Sauro Memory Map (preliminary)
driver by Zsolt Vasvari
Main CPU
--------
Memory mapped:
0000-dfff ROM
e000-e7ff RAM
e800-ebff Sprite RAM
f000-fbff Background Video RAM
f400-ffff Background Color RAM
f800-fbff Foreground Video RAM
fc00-ffff Foreground Color RAM
Ports:
00 R DSW #1
20 R DSW #2
40 R Input Ports Player 1
60 R Input Ports Player 2
80 W Sound Commnand
c0 W Flip Screen
c1 W ???
c2-c4 W ???
c6-c7 W ??? (Loads the sound latch?)
c8 W ???
c9 W ???
ca-cd W ???
ce W ???
e0 W Watchdog
Sound CPU
---------
Memory mapped:
0000-7fff ROM
8000-87ff RAM
a000 W ADPCM trigger
c000-c001 W YM3812
e000 R Sound latch
e000-e006 W ???
e00e-e00f W ???
TODO
----
- The readme claims there is a GI-SP0256A-AL ADPCM on the PCB. Needs to be
emulated.
- Verify all clock speeds
- I'm only using colors 0-15. The other 3 banks are mostly the same, but,
for example, the color that's used to paint the gradients of the sky (color 2)
is different, so there might be a palette select. I don't see anything
obviously wrong the way it is right now. It matches the screen shots found
on the Spanish Dump site.
- What do the rest of the ports in the range c0-ce do?
