Moonshell not loading

I have a n original R4 with a 2GB kingstone (formatted).
Moonshell (the latest stable version) worked fine until I reinstalled the modified YSmenu to fix the ML:BIS anti-piracy,
but then when I try to load moonshell (as a .NDS file) it gets stuck, not even showing any signs of loading.

I only use moonshell for mp3 playback, will a lower version work (can't test it until tommorow) or do I need to revert back to an unmodified version of YSmenu for moonshell to work ?

3D Picross (J) problem

After downloading the 18th puzzle pack suddenly I can't play them anymore, when I'm trying to enter the cutom puzzles I get a message and have to reset my DS. It started as soon as I solved one custom puzzle.
Does anyone know what the problem is ? (I'll try getting a screenshot).

Rittai Picross extra wi-fi option question.

I noticed when I download new puzzle packs that there is another wi-fi option, a green button with a cup picture in it and when trying to access it I'm not getting anything.
Does someone know what is that option ?
