We normally do not even acknowledge or take them unless it crashes MAME. https://mametesters.org/rules.html > Reset and Pause bugs are not bugs unless they crash (Noted by Aaron) Reset and pause functionality are both not game player oriented. This is by design. Most PCBs don't have a reset button, and even if they do, the reset behavior is undefined. It is the equivalent of the watchdog firing on a PCB. Some games behave well when this happens; others not so well. The pause functionality in MAME is there for developers to be able to tweak with game parameters during a pause to affect the video. Thus, the video is going to be odd or messed up in a lot of cases. I have not seen any indication the board itself has a dedicated reset button. That isn't to say this might not be something that can be 'fixed' (At one time, the game appeared to reset without hanging). A board without reset-ability simply used power down/up (in the emulation case, needing to stop/start MAME or use SHIFT+F3 for a HARD RESET), which should do basically the same function of a power cycling.

No.19753 AJR Developer Feb 5, 2022, 02:32	I think the rule about not acknowledging reset bugs ought to be relaxed somewhat. Sure, soft-resetting certain systems when they least expect it can cause egregious glitches on actual hardware (Pokemon Yellow speedruns being a notorious example), but in most older arcade games soft reset glitches tend to be emulation bugs, and are often caused by mismanaging interrupt state or not resetting bank switches.
