Does the screen go blank or do you get to see the "You'll need the classic controller" screen?
actually i was getting both. i just tested some more and heres what ive found. i tested all 4 of those games 5 times each using 247.
smash bros, paper mario, and kirby all loaded like 4 out of 5 times just fine... so i guess using 247 does work.. just not perfectly it seems..? but i can live with that if thats the case.
majoras mask on the other hand doesnt work AT ALL. no matter how many times i tried it using 247 or default(249).
edit: ok well i tried a different copy of the majoras mask.wad and got it to work. just like the others, it will load up like 4 out of 5 times correctly. which is good enough
for now. heh.
