How does the aspect ratio look when running the 240p Test Suite?
I haven’t tried the 240p Test Suite—I’ll need to get that set up. Either way, the aspect ratio is definitely narrower than 4:3.
Does the Dreamcast use 480i/576i for the boot splash and then switch to 480p, or is it 480p the whole time?
I’m not actually sure. I think it’s 480p the entire time. How would I confirm?
Side note: You may want to consider picking up a SCART cable to connect the Toro to the OSSC; the Dreamcast can benefit from the low-pass filtering that is available on AV1 (also AV2) that isn’t present on AV3.
I tried this, but was not able to get a 480p signal, only 480i. I tried every combination of VGA/RBG and RGBHV/RGBS on the Toro, but the TV only accepted the signal when it was 480i, and it seemed like a very low-quality, shimmery 480i at that.
