Here's another idea I had: Patches for the original Mario Party N64 Trilogy (especially the first two games which gave Luigi, Peach, Yoshi, and Wario different voice actors from their standard voices) that replace the voice clips of Luigi, Wario, Peach, Yoshi, and Donkey Kong with those provided by their respective voice actors from Mario Party 3-5, with DK's being provided by Grant Kirkhope of DK64 fame. They should also work with the NSTC-U versions to differentiate them from the NSTC-J versions.
