Nope. I think less than a handful of games can use both monitors at the same time.
Also, I'm looking forward to your Multi Vs Lite kits and your planned ROMS. Please note that as far as I know, Vs SMB can only be inserted on one side of the PCB at a time, and on a specific side (depending on if it's in a Unisystem of a Dual System). The Unisystem also requires a dummy chip installed on the other side (or some other hack) for SMB to work.
