+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.
