How can I see DosBox Error on Switch?

I tried to run old game name is ForTheDay3 on switch but it’s not work.

It’s supported 100% on Windos(DOSBox version: 0.72) but not on switch.

How can I check the problem? or Someone can check it?

DosBox supported page.

thank you.

Where to report error about Retroarch DOSbox core for Nintendo Switch? I found an error with mounting CUE+BIN+MP3|OGG|WAV (CUE+BIN works fine, though.
