Re: 240p on HDMI

Look at the example in the mister.ini for 720p: video_mode=1280,110,40,220,720,5,5,20,74250 Try the following parameters for 240p (if you have FullHD screen and wants 4:3 AR), perhaps it will work, perhaps not: video_mode=1440, 124, 38, 114, 240, 3, 4, 15, 27027 thanks my CRT projector natively sup...

Re: ATARI ST core - how to Boot disk?

What about pushing the rightmost button on the front of the MiST after mounting the disk image? In most cases it resets the given core.

Re: Is RGB/SCART blanking signal (Pin 16) too low on some Cores? <1v

Press F12 again! This core has it's own menu structure (just like the PCE and the earlier Genesis cores), accessible with a second 'menu' pushing.

Re: ATART ST - How to get RGB/SCART

Or you may switch on the fly between 31kHz and 15kHz modes pushing and holding the middle (menu) button on the MiST. It worths to check the settings in menu, sometimes the core strucks in non-RGB standard B&W mode. There's an option for PAL mode switching between 50<->56Hz, the 50 is RGB compati...

If no, you may still solder/purchase a 'minimig VGA to SCART cable', it works in most cases. About aspe...

Hi!

I tried it with my BenQ BL912, and both RGB and YUV works, although the colours have a bit different shades, see screenshots (same as on NES core).

Thanks for your work adding new feature to this otherwise abandoned core! :cheers:
