You can't on 11.0, because there is not an arm11 kernel exploit (svchax, also called memchunkhax2.1 doesn't work). So, for now, you can't do nothing on 11.0. So, you have to downgrade to 9.2, or wait for a hypothetical arm9 exploit on 11.0 (never?). If you only want to pirate games, buy a sky 3ds+ instead.
Eventually, they will full crack 11.0 so nothing is hypothetical, its more of a "when" situation. Mods and cool stuff are still being made and discovered on the wii.
