Infidelity TMNT SNES Port

Pippo · 10-13-2025, 04:51 PM

Infidelity released their SNES port of the 1989 NES TMNT game. If you're not familiar with his work, he's an SNES developer who has ported 10+ games to the SNES with minor enhancements over the last couple of years. The biggest enhancements are the elimination of slowdown and flickering NES games were prone too when there was too much going on. He's done ports for Contra, Ninja Gaiden Trilogy, Duck Tales and all 6 Mega Man games on the NES to name a few.

This is a straight port with some QOL enhancements, support for the MSU-1 enhancement chip, and some performance improvements over the NES original. If you're expecting a complete overhaul with new graphics and gameplay changes, you'll be dissapointed. However, it is a good base to modify for people that are interested in seeing the game enhanced even further.

Features Include

4 alternative soundtracks + the original NES
Two animated intros after selecting a soundtrack (TMNT '89 and Shredder's Revenge)
Slowdown and Flickering gone
The ability to swap Turtles instantly with the X button
An optional 60fps mode

I was in the beta and cleared the game a couple of times, but I haven't gotten a chance to play with the new soundtracks yet. It's a pretty 1:1 port so if you're familiar with the original, you'll be good in this version. I tried ou the 60fps mode and the controls are pretty responsive and feels better than the original, BUT the entire game runs 2x faster. The biggest issue I came across though is that the medium jump is now like a 2 frame window. It's hard to get a medium jump intentionally now, which makes the sewer section towards the end of Area 2 almost impossible. The underwater section in the dam also counts down way faster than the original making it incredibly tight to clear.

These projects are interesting, but I must admit I keep expecting the "Super Mario All Stars Treatment" and get disappointed when the color palettes and sprites don't get any more detail. Still, it's impressive that folks are dedicated enough to mod this way. I think Mike Tyson's Punch-Out!! was recently ported over in a similar way.

Infidelity isn't an artists so unfortunately he can't offer any graphical enhancements. He mainly specializes in coding. Doing a big visual revision would be a huge task for anyone though so I can see why he rather stick to straight ports with minor improvements and move on to the next one.

This is still a fun little way to revisit the NES game again if you want a smoother experience and some alternate soundtracks. I'm going to see if there's anything I can do with rom hacking to do some minor visual improvements, but I probably won't get that far outside of some portrait artwork.

At some point in the future this could be used as the base for an even more enhanced version.
