RetroScaler2x AV/SV/YPBPR to HDMI™ Converter - Supports Line Doubler, Filter and Pass-Through Modes, Video Game Adapter with No Lag, for PS2/N64/Dreamcast/Saturn/MD/NGC/SFC and More

Well you go 2 options really you can go cheap for a hdmi converter. Main issue with those is that the quality generally sucks most of the time and comes out really blurry. Their are a few good one out there but you have to get lucky to find one. Best one I’ve used is this one it’s damn near close to my retrolink so a good budget option. The other is as I mentioned, get you a good retrolink. Basically does the same thing but you get far crispier outputs and less input delay. Also retro links or pretty universal so you can use the same box with other retro consoles not just Sony models But honestly man I would say away from any of the cheap converters like I said I’ve tried out a few and all of them were really back and laggy. Like I said the one I linked is the only one I’ve ever had good experiences with.
