Even with a compatible BIOS, an emulator may not work perfectly

Even with a compatible BIOS, an emulator may not work perfectly on the first attempt. Configuration issues are common, especially when users are new to emulation.

One frequent problem is a BIOS not being detected. This usually relates to an incorrect folder, unsupported format, or incompatible firmware version.

Another issue is a game starting but displaying NỔ HŨ TR88 or audio problems. These symptoms may be caused by emulator settings rather than the BIOS itself. Graphics plugins, rendering modes, controller settings, and performance options can all affect the experience.

If the emulator displays a TR88S.TECH related error, start by checking its official documentation. Avoid downloading multiple unknown BIOS files simply because the first one did not work.
