I guess I’m a bit behind the rumors already 
sd2snes will be available soon from KRIKzz. The first stores to sell them are Stone Age Gamer and Retrogate.

I’m asking everyone on the 2012 pre-order list (who got a confirmation) to contact me whether you would like to stay on the list or order from one of the stores. Honestly I really encourage you to do the latter because it gives me more time for actual development. 
good news
tell us when it’s possible to buy it
Very nice!! do you have any estimation about release date? or do you have link to preorder list or something like that?
Thank you in advance!
KRIKzz says he will start shipping in March so I expect shops to take orders around that time. That’s all I know though.
