At the time I was specifically trying to run it on a DSi XL, not a 3DS. I haven't personally run into any other issues with GBARunner2 but admittedly I haven't tested it out deeply either. I didn't realize there were so many holes in the compatibility list, knowing that makes this issue make a bit more sense. lol. I have other systems I can load this on though so it's not a huge deal to me, just thought it was worth noting.
