I'm very sorry jdaster64, but I have tried everything to try and beat level 6-5 in Super Mario Bros. 3 without using the Tanooki Leaf or Tanooki Suit, and I was unable to beat it. I even resorted to try manipulating the wall-jump glitch, but it didn't work out. Again, I'm very sorry.
That's OK, it might be possible, but probably would take more timing than beating Tubular with no powerup, Yoshi, or P-Balloon. :P
Also, FBMardio, I own a very limited selection of games, and a only so good at most of them. (e.g. I haven't even cleared Very Hard Classic on SSBM without a continue). The games I listed on my thread are the only ones I coud probably take requests for. Sorry...
