If you want a nice one for hacking and that is cheap you could get a blaze retrocon. Go to www.superufo.com and look under the "Cool Stuff" section to order one. This website is the official supplier of blaze retrocon systems, so they have the lowest price. I will be hacking mine as soon as it arrives, so I can make a pinout too. has a 72 pin connector already on it, and it is both pal and ntsc compatible (if you are worried about that- don't know for sure) I payed about $30 for mine with shipping.
Emulation isn't accurate. There is no substitute for real hardware!
The yobo is teeny. Don't worry about the size of the PCB, rest asured that unless you are building a ben heckendorn style NES micro you will not need it to get much (any?) smaller.
