How To Make SNES Sound Effects?

[Neon Streak]

Oh yeah, another thing I wanna do is make my own SNES instrument samples-by that, I mean from scratch. I know for a fact that the SNES's sound chip could play compressed and/or uncompressed 16-bit .WAV files, but I'm having trouble finding samples to work off of. For example, I wanna create my own 16-bit guitars, however the only ones I can find are riffs (Multiple notes.). That's not what I want. I'm wanting short, single-noted, 16-bit .WAV samples that I can loop with FL Studio's DirectWave.

Anyone got suggestions?
