I looked around and this seemed to be best place to post this. Apologies if it's not.
When I load a utility such as the RAM test, I briefly see some video but then I get nothing. I can't even see the OSD if I try to bring it up. I know the core is probably functioning even though it's a black screen because if I do they keyboard strokes to bring up the OSD and then navigate to the reset option, I can get back to the main MiSTer screen.
My only guess is that it has something to do with where I'm using video mode 14 for 1440p video output. I could very well be wrong but that's my hunch. Can I set a separate video mode for a utility core? Something like..
[RAMTEST]
video_mode=8
???
Edit: Yeah, so I set the video mode to 1080p for everything and the RAM test displayed just fine so it was an issue with 1440p. How do I set the utility core to it's own video mode?
