Just did these hacks for DieHard and created a thread to document how I did it so I won't forget again if I go another 8 months without practice. Anyway, this game isn't so bad once it's playable. I saw it on an episode of AVGN and that spurred me to even the playing field as it looked interesting.

Did some hacks on this to see the end of the game after 27 years. Could NOT beat this in my youth and after working through it with infinite health, doubt I ever would have-given the amount of enemies and cheap deaths I witnessed

Below is the magic combination I found to work the best. Things like Invulnerability wouldn't let you disable bombs on the Dam (stage 2) so didn't really work effective for getting far even though it was nice not to get knocked back by enemies for a while there.

Keeping with the turtles theme, here are some hacks for Teenage Mutant Ninja Turtles II - The Arcade Game (USA) that make it almost playable :p Never saw the end of this one either and although there was a little more to it than the first game, hardly worth the effort-like most NES games. Was glad to finish it after 26 years though

You hacker, you! LOL

Yep, fun stuff. I like hacking the rom more than inputting Game Genie codes. I know if I ever return to one of these games it'll be to blaze through and not to test my skills or get good at them again

Some of the codes won't let you get through the game and others don't work the way as intended but here's at least infinite candle power and infinite lives to 'help' get through this game.
