If its anything like the password card cartridges I have, you flick the switch on the cart, insert a proper PS1 disc (so it reads the copy protection code from it), then it'll go to a boot menu and stop the disc spinning so you can swap it for a backup or NTSC game. The boot menu will give options as to how to boot.
Not sure if all of those video cards do the same thing, looking at that link there's only some that mention cheat code functions, but its possible that they all have the disc swap ability.
well its a video cd function, and in order to play vcds, you have to do what you have mentioned, albeit, swap it out with a video cd after the disc has spun
