I recently had my Dreamcast VA0 installed with Pixel FX's DCDigital HW2. I'm done with my testing and have lost my composite and s-video signal (via AV out). Analog sound still works as I can hear boot up screen and other sound effects related to setting date, time, etc. However, it's a curious and cryptic case that RGB via SCART works fine. Has anyone encountered the same or similar issues?
There is function to switch resolutions from 480p up to 1440p. Let's hope the developer restores in a future firmware update the downscale function to 240p as this was featured in the previous mod chip. I ask this since HDMI to component converters would greatly benefit from this ability.
Finally, there's also video mode settings which allow cable detect but does not seem to have any apparent effect on my unit.
