It should do but it’s not optimal, you’re much better off using a SNES RGB SCART cable. SNES outputs RGB natively, except for the SNES Mini which needs a mod (and doesn’t work with the HD Retrovision cable either).
I got my SNES Mini modded by VideoGamePerfection (great job on it too), but you’re saying it won’t work with the HD Retrovision component cable? Or that it won’t work with it unless modded for CSYNC (like mine already has)?
Can you (or anyone recommend) top quality cables for Sega Genesis and SNES therefore to use in conjunction with the OSSC? I’ve bought both Genesis/SNES cables from RetroGamingCables so far, but considering the Genesis issues I have I’m looking for “the best” cables to use. My SNES cable from RetroGamingCables displays some artifacts with the OSSC too (minor, but noticeable).
