To have two separate games of either the game gear titles "Sonic Drift" or "Dr. Robitnik's Mean Bean Machine", press Start on the second controler at the SEGA screen of their games as you would normally. But instead of selecting "Versus" for Drift, or "Gear to Gear" for Mean Bean, select different modes instead. So in Sonic Drift, two people could be playing completely different circuts, and in Mean Bean, one person could play Scenario Mode, and the other Puzzle Mode. If you choose to return to the game title in R1 mode however, both players will reset their games.
