Summary	08106: plus4: Recently released Arkanoid +4 (FreeWare) Running way too fast
Description	When running the game, the game run at 2-3x the normal speed
Steps To Reproduce	mame plus4 -quik "/home/mame/Games/Roms/Commodore/plus4/arkanoid_+4.prg"
Additional Information	Was reported on Discord in #support. According to Tafoid this seems to be the problem: Regarding this issue (Arkanoid 2021 release), as near as I can tell, prior to this day (and very likely this commit), the presentation of the initial Arkanoid screen and music seemed to match current, but the in game music was very, very slow with the oddity of it slowly becoming quicker as the emulation continues. After this day (and likely this commit) and up to current, the initial Arkanoid screen music is slightly slower (might be a PAL/NTSC thing), but the in-game music/gameplay is super fast and I'd estimate 4x faster than it should. The date in question is February 12, 2013. https://github.com/mamedev/mame/commit/7e6fabfb9e6797461c3f8f037ab1d4e8a4c69c04
