Ok have to change logo to char+map as bitmap in sb are too complex.
Now have 2 sprites on the left in sb (1st with X 487, 2nd X 0, 3rd X 344 and 4th X 368). Put three lowest bits for smooth and copy logo in memory so it moves in left and right borders.
Next is put those also in three lowest bits of sprite X registers and move sprites across X keep it 2 with every side just to logo so it will look like one "big logo".
How calculate new X positions from default?
