Graphics problems:
- tearing in the main road (tile layer 3 offset?)
likely cause is mame/video/taitoic.c in tc0480scp_bg23_draw:
likely cause is mame/video/tc0480scp.c in bg23_draw:
** flawed calc ?? **
x_index -= (tc0480scp->x_offs - 0x1f + layer * 4) * ((row_zoom & 0xff) << 8);
x_index -= (m_x_offset - 0x1f + layer * 4) * ((row_zoom & 0xff) << 8);
- car sprites palette flickering
- layer missing sometimes (random?) ie. motor block sprite after inserting coin
