I've put together an extensive review of the "Joy-16 Mega Drive 3" clone. It is a quite accurate Genesis/MegaDrive clone I purchased for the wonderful sum of 500 yen (~$4.25 at the time) and it came with an official Genesis 6-Pak cart, CIB. What a deal.
The review features disassembly, high-res PCB photos, audio comparisons to a real MD1 system, and a video comparison.
Enjoy.
