Welcome back. Try this, go grab the hyperspin mame.xml and drop it into the root of attract-mode. Once the xml is in the root of attract, open a command prompt and cd to the attract directory. Now, just type in attract -i mame.xml then space emulator name. So it should look something like this c:\ arcade\attract -i mame.xml mame. This is assuming you already have your emulator created with attract, otherwise you will get error "The emulator specified was with -import was not found. So, create you emulator first.
For random game. Hit tab select configure/control then map input to select random game. Hope this helps...
