RayStorm (Arcade)

In the far future, under strict martial law, a rebellion grew so strong that it wants to destroy Earth, and the player's goal is to prevent it from happening by blasting down everything.

In-Game Debug Functions#

This needs some investigation. Discuss ideas and findings on the talk page. Specifically: The code provider noted the code is a WIP but they doesn't seem to have updated it since; maybe verify if there's a workaround to access the other menus?

By using the following MAME cheat, a debug menu can be entered by pressing 1P C. However, many of its functions don't seem to work; aside from CANCEL, which exits the menu, only CLUT EDITER, TIM CHECKER and RESET (which appropriately resets the game) do.
