The dongle was first used to protect software, kind of a built in security system in a small device that looks similar to a USB storage device. Dongles now have become popular as adapters for wireless connections as they have embedded in them a software to verify the user (or the users rights to access the program or system). Gaming systems are now using them but the biggest problems
. manufacturers are facing now is cloning and drivers. The programs and codes built into the programs are often easy to "break" so now you can find the emulator downloads all over the internet for free. You can find more information here: http://wareseeker.com/free-dongle-emulator/
