Homebrew Nethack black screen M3 Ds Real

[Mcstan]

I'm trying to install the nethack homebrew port (found on gamebrew dot com) on my nintendo Ds Lite. I have a M3 DS Real with the M3G6_DS_Real_v4.8c_M69_Multi firmware.
I copied the nethack.nds game and nethack folder in the root folder of my sd card, the game software is stuck at "creating a save file. Please wait".

Has anyone managed/ or has tips to install this game correctlyor other homebrew games on a M3 DS real ?

Can I see a picture of your M3DS Real card? Fake cards do not seem to work with the official kernel.
