i have attempted undubbing both luminous arc and lunar knights. while the undubs do work, the roms are smaller than the originals, and also, after i removed lunar knights from my g6, luminous arc failed to load. i removed lunar knights because for some reason, after pairing it with luminous arc, initiating the game would lead to me playing luminous arc instead of lunar knights... and not the other luminous arc, no... it's a whole different game as my save file is missing
Edit: scratch that i got it to work after putting a dummy rom on the cart together with the hacked rom
