I did it hard way
Oof. I found the solution on discord, my tileset name was incorrect which I only discovered by looking at the GBVM symbols.
I had the same issue: I deleted and recreated a scene, but it didn’t change anything. Gb Studio kept the GBVM variable names in memory, so I modified them through the editor and it was fine.
Same, I expected it to regenerate the tileset name when I renamed the background, but it didn't.
