Interesting discovery I made with DoDonPachi DaiOuJou and Espgaluda on the ps2 yesterday evening -
In regular hori mode, they both have that dreaded PS2 480i interlaced video signal, no scanlines and the image flickers. Actually made me a little nauseous yesterday.
If you flip them to tate and play them vertically they both magically change to 240p! So lovely thick scanlines and no flicker, looks absolutely stunning like a super bright arcade monitor.
I actually have an Extron RGB which downscales all 480i content to 240p, so you can do that with all consoles that lock to 480i. Going to see if I can find some way of working it into the setup.
