Summary	09136: bayroute1: Unimplemented sound flag is due to missing sound ROMs
Description	Game: Bay Route (Unprotected US version) By a technicality, the MAME set containing the shortname "bayroute1" has the "Unimplemented sound" flag due to missing sound ROMs that are present in the non-merged FinalBurn Neo set. These files (according to FinalBurn Neo) are as follows: - sound.a7 - sound.a8 - sound.a9 - sound.a10 - sound.a11 I'm not sure about the dump quality of those files and their equivalent names to the sound ROMs in the parent set (bayroute), but once they are added to the set, the game now has working sound, although it may not be perfect.
Steps To Reproduce	1. Load the game from the original MAME non-merged set that does not contain the sound ROMs. 2. You may not hear any sound. 3. Replace the original set with the FinalBurn Neo non-merged set that does contain the sound ROMs, and load the game. 4. Sound is now present (especially the "Entering Bay Route" line at the title screen). However, during the game demo (for example), there may be a few imperfections with the sound compared to the parent set.
Additional Information	Severity remains at Minor due to the set's overall compatibility status of "Working". Let me know if you need to raise or lower it. If the original MAME non-merged set is loaded on FinalBurn Neo, it will give a warning message showing the missing files, as shown below.

As to if they are the correct roms for bayroute1, I cannot say. But the roms are not used anywhere in MAME currently. I'll mark this as confirmed, just to say that further investigation might be warranted.
No.23092 Robbbert Moderator 21 days ago	Made the sound roms visible to my MAME setup (without modifying MAME), and the sound works, together with a huge increase in speed. So I do think that this should be looked at.
No.23094 hap Developer 21 days ago	Sort of resolved here: https://github.com/mamedev/mame/commit/3fff2a61d557f41c8639cb09477a058ce161f16b These were dumped a long time ago but never added to MAME. A10 and A11 are bad dumps, so sounds are bad.
