Perhaps you can explain where you see this speed issue and how others would be able to observe this? I'd also try running with a fresh configuration for that game and see if that fixes it. (delete/remove game or driver .cfg/.ini)
No.20357 sasuke Tester Jul 4, 2022, 15:17	As I mentioned in my comment above, this only occurred with Arcade64, the unofficial build. Since it did not occur in official binary, you may close the ticket. I’m sorry. Arcade64 is here. https://arcade.mameworld.info/ In addition: It occurs even after deleting cfg and ini, and the cause is unknown. To play at its true speed, the maincpu must be overclocked by 200%. I am attaching a video to show what I am talking about.

As I understand, there is a forum which you can talk arcade64 - I'd suggest you bring it up over there. https://www.1emulation.com/forums/forum/127-arcade/ Closing
No.20514 Robbbert Senior Tester Sep 8, 2022, 16:38	Probably a good idea to let me know about these... only just found this report. A check of megasys1.cpp revealed a hack by the previous maintainer. I don't know what purpose it served, but it's been removed now and phantasm runs at the same speed as in MAME.
