   * Atari wireless CX78+ Gamepad Controller. It also has an USB dongle for use on PC. - The mini joystick on the D-pad can be removed

+  * A Sega Master System controller (two button)
+    * It will work on the C64 and is safe to use. The second button will ground one of the paddle inputs, which does not cause harm as it’s designed to read a voltage input (ground=0V)
   * **Not yet available** but in the works; Protopad from Protovision

+Pin 7 on the Megadrive is the ground, while Pin 7 on the C64 is +5V. So pressing the controller pad would connect 5V to places where it shouldn’t be. There are electronics inside the controller to multiplex the buttons and it is possible that would be damaged too.

 ===== USB-stick =====
-Obviously you can just plug any USB mass storage device in the usb port. Like the included usb-stick (cassette). Some usb-sticks have a build in light, that you may or may not wish to have it. Especially if you plug it in the internal usb-A port and you have translucent case.

-It would make sense to buy for this purpose a mini usb-A stick. That looks like one of those dongles for a wireless mouse.
