Cannot confirm. Can anyone else confirm or forcibly duplicate?

No.22213 Tafoid Administrator Jul 5, 2024, 17:40	It was changed here, between 0.216 and 0.217, when all clocks were fixed to be based on actual OSC shown on the board or confirmed otherwise. https://github.com/mamedev/mame/commit/86de06e00949376cc24e340274ee40103bad0851 Is there proof that the earlier speed is correct? I've done a cursory check for a non-MAME related recording on youtube with nothing showing. At this point I'm pretty sure current behavior is "as on PCB".

I supplied the rom dump for this game from a working pcb to Reip many years ago and when it was emulated I let him know that the everything looked good but that the music was playing to fast. Even the speech samples were fast. I sold the pcb shortly after it was emulated so I cannot provide any frequency checks.
