I had an installation of RISCOS for my Pi3 (that I struggled to put together ) that works OK. I thought to update it. I took the latest nightly riscos.img and overwritten the existing one in my SD (in the FAT area).
Unfortunately it booted to a 640*480 screen that I had no menas to change in 1080p since the list of monitors was containing very old models. Even changing to an intermediate resolution I was getting an error that changes could not be saved.
Is there a more correct way to update my RISCOS installation?
I tried a new installation using the RC15 that claims to be Pi3 compatible...it booted NOOBS but I never booted RISCOS
PS1:And while I am here...I cannot understand the download of files in NetSurf. A pop up with a progress bar pops up and when it finishes and stays there. If I attempt to close the pop up window, I get a message saying that downloads are still running, am I sure I want to quit.
