No.06284 Tafoid Administrator Jun 22, 2010, 18:20	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]

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]
