Clearing a tiled background memor

Hello everyone
I am here because I cannot find a way to clear a tiled background I have stored in memory.
I need to clear the background map to allow the loading of another background (to move to another level in the game).
Any help would be really apreciated
thanks!

Why do you need to clear? Just load the new background over the old one.

I have tried but sometimes I get unwanted results as shifted background or game getting stuck...the problem might be somewhere else though...I will try to remove my attempts of clearing it and see what happens
thanks a lot

Techincally you could clear the entirety of the bank by re-initializing it. Another method is to simply fill in the bank with blank data, starting from the adress the background begins and of the sizeof(BackgroundYouWantToClear);, however I don't see how this could be beneficial to you.
When a new background is placed within VRAM, it overwrites the old one, and unless you direcctly access the left-over tiles in question, they should not cause you any grief.
