I really don't want to drag my old CRT back in the house , also all my capture cards are for hdmi, are runs on the Retrousb avs fine for submission? and if so would you be submitting "nes" if playing og cart and "emu" for everdrive subs?

The answer to this is going to differ by community, since each game community sets its own rules. That said, this console uses FPGA, which is a good sign.
