Running my DOS machine through an OSSC into a E2S does some odd things depending on the game, mostly on the OSSC end. Epic Pinball Pack 1 on Android, for instance, will shift more blue as the screen goes up and the sector flashing in Duke 3D bleeds over into UI elements when it doesn't in the game unless you enable the 2x scale. Now that I've figured out how to muscle OBS into doing what I need, I don't need the OSSC in the equation anymore but still found it odd. Would also try to call 1024x768 as 808p and I'm pretty sure it added extra pixels off to the right of the image.
Going to be using it over the DVI2PCIe I have despite it having a sharper/clearer image (imo) if only because the E2S has 2 inputs which means I can have my DOS/98/XP machines coming in via VGA to one input and the PPC Macs I have running via DVI-D to another and the difference isn't that bad considering how much less I have to hit the E2S into working how I want via OBS. OSSC is gonna make my dreamcast look better on my TV
