Regression spied on 0.125u1. A number of items were worked on in the driver for that version:

Bug fixes for NamcoNA Hardware: [Phil Stroffolino]
 - support for scanline effect (fixes invisible dolphin in Emeralda
    attract mode)
 - ROZ implementation no longer breaks Numan Athletics pixmap layer
 - blitter fixes; xday graphics are now correct
 - identified extra communications RAM used by xday (probably to
    control printer)

Fixed the ROZ effect in Namco NA1 driver. ROZ tilemap is actually an
additional tilemap. 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. [Phil Stroffolino]
