I do! ... But I'm barely more than a lurker one around here.

Pretty cool, the only thing is that the noise channel's percussion sounds way too loud to me.
Kinda distracting from the rest of the song.

Nice! I'm gonna go grab me a copy off Bandcamp as soon as I stop being lazy and get up and go get my wallet.

Cool stuff. I've been on a quest for good 8-bit renditions of every classic Megaman series song for ages. This will make a really nice addition to my collection. Let's see if I can hobble together some constructive critique for you. The first thing that stuck out was was frame 3 & 4 of Frost Man...

Pretty cool, but it sounds more like a hybrid castlevania and megaman style.

I figured as much. Thanks for confirming it.

That's just awesome. Even without the zappy sound.
It's funny to find this since I was just talking to my girlfriend about this song yesterday.

This is probably a bit odd, and I apologize ahead of time for my ignorance, but...
Is it even possible to make a convincing pencil writing sound effect using just 2A03 excluding DPCM samples?

Actually "Cross Your Heart" isn't an unused song at all. It was included on the official OST of Rondo as a bonus and was never in the game's data. It is, in fact, an extended arrangement of the original song from Haunted Castle. That being said, your arrangement is pretty damn good. Well, ...

That's a pretty good rendition of the original. Nice work.
