SEGA Genesis Classics

To cheat your way through this, you'll need 2 controllers. Once the game is loaded and you're on the main menu. Have second controller hold down all at the same time - (A) + (B) + (C) + , then select 'Options' with the first controller. If you input everything correctly, at the bottom of the options menu you'll now see 'Players' and 'Round No.'.

Now scroll down and change the round no. to 8, head back out of the options menu and start a new game. Round 8 should now load and the achievement should unlock. If it doesn't right away, just play through the level a bit or repeat the process above to trigger it.
