All the 8-bit tracks from the original Gold/Silver were included on the third disc of the HeartGold/SoulSilver soundtrack.Thanks, but there is no such page since the gold/silver games didn't have an official ost.
From bulbapedia:
"Pokémon Gold and Silver are the only paired versions which have not had any sort of official soundtrack release of the games' original tracks."
So I guess there is no definitive way for me to learn who composed what. Hm, strange. I guess soul silver is my closest alternative.
