I wouldn’t have been very good at explaining all of that in detail. 😛
I have to keep any timings that work for me documented because I prefer optimised modes where possible. I know FirebrandX has some videos, but then some consoles can still slightly vary depending on cables etc. I’ve never been 100% sure on what settings to use for PS1 games with all the weird resolutions they have and even my SNES settings are guesswork at the moment.
