How to get the analog outputs on this thing? Is there a solution i can buy?
There are plenty of HDMI-to-whatever adapters on Amazon and eBay; just pick one with the outputs you desire. Do be mindful that these devices are unidirectional; if you pick up a whatever-to-HDMI converter by mistake, it won’t do what you need it to do.
Do you have any idea how i get nes and c64 into the ossc if composite is not a option (i thought i can plug it into the component like so often).
You will need something like the RetroTINK 2X (does not do PAL60) or VGP’s upcoming Koryuu converter. The RT2X will convert SD/15kHz-only composite, S-Video, and YPbPr component to HDMI, whereas the Koryuu will convert composite and S-Video to YPbPr component.
