MiSTer FPGA Forum

I have a folder with wallpapers, and sometimes my MiSTer displays one of them randomly as expected. But sometimes it just shows a chequered pattern, as if the file is missing.

The images are all PNG 1920x1080. I've tried cycling between the different background options with F1 on the keyboard, but it doesn't remedy the problem.

Does anyone know what could be the cause of this behaviour?

I only use JPG and it works fine. Maybe try to shift to JPG

Are they on the SD card, or have you moved them elsewhere? Wallpaper and font files really need to be on the boot drive so that they're immediately available when the menu core starts.

They're all on the SD card, so that shouldn't be the problem.

I'll do a test with JPG. Thanks.

The checker pattern coming up probably means that the file is either corrupted or invalid in some way. Can you try and rule out which file it is and then attach it here (filename intact and everything) please?

There's a few to go through, but I'll give it a try.

A possibility, albeit kind of a remote one, is that your SD could be failing. They do that, especially low-quality or counterfeit ones. Be alert for other I/O-type issues; if you start seeing those, SD failure moves way up the list of possible explanations.

I migrated to a brand new Samsung Pro Plus 256GB card only 5 days ago, so that’s most likely not the explanation. And the behaviour was the same on the old card as well.
