Exodus: Journey to the Promised Land
From Sega Retro
Though the games do have a TMSS check, they will only do the $A14000 write if they detect the region of the console they are running on as US — therefore, the games will only boot on either any US Mega Drive or on any other Model 1 Mega Drive without TMSS (making that a partly useless form of region lockout).
Gameplay of both versions is identical: you are the main character (Moses or Joshua, respectively) and you must collect all the bags with M on them (Joshua: coins with $ on them) scattered throughout each maze. and shoot; you can hold them down for rapidfire. Shooting destroys blockades and enemies. Once all the M bags are gathered, find the exit to move on to the next level. In between each level, you must answer a bunch of questions related to the story of the Bible of the game's theme; getting them wrong appears to be inconsequential to the outcome of the game (this needs investigation).
