Ah ah you got me, I thought you made your entry using the PSG! At the same time, it seems playing simple wave through the PCM channels produces softer sounds and add a nice grain to it (when compared to Game Boy music). It really works well with the mood of your song :D

I'm a bit curious, did you make it with Maxmod? This kind of screen in your .gba ROM really looks like the Maxmod demo ROMs

@Opilion Yep. I used OpenMPT to make the song and Maxmod to port it to GBA

Besides, the reason it has simple waves through the PCM channels is because it's an arranged version of an unreleased song I made before this battle in another system (MSX with Darky to be exact)

Such a classic sound. I love the crazy seagull calls.
