No—RetroPie does not require BIOS files for every game. Whether you need one depends on the system being emulated and the emulator RetroPie uses for it. Check that system’s current RetroPie documentation and, if needed, the emulator’s own instructions before adding a file.
Do I need a BIOS for every RetroPie game?
No. BIOS requirements are specific to an emulated system and emulator or core, not a single RetroPie-wide setting. Some setups may need a system ROM; others may not. A BIOS for one system does not automatically serve another, and the same console may have different requirements depending on the selected emulator.
For the combination you use, start with the relevant page in RetroPie’s BIOS documentation and the system’s own page, such as its PlayStation 1 documentation. Confirm whether the file is required or optional and follow the current filename and destination instructions. The documentation pages are the authoritative place to verify current details; historical forum examples should not be treated as universal setup instructions.
How do I find the right BIOS requirement?
- Identify the system. Determine which console or computer the game targets.
- Identify the emulator or core RetroPie launches. Requirements can differ between emulators for the same system. If you are unsure, check the launch configuration or runcommand information for that game.
- Check the system’s current RetroPie documentation. Look for whether a BIOS is required or optional, and note the exact filename, capitalization, and destination.
- Check the emulator’s documentation if anything remains unclear. Use it to resolve emulator-specific path or filename requirements rather than relying on a generic folder rule.
Do not infer that a BIOS is needed just because a game fails to start. The failure may have another cause, and a missing system ROM is only one possibility.

Where do I put a BIOS file?
Many RetroPie configurations use a BIOS directory, commonly shown as /home/pi/RetroPie/BIOS in community setup discussions. That is a starting point, not a guarantee that every emulator expects every file directly in that directory. Some configurations use system-specific subdirectories or other emulator-specific locations. For example, a historical Amiga support discussion refers to a separate Amiga directory for Kickstart ROM files; current instructions should come from the BIOS documentation and the documentation for the emulator in use.
Keep BIOS files distinct from game ROMs. Older discussions of USB setups distinguish BIOS storage from ROM storage, but the actual paths and USB behavior can vary by RetroPie version and configuration. Confirm the current destination before copying files, especially when using USB migration.

What do system-specific examples show?
- PlayStation 1: A RetroPie forum thread about BIOS filename confusion points readers toward PlayStation-specific guidance. It illustrates why the system’s own instructions matter; it is not a current, complete filename or compatibility list. See the forum discussion and verify details in the current PS1 documentation.
- Amiga: Historical Amiberry troubleshooting discusses Kickstart ROMs and an Amiga BIOS subdirectory. Treat this as an example of emulator-specific placement, not a universal path. See the Amiberry discussion.
- TI-99: A support thread about ti99sim describes a system ROM lookup problem where folder placement mattered. That illustrates path exceptions; it does not establish a folder rule for other systems. See the ti99sim thread.
What should I check if a game still will not launch?
If the documentation says a BIOS is required and the emulator cannot find it, check the system ROM before changing the game image. Verify the selected emulator, the exact filename and letter case, and the complete destination path. A file with the right contents but the wrong name or location may not be detected.
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Repair Windows errors before they cause bigger problems3Fix the driver behind crashes, sound loss and screen glitchesThen inspect the emulator or runcommand log for a missing-file or path message. The exact logging workflow varies, so use the instructions for the emulator and RetroPie version you have rather than assuming there is one universal log procedure. If the BIOS appears correctly placed, investigate other causes of the launch failure instead of adding unrelated BIOS files.

Can I download or copy BIOS files from anywhere?
Do not use unauthorized BIOS or game-ROM download sites. BIOS files are copyrighted firmware, and the legality of making or using a personal backup depends on applicable law and rights-holder permissions. The available guidance does not establish a copying method that is lawful everywhere, so check the rules that apply where you live and use only files you are authorized to possess.
RetroPie community discussions also direct users away from requests to share ROMs. See the community discussion about acquiring content for that community context.
