The error given at the end seems the most relevant. One person reported a similar issue on the MelonDS repo:

https://github.com/melonDS-emu/melonDS/issues/1116

I will try with desmume and see if I get the same issue or not.

[awmc000]

It actually runs and even loads instantly with Desmume. I will post this over on the MelonDS repo, but I will leave it here for you to decide if it is relevant to your work on the engine.

Are you using devkitPro or BlocksDS? DevkitPro has an issue with the way nitroFS reads from the cartridge in emulators: https://github.com/devkitPro/libfilesystem/issues/2

BlocksDS should be okay.

[AntonioND]

This issue isn't related to Nitro Engine, so I'm closing it. This is a link to the melonDS issue: https://github.com/melonDS-emu/melonDS/issues/1669

It may be needed to open an issue in the BlocksDS/sdk and devkitPro/libfilesystem repositories.
