A spiritual successor of the ultra-low latency version, Game Boy Interface High-Fidelity Edition (GBIHF) aims to provide the best source quality for further processing or archival. It is less than suitable for direct display connection, and you should be looking at the standard edition or speedrunning edition instead in such case.
