Managed to find another of my universal power supplies so I could power up the Subor SB225-B and my Composite to VGA adapter at the same time, and then fetched one of my monitors that I knew could handle the resulting video signal. Looks like everything is working great!

My NTSC-J Famicom games will boot, but they don't fill the entirety of the screen and they run slow. I suppose some titles probably won't work at all.
