The thing is, the timing needs to be adjusted or you get audio and visual drops. I think you are right but once I used FBX’s method the OSSC behaved in a new way. Before I would just run the audio from my GSSCARTSW to some speakers but now with SNES the timing is fixed and I no longer get any audio drops. No flickering pixels or any nonsense. I’ve never seen the SNES look better on any HD display using any method.
I used that 320/256 approach for a while with the framemeister. I don’t own a lot of Genesis 320x games so I would try to make a mental note to switch it over. With the Framemeister I had 20 profiles so it wasn’t a big deal to have 3 genesis specific ones (320/256 for 1080p and 1 for 720p)
The thing is, there is timing issues that I think need to be dialed in, in the advanced menus because on my tv 480p x2 and 480i x4 will often desync. The last adjustment he did with the checkerboard is probably the only adjustment necessary to keep your tv and your ossc in sync.
If you are using a 4K TV you can take advantage of some of the TV’s pixel and width features to correct for aspect ratio going wonky. I think you are right in that probably should use the output res instead of the internal if your tv isn’t as full featured in that department.
Default the V. Active even when putting in 480 content is 240. Shouldn’t you adjust that to 480?
FBX really opened up the OSSC to me this weekend and now I want to master it. The world after CRTs is going to happen and if I could get something to look “good enough” on a fixed pixel display I will. As of right now, I can honestly say that the settings for my snes on my 4K are so good that I don’t feel like I need to play it on a CRT anymore. This is probably my first time ever thinking that.
