Hello. Just wanted to let you know that we are selling a Famicom dumping hardware now in our Ebay shop. Software is of course included but it cannot handle all the mappers for this moment, but that's not important because there are plenty of other software to use the raw files with. So if you got some rare things you wanna backup, then I suggest that you visit our webshop:

Take care and happy halloween! 8)
