I got them so they're all ready to play and output to hdmi
- The Saturn and Master System are connected via rgb scart cables to an open source scan converter
- Genesis games are being handled by the Analogue SG which has native hdmi until I can make the repairs to my Sega CD and find the cables for that and my Genesis
- The Dreamcast has a vga box called the Akura that actually outputs to hdmi instead of vga
for obvious reasons it's not going to look as good in the picture but in person it's clear and vibrant :)
