oh I know that for sure. I had one of those screwy mad catz controllers and the A button would get stuck....it can really mess you up pretty bad ^^;
my fave stages would have to be....Final Destination (I love those fair fights), Spear Pillar (because I'm a huge pokemon fan and the music is great), Pirate Ship (because it's my main's home turf ^^; and once again the MUSIC) annnndd Space Armada (the music is great once again, and the scenery is amazing)...well that's it for my FAVES...I have to say though...scrolling levels can get quite annoying.
it was great to fight you though! like I've already said, it's hard to come by a good Yoshi player (or ANY Yoshi player for that matter) look forward to our next one ^^
