I am not sure about the relationship of this wiibrew application with the ash's cap and guitar axe HDLCs (i.e. you need to install/insert them to savegame file using PC application, EZ_DLC_Install). You cannot get those specific HDLCs using DiiLC.

Nevertheless, tell me more which Wiimote button did you push when running DiiLC application? And what information did you see on the Wii screen when you run DiiLC?
