+ TODO (xsedae):
+ - sprite DMA params doesn't quite work well with this and zeroteam (hardcode src to 0xf000 and size to 0x800).
+ - sprite ROMs are badly dumped (half size);
+ - sprite X kludge needs to be removed somehow;
+ - apparently the only real usage of the sprite protection in xsedae is on the field map (sprite goes in the wrong direction);
+ - text tilemap has color issues;
