If you set it up correctly, you should be able to simply double click on the executable and it will come up with a file selector from which you can select the game you want to play. I.e., create a subdirectory called ROMs that lives at the same level as the VJ executable and put your ROM images there. You can edit a few options in the vj.cfg file such as whether or not to use the DSP, plus some others.
