ooh i have a thing called like the computer entertainment system which looks like a nes and plays nes games too as well as uses the same controllers it works great but the slot loading thing is crap so i have to put it on its side for it to work
Depends on what you want to do with it. I'd recommend the AD1, the one without the case. The case looks bulky and pointless. If you want to solder a UK NES adaptor onto a NOAC, get the AD1; just rip off the connector and solder up the pins
I think you are missing the yobo and the retrocon for the console based types. Also, I think you are forgetting that most of the console based Noacs made today are actually just as small on the inside as a super joy III and they tend to have a 72 pin connector installed already. Check out ebay, there are boat loads of them floating around at insanely inflated prices.
Emulation isn't accurate. There is no substitute for real hardware!
