&gt; <i>A NES with composite compared to the AVS is a stunning difference in picture quality.</i><p>So one counter-intuitive complaint of many modern emulation systems is that they provide &quot;pixel-perfect&quot; rendering. I.e. what the console outputs is what you get on screen.<p>Except that&#x27;s not how the games looked back then! The video artifacts of TVs at the time, composite signal and NTSC, meant you had color bleed and slightly blurry pixels that weren&#x27;t even square. It&#x27;s not just scanlines. For practical examples, see this Gamasutra article [1]. Most telling to me is the comparisons of Link (from Zelda 2) therein.<p>The AVS page doesn&#x27;t mention any of this, so am I to deduce it forgoes emulating these artifacts?<p>[1] <a href="http:&#x2F;&#x2F;www.gamasutra.com&#x2F;blogs&#x2F;KylePittman&#x2F;20150420&#x2F;241442&#x2F;CRT_Simulation_in_Super_Win_the_Game.php" rel="nofollow">http:&#x2F;&#x2F;www.gamasutra.com&#x2F;blogs&#x2F;KylePittman&#x2F;20150420&#x2F;241442&#x2F;C...</a>

It&#x27;s &quot;Famicom,&quot; not some kind of organized convention!<p>It&#x27;s short for <i>Fami</i>ly <i>Com</i>puter.<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Japanese_abbreviated_and_contracted_words" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Japanese_abbreviated_and_contr...</a>

I love these kind of projects. I&#x27;d love it even more if it was open source.<p>Preservation of the software is the most important thing and I&#x27;m glad the game pirates are very fastidious about it, but preservation of hardware like this is - if not as important - at least as fascinating!<p>And still, I won&#x27;t buy one. I doubt I&#x27;ll ever earn enough money to make retro game collecting feasible, so I&#x27;ll stick with collection retro game controllers and connecting them to PCs for faithful emulation ;)

Interesting project - I wonder if this uses the 6502 core from Visual6502.<p>The price point might be tough for people. I think you can buy original NES systems for less. They aren&#x27;t going to be HDMI compatible, but I think those adapters will run you $20 on Amazon.

Maybe it&#x27;s my knackered, 50-year old eyes, but the white writing on blue background is not nice to read.
