just to clarify, it has side borders?
I’m not sure what you’re getting at, maybe I can test a specific game for you?
also can you (or someone else) test entering a special stage in sonic 2? the bright flash of white causes the XRGB-3 to lose sync to the console. I would like to know if it happens with the ossc or not.
I’ve not tested that bright flash specifically but you can cure that problem on the XRGB3 by using a clean sync (CSYNC) cable. The OSSC is not affected by that issue at all.
As for SNES issues and XRGB, XRGB2/3 are a lot less compatible full stop with modern TVs.
