I haven't played it in ages, but TMNT 2 The Arcade Game for the NES had the
Konami Code or a variation of it. I use to get frustrated trying to enter it before
the time was up and it went to the title screen. Also, I vaguely remember a code
for a game, but I have forgotten what the game was. The code, I believe was D.U.L.L.A.R.D.
(down, up, left, left, a, right, down). Anyone remember this? I'm pretty sure it was an NES/SNES
game but I could be wrong.
