Hello, thanks for the answer.
Yes I know that it was a pre-release, it was labeled so as you said
.
However, I tested the 2020.03 before that and I got the same problem.
The rig is as following:
GFX card is a ATI radeon HD 4350. ( I bought it cheap and also because it had support for 15khz and atom15 firmware)
Dell Optiplex 7010. core i5 with 16gb of mem, nothing special.
It is going in to my Arcade cab with a CRT tube, CGA only supports 15khz with a max of 624x200.
The harness is Jamma and I'm using JPAC to connect to my computer. supports 15khz and 31khz.
I'm currentlly having another computer running windows xp with groovy mame, which i'm not really happy with. It works but there are alot of quirks that I don't like with that setup.
Anyway, I'm trying to configure this on my bench with my LCD that supports this resolution and 15khz via vga.
And rebooting computer with the atom15 firmware i get a picture but when attracmode is starting the resolution is switched.
If I exit to gasetup the resolution goes back to the 15khz 320x240 which is the one I want.
So how do I force the resolution to be the I want ?
Shall I connect to the real monitor and re-run anything that may generate new resolution settings ?
Edit anything to force it to use 15khz monitor ?
So for me there is no great way to get this to work. Going back to the 2018 image is no good as it freezes the attracmode,
going forward I get the problem with resolution.
Any ideas are welcome. If you have a hack, I can try that to.
Best regards Par
