Well I just replaced a few stages with truly awesome SSE stages and I can't quite enjoy them with the NPC's truly horrible AI always hitting the sandbag, not to mention it annoying my friends too.
Is there any way to remove the sandbag in online training?

NTSC-U only.....(I think)
Orrrrrrr, you could swap the itemgen.arc in WiFi room with one from another stage, it will now give it regular items as well. If it doesn't work for you let me know.
