Checking on this the HDMI can be converted to HD-SDI which is a digital signal. The BVM internal DAC’s are reported to be better than what game systems came with. However I’m not sure if it is worth the cost /effort.

It’s just that I have one, so in this case I wouldn’t have to drop ??? $$ to get a different retro system and a game. It also plays PS1 games so that opens things up a bit.
