Check for a section called [Debug] in your SFC.INI file.
If it doesn't exist, add it to the bottom.
Then, underneath that, add VollyInfo = 1
It should look something like this:
[Debug]
VollyInfo = 1
FPS = 1 (<- if you want to have your framerate and game speed displayed in the upper right hand corner...)
Or just get the KhoroMag utility...
