Re: Screen addr update on Falcon
Posted by: ggn May,21.2021-14:49 

Hi,

It's pretty much what you say, writing to vbasehi/med/low has immediate effect on Falcon, like for example when you write to the video base pointer on STEs.

So yes, on Falcon you pretty much need to set your screen pointers inside the VBL, and make sure that you're pointing to the "drawn" frame, not the "under construction" one. This means that your pointer swapping strategy needs to change slightly or in general be aware which address you're loading.

Anyway, this is trivial stuff so I shouldn't make it seem more difficult than it actually is :)
