Mario Golf: Advance Tour is an RPG-styled sport game developed by Camelot Software Planning and published by Nintendo for the Game Boy Advance in 2004. The game is the sequel to the Game Boy Color version of Mario Golf. [Info from Wikipedia]
Robert Seddon has recorded an interesting video about some of the debug rooms and unused areas that can be found in the Mario Golf: Advance Tour game code thanks to the Atrius’s Golden Sun: The Lost Age editor (as both games use the same engine). We can even notice some GBC-alike sprites, probably used as placeholders. The beta” foyer had some different details as you can notice from this comparison:
Robert Seddon has linked us to an interesting topic in the Golden Sun Hacking Community Forum, in which they have found a lot of unused items, sprites and Psynergy spells that were still hidden in the Golden Sun: The Lost Age code! All of these can not be obtained in the final game without hacking. Betweem the unused NPC there’s one that looks a bit like Link from The Legend Of Zelda and we can only wonder if it was going to be a cameo from the Zelda series, later removed for some reasons. Also several characters from the original Golden Sun are among the game’s sprite collection despite not actually appearing in the game. Maybe these sprites are still in there because the developers used the original Golden Sun code to build the second game and they just forgot to remove that old stuff.
