over and over. This worked well on over half of the opponents. For others, I would crouch and mash 
to do a sliding kick. This worked well on a handful of opponents too, especially Karai at the end. Those are the only two moves I used the entire playthrough, but just be aware you can't always just spam one and that's it. You can try, but if it fails and you take huge damage, use the Rewind feature with 
and try a different tactic (jump away, slide kick instead of staff, or vice versa, etc.) until you find something that works, rewinding over and over. Rounds go pretty quick, so as long as you can do more damage to them than they can to you, you can jump around to try to kill time to win that way.
to bring up its Enhancements. From this menu, make sure to turn on Playable Bosses, Ultimate Attacks in Story Mode, and Max Speed. Launch the game and go to Options. Make sure the rounds are set to 1, speed is highest, and the Difficulty is set to 8. This last thing is most important, because the "real Karai" only shows up on the final boss if you're playing on the highest difficulty.

Introduction:
Welcome to Teenage Mutant Ninja Turtles: The Cowabunga Collection, a collection of all 13 TMNT games from the NES, SNES, Sega Genesis, Game Boy, and Arcade, together in one bundle. Like many of these collections, there are extra features added, all of which make the games more accessible and easier to play and complete. However, for those going for the completion, you can abuse some of these key features to make most of this a walk in the park. Get ready for some serious nostalgia, and let's get started.
Abbreviated Walkthrough:
There are 13 achievements and 13 games - one achievement for beating each game in the collection. For 11 of the 13 games, you can make them all trivial by exploiting the "Watch Game" feature. The only two games this can't be used for are Tournament Fighters (GEN) and Tournament Fighters (SN). This DOES work for Tournament Fighters (N). Essentially, you can watch the game being completed until the end, then start the game from the last moment before it's beaten, beat it yourself, and get the achievement. Refer to Gnarly Greatness (70G) for all of the exact steps you need to do to make this exploit work, as it's not just as simple as jumping in right at the end. This will make each game take a minute or so to complete, for those 11 games.
For the remaining two games, you have to do a bit of work to get those achievements, but it isn't too bad considering you can still use other features to help get through them. Refer to each individual achievement in the guide for the steps to take to make those achievements as easy as possible. That'll wrap up this completion.
Conclusion:
Tons of really good games in this collection, but if you're just going for the completion, you likely didn't play much of them. I highly recommend at least enjoying the arcade games after getting this completion, because they're a lot of fun in co-op with friends. Hopefully you enjoyed the trip down memory lane, didn't get too frustrated with the fighting games, and got this completion in under an hour. Congrats!
