Hi
Im new to this forum. I have a target secured with DS1991L ibutton placed in lpt dongle. I was wondering what are the chances to clone/copy/emulate this. Ive searched nearly everywhere but its not easy as most of it is spam from some chinesse seller offering an copier for 1200usd.
Thanks.

What is the soft name? There were few iButton projects successfully resolved.

The point is to emulate ibutton used in an arcade machine i just bought from local amusements. Machine was made by game werehouse. There is 3 diferent types of dongles they are using. Black one - DS1996, Red and blue (both ds1991). The ds1996 is not that big of a problem as from what i gathered its just 64kb of data without encryption. the 1991 seems to have 3 banks of memory each encrypted with own password. Ibuttons are connected to pc via lpt dongle (ds1410e). Any help will be appreciated.

If software uses encryption you need reverse its modules and understand how the buttons operated. Then just buy now iButtons and initialize as you need. Other way - fix software modules.
