Welcome to the FX codes
Blue codes are old, they can be found everywhere or in a few places.
Red codes I've found in mags and sites but I can't get them to work. (they are probably fake)
Green codes- I don't have this game so I can't test it.
Orange codes are discovered by me, you might find them elsewhere but they were here first.
Sonic Spinball
In each stage of this game there is a secret room with a odd looking monitor, each one gives you a message as follows
Put them together and you get a new code
0,8,3,1,7,1 - The monitors give you a new message
"try these sfx (gives you the numbers below) try to find the rest on your own"
0,2,1,1,6,6 - Large Sprites
0,4,2,5,5,7 - Fast Music
0,9,0,1,6,8 - Drag & Drop (Start,2 during game to activate)
0,2,1,5,6,6 - Skip to Boss (Start,2 during game to activate)
(the rest? there has to more codes, but what do they do, I'll try as best as I can to figure this out)
