Hi Everybody. Just uploading this for anyone interested. Just a past time I had started after learning Link's Awakening originally started development as a port of Link's awakening for the Gameboy.
My intentions was to fully flesh out the map using Game Maker as a tile editor while using the same map size of Oracle of Ages/Seasons, then to look into the possibility of editing a rom tile data of either of those games to play on an actual Gameboy. Have since lost interest in pursuing it further but would like to see someone utilise it in one of their own projects!
