I know that there’s been activity in the emulation scene around “extending” the SNES emulators with features the SNES never had during its lifetime, like CD-quality audio aka the PSX, or hi-res texture packs, or faster + higher-resolution poly rendering for games using the SuperFX chip; and there have been ROMhacks and home brew that take advantage of these extensions.

Has anyone tried doing the same for the N64? Seeing what would be possible for an N64 game given an emulator tweaked to allow an unlimited ROM and VRAM size budget and (effectively) zero DSP DMA delay?
