This is an ASM hack of Pokemon Gold that reintroduces all the Generation 1 music, plus a whole slew of new songs specifically for this hack.
While this hack has relatively few changes outside of music, it does have a few noticeable/inevitable changes.
-The Bug Catching contest has a boosted encounter rate due to the map music's inclusion with encounter rate multipliers.
-Kanto's map music is closer to what it was in RBY.
-(ASM version only) You can talk to Jigglypuff at the Radio Tower or the Pewter City Pokemon Center and hear the Jigglypuff jingle from RBY.
-The Magnet Train now plays the new Pokemon Channel music. (Though this started as a mistake, I kept it in because it fit.)
-The cry distortion bug has been entirely fixed. Each cry that was possibly susceptable to this bug had "pitch_sweep 0, 8" amended at the beginning.
-The NPC-trades boast better nicknames for Pokemon, such as Brent, Capper and Sandy.
-Brent's Bitter Berry was replaced by a Metal Coat, but he doesn't evolve when you get him.
If anybody wants to build this hack, feel free.
