Ok its work great now, But it would not compile until I removed a line from the VIDEO_START code.
VIDEO_START( multipac )
{
init_save_state_multipac();
charbank = 0;
spritebank = 0;
colourbank = 0;
flipscreen = 0;
bgpriority = 0;
/* In the Pac Man based games the first two sprites must be offset */
/* one pixel to the left to get a more correct placement */
xoffsethack = 1;
bg_tilemap = tilemap_create( multipac_get_tile_info, pacman_scan_rows, TILEMAP_OPAQUE, 8, 8, 36, 28 );
tilemap_set_scrolldx( bg_tilemap, 0, 384 - 288 );
tilemap_set_scrolldy( bg_tilemap, 0, 264 - 224 );
return 0;
}
