You could always get your hands on the RetroN 5 console.
I think you missed the part where I have a working NES, SNES, etc...
If you ever actually wanted to do Haunted Castle, there's that Japanese PS2 release of it. The emulation's pretty wonky on it, however.
Ahh. That is what I must have been remembering, it being included in a collection on PS2 but I guess it's only Japanese. I DO have the equipment to play imports, just would need the game. There is no way in hell I would be able to beat it though.
