Regardless, it should work perfectly with your setup and isn't a problem with the hack.

Do you mind if I ask you to paste your command line entry for this game in Hakchi? Perhaps if I can clone your setup I can finally see some improvement.

Attached is my setup for this game under the NES (USA/Europe) format using the following command line argument:
/bin/fceumm /var/games/CLV-H-PKDTD/TMNT_-_Return_to_New_York1.81-b.nes.7z

If you notice, there doesn't seem to be an option to select "RetroArch" as a core by itself. I still have to end up selecting a core for RetroArch.

I'd also appreciate some suggestions for the remaining enemies.  Here's what I was leaning towards:
-Dinosaur robot: Foot Elite
-Frog:  Green foot with a whip
-Hedgehog/Firefreak/stone guy:  Earth, Fire, and water Foot Mystics
-Sentry in level 6:  Need to fix propeller, might make it a searchlight since it already has wings
-Boulder bird from level 5: ???
-Roof leaper from lvl 1-2: Some kind of drone copter that drops down on you
-Fleakid from lvl 3: Blade from TMNT 2
-Jellyfish from level 5: ???
-Wall Crawler from level 5: ???

Once these are done, there will likely be another long hiatus as i learn how to make unique miniboss fights

Thanks for the help!
i hope more unknown enemies will be replaced as enemies from the tmnt 1987 seasons i hope casey can be playabe soon and add slash as a new enemy to replace unknown bosses


This hack is my favorite NES hack ever, since the balance adjustments to the turtles really lets each one's personality and strengths shine through. This hack makes the gameplay and character differences what they should have been all along.  My only wish is that there was an alternate  version of the hack with the original NES graphics but all of the balance and gameplay changes. I know most people prefer the cartoon related characters, but as a big fan of the original Mirage comics, I always enjoyed the bizarre original graphics. There was a roughness to the original graphics that matched the original Mirage comics' sense of strangeness and the unexpected.



Just wanted to say thank you to this mod's author and anyone who might have helped him. This mod is definitely a must if one wants to play TMNT 1989.

I'd also like to note that, while the patched ROM ran fine in Retroarch with the Mesen core, the process of patching the ROM was confusing, as I was getting a warning message from two apps (ROM patcher JS and Advanced NES ROM Utility) that the ROM's checksum did not match the one from the patch file. Of course, the ROM I used was a proper no-intro headered ROM, and as mentioned, worked fine after it received the patch. But I still wanted to mention the presence of the warning checksum message. Perhaps something can be done with the next update to make it go away.

In any case, thank you again! Great job all-around.


Most often it is a header difference, such as iNES 1.0 vs. 2.0 ROMs.
But it is possible that either you, or the patch author, had a really old ROM from the internet which filled part of the header with garbage data in the bytes unused by old emulators.
