Is there a way to simulate a CRT VSYNC in BeebEm to check for screen tear.
Is there a way to simulate a CRT VSYNC in BeebEm to check for screen tear.
I've written a grid territory capture game for my BBC Micro B. I'm using a RGB->SCART->HDMI as my display. Most frames I only moving the player blocks on the screen but when I have captured a large area of blocks I am updating significant screen memory in one call. I am not doing anything to synchronize the display memory update. I don't have a real CRT to try it on. Does BeebEm or any other tool have anyway to simulate a CRT so I can see if I need to work on improving the screen memory update?

Take a look at Tom's b2 emulator, I believe it can visulise the raster progress for debugging purposes.
