Since I have planned to play Street Fighter II' Champion Edition on the PC Engine as a comeback to Longplaying, I booted up the PC Engine emulator that's used for the other LPs I did here (Emulator is a PCEjin emulator gotten from TASVideos), and alas, it lacks a 6 button setup. (Yes, PC Engine pads can have 6 buttons on its pad.)
Magic Engine has it, but no recording possibilities.

Playing Street Fighter II with a 2 button pad just doesn't flow with me. (RUN - L.Attack, II - M.Attack, I - H.Attack)

When I tried to set the controls, I noticed that it had boxes for "X", "Y", "L" and "R", which I think is some leftovers from a SNES emulator or something.

My comeback hampered by a small crimp in the PCEjin emulator... Let's hope someone'll fix this small problem soon.

Welcome back, long time no see ;)

try Magic Engine!

Like I said, Magic Engine doesn't have a proper recording thingamabobbie like PCEjin has, and I use savestates to hide the fact that I suck at fighting games. ;-)

Dont think there is a way around this, if you cant play with 4 buttons, just record another game :)

Hm... Looks like I can play Super Street Fighter II Turbo Revival on the Game Boy Advance instead - as long as I stay away from the dreadful, game breaking Akuma glitch.

I love and am used to keeping a distance with those changed things.Only in this way can I know what will not be abandoned by time. Forexample, when you love someone, changes are all around. Then I stepbackward and watching it silently, then I see the true feelings.
