On some n64 games the Emulator menu pops up... but I've ran into some... that do not give prompt, just a black screen until the rom loads ...I swear I just accessed that menu on Mario Kart the other day
It sounds like another emulator was launched prior to you using the N64 emulator and left the framebuffer in an unusable state. Two emulators that are currently known to do this are the standalone version of Stella (Atari2600) and DraStic (Nintendo DS). If such an issue happens, there's really nothing to do but restart your system, as restarting Emulation Station isn't enough.
