Well. Then it seems like you scribbled yourself some magic! :-)
The voice at 0:15 almost sounds NES-like when it starts (but still works stylistically) but it evolves over the piece into something that, when in the middle register made me think of the plucky guitar from "Into the Thick of It" from Secret of Mana [albiet "chipper"]. The "Organy" lead that has the melody before the "chipitar" takes over reminds me of some early SNES game that I can't quite pin down. And my absolute favorite sound in the whole piece is that weird, but wonderful bass. I can't even think of how to describe it, but I hear it in wavetable tracks from time to time, and it's a magical, hallmark wavetable sound to me. It almost sounds like what I'd imagine some of the Galaga ship blow up sounds would sound like if they were pitched that low. And then top it off with white noise that almost sounds like Atari 2600 (or at least periodic noise on an SN76489) and the whole thing just locks together with amazing result.
But all that aside, even if these waveforms were just scribbles, they were still custom waveforms. They were not your garden variety saw or pulse waves that seem waaaaay too common on a system that could just as easily do soooo much more!
PCE sometimes gets a bad rep for sounding "12-bit", and the sad thing is that there is enough underuse of the chip that I understand why it gets the rep. But where people go wrong is in assuming that's all the chip is capable of. I love tracks that show its greater capabilities.
It's between Wavetable and FM for my favorite sound in video games right now...and at the moment, I think I might actually be leaning Wavetable. So, on the one hand, that makes me more critically minded in how it's used, but it also makes me super appreciative of excellent uses of the chip.
Keep up the great work, Beard!
Also, can you send me a link to what you used to make this? I may want to start playing around with it, especially if you can draw your own waves.
