The Start here pages ran 460 to 2,100 words and the first command of Get your files sat 254 words down. Each page now opens on its action, with short sentences and one fact per block. The facts a newcomer does not act on moved one level down: the legal analysis to wiki/legal.md, the project terms to wiki/reference-terms.md, the annotated run and the installer failures to the installer page, collection figures to a new Explore index. tests/test_site_copy.py holds the budgets on the generated pages, and the testing guide states them with their reasons. Four statements the repository contradicts are rewritten: prboom.wad is compiled into PrBoom (emulators/prboom.yml), Batocera reports a mismatch as UNTESTED (batocera-systems checkBios), 13 hle_fallback entries are required, and the gaps headline splits missing firmware from game data and unread entries.

When a game does not start
Most of the time, a BIOS file is missing or is the wrong version. Three checks find it.
1. Check your BIOS folder
Run the command with --check. It changes nothing.
curl -fsSL https://raw.githubusercontent.com/Abdess/retrobios/main/install.sh | sh -s -- --check
Read the count line:
1/109 present (0 verified, 1 wrong hash)
wrong hash: a file is there, but its contents are wrong. It may be for another region or model, or damaged.- Fewer present than the total: some files are missing.
0 wrong hashand all present: your files are fine. Go to step 3.
2. Fix the files
Run the same command without --check. It adds the missing files and replaces
the wrong ones. It keeps the old ones in retrobios-backup, beside your BIOS
folder.
3. Check the folder and the names
- Right folder? Your emulator must read the folder the command used. Your setup's page names it.
- Is the name exact?
scph5501.binandSCPH-5501.BINare two different names. On Linux, capital letters count too. - Unzipped by hand on Linux? Use the command. Some emulators there need a lower-case name the ZIP lacks.
- A ZIP in parts will not open? Download every part, like
Pack.part1of2.zipandPack.part2of2.zip. Unzip each one into the same folder.
One console only
Add --system and its name:
curl -fsSL https://raw.githubusercontent.com/Abdess/retrobios/main/install.sh | sh -s -- --check --system sony-playstation --verbose
--verbose names each missing or wrong file. --list-systems shows every
console name.
My setup says UNTESTED
Batocera shows UNTESTED for a file whose contents it does not expect. Run
the command without --check to replace it.
If the command fails
- Network error: check that github.com opens, then try again.
- Permission denied: on Batocera, Recalbox and ROCKNIX, put
sudoand a space before the command. It then runs as the administrator. - No setup found: name it yourself, with your BIOS folder:
curl -fsSL https://raw.githubusercontent.com/Abdess/retrobios/main/install.sh | sh -s -- --platform retroarch --dest ~/.config/retroarch/system
