I can confirm that this happens on MiSTer too.
Can you try v1.2 to see if it works
It works with 50hz PAL mode, but I just get a black screen in 60hz NTSC mode. It’s not a crash or anything, I can toggle it back to PAL by pressing the button again.
I'll play around with the video timings to try and find a sweet spot for origin hardware and fpga
