In other words you can create earthquake effects with Z-Address. It is used in both Reuben Quest games as well as Illusiat 2004, ROL3, Zelda DLQ and I think ROL2 used it too. You can also have vertical smooth scrolling effects. That doesn,t work well in WabbitEmu. Sometimes it does, like iN Reuben Quest battles, but some other times it doesn't. Plus this isn't recorded by the screenshooting. PTI supports it well, though
