Hi, you should use
http://dehacked.2y.net/microstorage.php to upload and share input files, it's designed just for that purpose.
Some things you should do, if you haven't yet:
1) Try all illegal d-pad combinations (L+R, U+D, L+R+U... seven in total) in all player states, menus and so on you can think of, to see if you can find any oversights/glitches.
2) Use RAM watch to find player X, player Y and (if they exist as RAM variables) player X velocity and player Y velocity. (Note that similar RAM addresses tend to be grouped close together, so you can try looking for hp, score or one position variable and peering around it in memory for other useful addresses)
3) Calculate how fast the character moves in every mode of movement you can think of (walking, jumping, uphill, downhill, are there any frames of movement lost when jumping/landing, etc)
The site has some excellent resources on how to use memory search/watch here:
