner of its rights asks.
|
|
|
|
## Why keep recent consoles too?
|
|
|
|
Files disappear when stores close, like the 3DS and Wii U shops in 2023. We keep
|
|
them while they can still be found.
