Kevtris,
Admittedly I haven't read all 44 pages of backlog but I read quite a few. There's a market segment you may not have considered for some of the analog outputs. The arcade hobbyist could have a field day if there were a way to slap a jamma harness and/or jvs interface on there. In fact you already offer a pc10 palette option in your nes core. I could imagine this helping preserve pc10, nss, and even neogeo. It would be a neat idea to simulate a pc10 with some other unofficial games too.
Just a thought / consideration for further marketing of your dream box. Keep up the fantastic work. Im saving up for an nt mini and can't wait to experience it!
