correct. the only advantage is that the controllers can also be used with the wii and wii-u

the analogue nt mini isn't that great in my opinion. only $50 cheaper than the original? what set the analogue nt apart was that it was an actual board set with the same [salvaged] chips from famicom's. the mini just has an FPGA in it (which I believe is probably what the retrousb has. and it's weird that nowhere in the email announcement for the mini do they actually mention that the case is milled from a block of aluminium like the original was

additionally, the retrousb unit is 720p which is a factor 3x the resolution of the famicom/nes. 1080p is not an even multiplier so the image is going to be slightly dithered

I'm not sure, but in my opinion, I can't see how they justify that hefty price tag for the "mini" when it's basically just an emulation box like that others out there.

for me, (even though I couldn't see spending the $500 on the original), the cool part was that you were getting a "real" famicom/nes. they even restricted the number of units that they produced because they salvaged and included the audio chip set from the famicom disc unit. famicom disc titles like the original "legend of zelda" had a much fuller soundtrack, than their cartridge counterparts

"emulation", "simulation"... call it what you like. if the hardware isn't the same, then it's just like a pc/raspsberry pi running an application

I haven't read too much about the mini, but I do recall seeing them post that the reason why the original was limited to [x] units was due to the fact that they only had access to [x] famicom disk systems to vulture the parts from. that circuit board was basically a re-working of nintendo's.

and while it's true that they may have had another year to gather up more FDSs from the 2nd hand stores in japan, unless they've managed to source more than 100-200 at rock bottom prices. plus, if the mini is just an FPGA, did they program it to use the actual audio chipset from the FDS and is it included on this new board? answers to these questions and more are things I do not possess the information
