game only works with sd card in
I have a rather odd problem. I just modded a new wii using the excellent softmod instructions for 4.2 on this site. All went well and everything works great. I tried playing a copy of Super mario bros and it wouldn't work. I tried a few times, then all of a sudden it was working. I discovered that the time when it worked I had left the SD card (with all the softmod files) in the slot. It won't work without it. I'm just curious as to why this is? Also, it is my daughter's wii, and I would prefer not to give her access to the HBC in case she does something to brick the wii, so I would prefer to take out (or reformat) the card. Is this possible? Maybe there is something on the card I need to install? Thanks for your input.
I think it depends how you install USB loader GX, you can partially install it which requires the SD card to be in at all times or do a full install.
I believe you install USB Loader GX-UNEO_Forwarder.wad
