I'm playing the games I have in order of release and over this weekend I beat F-Zero and F-Zero X on standard finishing first in every race and league. I also tried to emulate the BS F-Zero Grand Prix, but could only get the Ace cup to work.

All the other roms showed a blue screen with japanese text on it and what looked like a crying robot. Weird.
So my main takeaway from this play through of F-Zero is that it I now put it on even pegging with Super Mario Kart as the best 16-bit racers and I
really love SMK so that's saying a lot.
F-Zero I find is as sharp and fast as it always has been. You don't have any of the gravity defying craziness that was introduced once the series went 3D but you do have more emphasis on tight cornering and hitting racing lines. And the controls are superb. Every time I play it it jumps another notch up my personal SNES all time great list.
My feelings on F-Zero X haven't changed which is to say it's briliant and probably my third favourite racing game ever. The sense of speed, the rocking soundtrack, the perfect difficulty and control. I'll never get tired of playing it. And I managed to beat the X Cup without the game generating an impossible to win track! Happy days.
I'll try to get the BS game working again but otherwise I'm moving onto GX and Maximum Velocity now. I've never cared much for Maximum Velocity TBH but maybe my mind will change. Hope so anyway.
