For those that didnt RTFA, there is a reason for the high price point of this console.
They are not using emulation like the Retron consoles. This isn't the usual Famiclone either. They sourced actual 30 year old Famicom CPU and Video chips to build this custom unit, then hacked the video chip to connect to a custom HDMI output chip so there is no digital-analog-digital conversion process at all. This is straight digital video right from the original NES video chip right to an HDMI chip without any converters. *THIS* is impressive, to say the least.
If nothing else, this entire unit is actually quite the impressive custom hack of 30 year old hardware.
