World Cup 90 bootleg driver
---------------------------

Ernesto Corvi
(ernesto@imagina.com)

CPU #1 : Handles background & foreground tiles, controllers, dipswitches.
CPU #2 : Handles sprites and palette
CPU #3 : Audio. The audio chip is a YM2203. I need help with this!.

Memory Layout:

CPU #1
0000-8000 ROM
8000-9000 RAM
a000-a800 Color Ram for background #1 tiles
a800-b000 Video Ram for background #1 tiles
c000-c800 Color Ram for background #2 tiles
c800-c000 Video Ram for background #2 tiles
e000-e800 Color Ram for foreground tiles
e800-f000 Video Ram for foreground tiles
f800-fc00 Common Ram with CPU #2
fd00-fd00 Stick 1, Coin 1 & Start 1 input port
fd02-fd02 Stick 2, Coin 2 & Start 2 input port
fd06-fc06 Dip Switch A
fd08-fc08 Dip Switch B

CPU #2
0000-c000 ROM
c000-d000 RAM
d000-d800 RAM Sprite Ram
e000-e800 RAM Palette Ram
f800-fc00 Common Ram with CPU #1

CPU #3
0000-0xc000 ROM
???????????

Notes:
-----
The bootleg video hardware is quite different from the original machine.
I could not figure out the encoding of the scrolling for the new
video hardware. The memory positions, in case anyone wants to try, are
the following ( CPU #1 memory addresses ):
fd06: scroll bg #1 X coordinate
fd04: scroll bg #1 Y coordinate
fd08: scroll bg #2 X coordinate
fd0a: scroll bg #2 Y coordinate
fd0e: ????

What i used instead, was the local copy kept in RAM. These values
are the ones the original machine uses. This will differ when trying
to use some of this code to write a driver for a similar tecmo bootleg.

Sprites are also very different. Theres a code snippet in the ROM
that converts the original sprites to the new format, which only allows
16x16 sprites. That snippet also does some ( nasty ) clipping.

Colors are accurate. The graphics ROMs have been modified severely
and encoded in a different way from the original machine. Even if
sometimes it seems colors are not entirely correct, this is only due
to the crappy artwork of the person that did the bootleg.

Dip switches are not complete and they dont seem to differ from
the original machine.

Last but not least, the set of ROMs i have for Euro League seem to have
the sprites corrupted. The game seems to be exactly the same as the
World Cup 90 bootleg.
