In addition to what is stated above, if you still have problems, do the following..
find the SFC3.exe in the game directrory, right click on the file and select properties. a grey properties window will pop up, in it, select the compatibility tab and put a checkmark in "disable visual themes"" and click OK.
afterwared try the game, if error still occurs, lower your desktop color settings to 16 bit color then try game...
if the problem is still occurring, check you system sepcifications as compared on your game box to make sure your equipment is capable of supporting the game, and if it is, then look for other drivers for your video card...
without knowing your system specs, it makes it hard to find solutions, so i kept it simple here..
Thanks, and I hope that this helps.
