Bug fixes for NamcoNA Hardware:
- 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)

To Do:
|
||||
|
||||
- Pressing "F3" (reset) crashes MAME
|
||||
|
||||
- Emeralda:
|
||||
After selecting the game type, tilemap scrolling is briefly incorrect
|
||||
The demo sprites are incorrect, you should see a dolphin speaking
|
||||
the instructions and the playfield is wrong.
|
||||
Byte 0x25 of the NVRAM controls the FBI logo. 0x00 is on, 0x01 is off
|
||||
|
||||
- Hook up ROZ registers
|
||||
Example: In Emeralda the game logo rotates and zooms in against a black
|
||||
background with bubbles during the intro. Then at the second green screen
|
||||
when flashing Please Insert Coin, the word NAMCO rotates past the viewer.
|
||||
|
||||
- Is view area controlled by registers?
|
||||
- view area / screen resolution controlled by registers?
|
||||
|
||||
- Xday 2:
|
||||
has some graphics glitches (wrong sprite tiles); probably blitter-related
