This trick will only work on Sega Megadrive/Genesis.
To do this, first put in Sonic 2 and go to options.
- Then go down to sound test and do the level select code (19, 65, 09, 17).
- Hold down 'A' button
- CAREFULLY take the Sonic 2 cart out (it should still have the options screen showing)
- Put in Sonic 3 and press the reset button
- When the Sonic 3 logo shows up, let go of the 'A' button
- Press down till you get Sound Test and there you go! (A + Start for debug mode)
NOTE: I AM NOT RESPOABLE IF YOUR CARTS AND/OR MEGADRIVE IS DAMAGED AFTER THIS TRICK!
I have done this MANY TIMES before on two different Megadrives and carts
