I'm trying to add custom music to NSMBDS and I used this amazing guide (https://nsmbhd.net/thread/475-tutorial-nsmb-sound-and-music-hacking-guide/) but when I try to run this command in the command prompt:

midi2sseq Train-rush.mid

It tells me that "The code execution cannot proceed because libgcc_s_dw2-1.dll was not found. Reinstalling the program may fix this problem."


Then after I close that window it says "The code execution cannot proceed because libstdc++-6.dll was not found. Reinstalling the program may fix this problem."

But the program is a single executable wherever I look to download it. Is there some solution i'm overlooking?

You can download those two .dll files (you can find them by typing those .dll file names to Google), and place them in the same directory where midi2sseq.exe file is.

Thanks, this helped very much and even would've fixed the problem if there wasn't a new obstacle in my path. Now there's a message in the command prompt saying saying "Error: Invalid MIDI file!" I tried doing the instructions all over again, and got the same thing.
Is there even a way to solve this? (For the record, i'm using a .mid for Train Rush from A Hat in Time that uses 2 channels out of the channels used in the athletic theme, none added, none removed, the unused ones are just blank. It was also this way the second time.)

Open the midi file in Cakewalk Home Studio and remove the very first track, which should be empty, and then save it.

Can't seem to find a way to get Cakewalk, but I do have FL Studio. Will that work?

Any MIDI editing program should work. I use Anvil Studio, through

Got rid of the very first track, still got the very same error.

using anvil studio, export the midi as a MIDI-Format 0 file. it'll work.

Redid the entire instructions, used Anvil to remove the first track, exported as MIDI-Format 0, and it STILL isn't a valid MIDI. I think I should just quit trying and move on with the hack at this point.

Simply use Nitro Studio by Gota7, it is an awesome DS music editor.

It has built in Midi2Sseq so you can just export and then import.

To edit the MIDI you can use Anvil Studio

There's this newer tutorial:
https://nsmbhd.net/thread/4507-updated-music-hacking-guide-for-new-super-mario-bros/

Also Gota7 and I have been working on a guide, but since we're both busy with other stuff as well and Nitro Studio will get some updates first, we haven't been able to finish it yet.

It worked! Thanks!
