In Romcenter, games that require dl-1425.bin (such as 1944, sfa, ddsom, etc.) often show up as incomplete (yellow status) even when the correct qsound_hle.zip file is present in the right location. This is because Romcenter does not treat this file as a standard BIOS file, and the BIOS merge settings do not apply. Users encountering this behavior should rest assured that their games will still run correctly in MAME despite the warning.
