This update fixes the ROZ effect in Namco NA1 driver.
ROZ tilemap is actually an additional tilemap. The prior implementation conditionally applied ROZ effects to one of the existing tilemap planes. The ROZ layer tilemap contains 32x32 tiles, and immediately following videoram for the other 4 tilemaps. This fixes a bug where a "roz enable" test was causing a normal layer to be rendered with ROZ effects in-game. There is no roz enable register - it's always available for mixing with other tilemaps and sprites This also adds a missing NAMCO logo zoom/spin effect in Emeralda's attract mode. Also added to this driver (but not enabled) are notes regarding a missing scanline IRQ effect, that is the root cause of a bad priority effect in Emeralda attract mode, where a dolphin sprite is incorrectly invisible.
