I ripped these sprites from the SNES Starfox. Maybe you could use these as the HUD.

It's possible to rip SNES sounds and samples with SSOR95.exe, which takes the ROM files and rips all of the soundbytes and stuff.
Here's a link to it.

All you have to do is download the Starfox ROM, put it through the program, and you'll get quite a few samples, those are all of the samples in the game.
As for N64, I am not sure yet. I'll post a new post when I can figure out how to rip N64 sounds.
