I'm trying to use VMU Tool aka Dream Explorer. I have the DC connected to my PC via the broadband adapter, but when I select "Open PC" on VMU Tool I get this message:

"You must connect your PC to your Dreamcast with a coder's cable or a BBA, and launch Dream Explorer's binary with DC Load + DC Tool."

I have no clue what this means. What are DC Load and DC Tool? I also have the PC program "VMU TOOL PC" which I assume is needed to transfer saves, right? Someone please help me! :?
