No image anymore on 1941, 1942, 1943 and Commando

I could run 1941, 1942, 1932 and Commando perfectly well in the past, but since some time there is no image or rolling stripes on the screen (using HDMI) with these games (and probably other jotego games). Does anybody know what might be the problem and solution? Maybe it is sdram related, as I only still have a 32GB sdram card installed? But they used to work before.

It is working properly on my system with 32MB SDRAM and using HDMI.

A blank screen usually means that MiSTer cannot find the ROM files.

@jotego, thanks for your reply. At least on 1942 I see the window that loads the roms, also the games are running as I hear the sound effects and music. I used the update_all script to install everything.
In which folder should the roms be located?

I found a solution: when I toggle 'Rotate screen' in the menu, the image appears. Maybe this indicates some issue with the initialisation of the screen?
