Unfortunately, I was unable to test on either mupen64 using jabo or mupen64plus. Using jabo in mupen64 resulted in nothing but a black screen (with perfectly functioning audio), and I have no idea how to set up mupen64plus. I didn't know how to set the controls or other options, and as such, I didn't make it past the title. I tested with the other video plugins on N64Hawk, and found that both glide64 and glide64mk2 work (neither of the glitches happen). Rice doesn't, but the glitch is different; instead of showing your last pause, it just renders the game normally, as if there were no cutscene. There's also the issue that I have no save on the other two emulators, which disables me from doing the old lady glitch. Unsurprisingly, the unrelated audio weirdness occurs no matter which plugin I use.
