The tools page lists the load and fallback lines each core's BIOS is read from, and core_probe rejudge. The method page says a game can work on the emulator's own BIOS.

How emulators are tested
Some pages say what an emulator does with a file. Where we ran it to check, the emulator's page shows a Tested block. Every result is on the Measurements page.
What a test does
- A script runs the emulator with no window and no sound.
- It starts a game and runs it for a set time, at least twice.
- It compares the screens with ones we checked by eye.
Your BIOS folder
We also test the files as you install them, for RetroArch, Batocera and RetroBat, then start a game. The setup's page shows the result under Tested.
What a result says
| Result | Meaning |
|---|---|
| works | the game reached a screen it shows when it works |
| works on its built-in BIOS | it worked, but the emulator refused the file and ran its own BIOS |
| BIOS error | the emulator said a BIOS is missing or wrong |
| crash | the emulator stopped |
| hang | the screen stayed blank, or the run never ended |
| unknown | none of these could be shown |
| no verdict | an older test that only compared screens |
| ms per frame | a speed test |
How a file is proven
The game runs with no BIOS and with the BIOS alone. Then it runs with a wrong file under the BIOS name: zeros, half the file, or another region's BIOS.
- Required: no BIOS fails, the BIOS alone works.
- Built-in stand-in: no BIOS still works.
- Checked: a wrong file is refused.
When tests run
A maintainer starts a test run. A clear result updates the emulator's page. Anything else waits on the Measurements page for someone to read the code.
What a result keeps
Each result names its method, the computer it ran on and the exact build of the emulator. Its inputs are kept by fingerprint. A result holds for that build and those inputs only.
A speed figure depends on the computer and how busy it was. It is never shown without them.
Where results are kept
Each result is a full record in the
measurements/
folder of this project. A record is never changed once added. A new run is
added beside it, and a correction names the record it replaces.
The results so far ran on these computers:
