Hi Tym,
The issue has been identified and it is indeed related to the interlaced resolution. Using progressive mode, you will not encounter freezes. This is a workaround until proper solution is found.
Cheers!
Do you know of a progressive resolution that works well with the Attract Mode frontend? I tried this one that you mentioned in another thread...
modeline "640x240" 13.22 640 672 736 832 240 243 246 265 -hsync -vsync
... but it made the Attract Mode frontend's raster all squeezed into the center of the screen, and made the text practically unreadable. I'm not sure why it did that with the Attract Mode frontend, because when I exited out of it and went into LXDE desktop frontend, its raster wasn't squeezed like that, even though it was definitely using the 640x240p mode.
I'd like to find a progressive 15 KHz resolution that works well with the frontends because interlaced modes look bad in general on a 15 KHz CRT arcade monitor. The games on the other hand look perfect because they are using their original progressive resolutions.
I have an original Capcom Street Fighter II: The World Warrior boardset, and in GroovyArcade, the SFII: TWW ROM's raster looks identical to the raster from the original hardware. I have the monitor adjusted so that the CPS1 games are centered and fill the screen perfectly, so is there any way to find out what modeline would exactly match the resolution that the CPS1 ROMs use when they are running? I'm not sure that even that would work though, considering the results I got with 640x240p which differed drastically depending on which frontend I was using.
