There are of course other avenues to play old games today: backward compatibility between some systems, download services, emulators, and clone consoles. Each of these methods come with unique drawbacks, some of which may matter to you and some of which may not. While the pros and cons of these options are sometimes discussed here, there's not enough room in this OP to delve into all of that, so if you're the type of person who prefers to use original hardware for the genuine experience when possible and want to know how you might be able to do it better, then read on.
Sync: A potentially bothersome issue with RGB cables, system mods, and processors is how they handle sync. VGA cables carry RGBHV format video: red, green, blue, horizontal sync, and vertical sync. SCART cables carry RGBs: red, green, blue, and sync. SCART sync is often called composite sync (c-sync) because it's a combination of both horizontal and vertical sync. It's important not to confuse the difference between composite video and composite sync. Composite video is the combination of ALL video data (brightness, color, and sync), while composite sync is just sync. What makes this a potential issue is that the designated sync pin on SCART cables can actually carry either of these signals, c-video or c-sync! Many TVs and upscalers can utilize either of these signals for sync without any issues, but others specifically require one or the other.
