The directory to load the external rom on the SD card is as follows: Unlike the Virtual Console versions of Pokemon Red/Blue versions and Metroid II - Return of Samus where you can launch the colorized patched roms, this method doesn't work for this game.
Hey, I just wanted to give my results in trying to use the Luma3DS 'Enable game patching' to externally load the patched rom under the legit install Virtual Console title.
