Nice! I think that for multiple Scorpion games on the same device, it'd look like the picture below (showing 2 different games with example names, each with their own configs).
For controls remap, select the game in your mini device pressing "A" on the mini's gamepad. Then press the menu button on gamepad, and go to "map gamepad". You may also wish to use "joystick port 2" as CD32 pad because you can use X (green button) to instantly shot the weapons such as knives and axe when you pick them.
