Help with my minigame - scrolling of the top rows is not smooth

Hi, we're writing a mini game for the SMS.
We've leaned a lot since we begun working on it. No we have added the tilemap to the game and it works - mostly. But we are getting this "jumpy"/"shaky" problem at the top rows of the screen. The whole screen is updated in one single loop, but the first rows behave differently - the bottom rows ork perfectly. The problem happens whenever e move the soldier, in any direction. In other words, the problem is not caused by horiontal scroll itself. The exact same problem happens, even if we move the soldire vertically. The problem can be seen in the videos below: https://youtu.be/0ProlHbGFFA https://youtu.be/jZYMhIWve0I Thanks a lot! |

Have you tried running the game in Emulicious? You can use the debugger there and check what's happening. | |

how do you refresh your map ?
you need to update/push only a col / row at a time not the full map as its impossible because too big to fit in 1 vblank ; 32x24x2 = 1536 bytes, max i s around 1000 on SMS ntsc 60hz. |
