I found an online NES emulator called Meowio that lets you replace every sound in a game (i.e., sound effects and music) with something else. I took advantage of this and played Super Mario Bros. 2 with every sound being the metal pipe sound. The site itself: https://www.information-superhighway.net/meowio/ (sorry no controller and mobile support. pc only)
