Nope, made the font from existing soundfonts, combining sounds, converting the stereo wave into a mono 8-bit wave -- I was trying to make a small soundfont I could use with Game Maker. It turned out to sound like something from the GBA. lol
The snare drum is indeed from Pokemon. I visited one of the Sevii Islands and a drum solo played, and I snagged it. I wasn't planning on it, but I can get together a quick soundfont that can replicate that of the real Pokemon RSEFRLG soundfont... Give me a minute or two and I'll see what I can do. : P
