De Swordfish code komt uit de handleiding. Je kan ook de EasyHID plugin gebruiken, dan moet je wel eea aanpassen, anders werkt het niet samen met de VB2010 code. De EadyHid plugin is ook te gebruiken met Proton.
Visual Basic 2010 kun je gratis downloaden. Zet wel even "mchid.dll" in de map Windows/System32.
