Reply To: Default 800×600 handling not being upscaled

I’m trying to connect a DOL-101 Gamecube

Ah sorry, I missed that you have the GC without digital port.

In any case, I think that VGA box is not a really ideal product to pair with OSSC. Even if Marqs were to implement a detection specifically for 800×600, I’m not optimistic the linedoubling (outputting 1600×1200) would look particularly good, because the initial conversion in that VGA box is simply not very kind to the original signal.

I recommend you look for other options, even though they will be neither simple or cheap, e.g. either Retrotink2X, internal GCVideo mod, or buy another DOL-001 GCN and the upcoming component cables.
