as a HUGE fan of the original pokemon soundtracks, you took my right back to when i would obsessively turn on GB sounds in my pokemon ds games so i could hear all those lovely lil chiptune vibes, and you captured the spirit of that gameboy style pretty much perfectly! Stylistically I think you did a brilliant job with all the tools you had available to you, sticking to the GB soundchip is a pretty big challenge and I think you used it incredibly well, to the point where i would encourage you to try even more to push it and mess around with maybe some gliding and vibrato effects if thats at all possible, because it could really bring you skills on this from great to perfection with that little extra personal flare! My only complaint is that i think the lead is a bit quiet in the battle theme, but other then that you really blew me away with this. Well done!
