Command line options:

     By  typing:  SF2  /help [ENTER] you get a help screen telling you
about  two  command  line  parameters not mentioned in the manual. SF2
/updownmove  is the handiest; with this parameter activated the screen
scrolls  vertically  as  well  as  horizontally  -  meaning  you don't
disappear  off  the  top  of  the  screen  when you jump. The other is
accessed  by  typing  SF2 /vesa105 which runs the game in 1024x768x256
colour mode 105 on a VESA SVGA card.

Cheat:

     If  someone  (Dhalsim  maybe)  keeps  beating you select a strong
player at the start of the game. Then once you've beaten the character
that  you  usually  can't beat let the person after that defeat you to
get  to  the  player selection screen. Don't press [Spacebar] but with
the  cursor  keys  select  the player that you can't complete the game
with.  You  can now finish off the rest of the characters and complete
the game.
