I got a Problem with my Overworld HDMA disappear after reentering a Submap where the HDMA is on.
Furthermore: I tried it withouht any HDMA and I notice that when I'm on a subworld the BG is (light blue/white) and when I reenter it automaticly switches to black.
Here without HDMA:
Here with HDMA ( I disabled the border in the emulator so you can see the problem better):
I tried to do the whole Pallet black to check which color is the (light blue/white) but it seems that the (light blue/white) is not in the pallet but in the code somewhere.
For testing reasons I unpatched every patch I have in the game but none of my Problems got fixed.
As you can see in the video there is also a lag between changing the Subworld (seen by mario stop moving in the top left). No idea where this problem comes from. I tried using a clean rom with no patches but the lag comes as soon I edit the Overworld so I think my color Issue has something to do with this Issue too. not sure though.
I would love if someone could help me, thank you very much <3 <3 <3
