He/she/it is probably confusing Sin and Punishment (the first one, which is a N64 game) for Sin and Punishment: Star Successor (the second one, which is a Wii game) or maybe thinking only about the VC release. One can always play the first one on a N64 emulator. No need for a Wii or Wii emulator emulating VC games.
In my opinion, just do the N64 version. The difference between the N64 and the VC release is really minor (menu translation). With some basic knowledge of probably katakana (haven't played the Japanese version), anyone can navigate the menu. If you have the VC version, try to work some magic with the Dazzle (or whatever) to get decent quality video and hope it gets accepted.
