as the title says whats the very 1st game you can remember beating..this is without cheats or shortcuts. so yes the mario tubes to world 8 count as a cheat..up down left right hold A and hit start is a cheat..imma also add in Contra 30 extra lives kinda made it too easy.
for me? it was the 1st donkey kong county. i beat it when i was 7...i think...
