I understand that the mouse can be used to emulate a lightgun positioning device, but I have not been able to get that to work. If that’s the case, could a digital joystick be set to emulate a mouse with another app? That way the joystick could be used to play a shooting game. A game like HOTD2 could be played like Space Gun or Alien 3.
Aimtrak guns are unobtanium right now and so are Sinden guns. Options seem just rather limited.

yeah, analog sticks can often work as mice, too. You can also use a dolphinbar+wiimote in mouse mode.
My ultimate goal is to emulate light gun aiming with digital joystick in the flycast core. However, I think there is an issue with the current flycast core not supporting 2 separate mouse.

After some more work, I have managed to get lightgun aiming working using a joystick. I used joytokey to have the joystick emulate a mouse. I still have not managed to get the aim pointer to show on screen though. Work in progress…

More progess made an an important discovery. The crosshairs don’t work with the vulkan driver. I don’t know specifics between drivers yet, but I know vulkan was needed so mslug6 looked ok. I changed video to gl and crosshairs now appear.
Also, for HOTD2, do not map start and select to the same button as it causes issues. Map select to your start button (for coin up) and and start to your fire button.
The next step is seeing if I can get 2 players going at the same time. Then I’ll save a core remap file(?) for this and other shooting games as needed.
Joytokey needs to be set to run as administrator or it won’t be able to control the mouse. I turned off UAC to get rid of the windows warning nag.
Rob
good luck, and let us know how it goes 
After some more thought on the subject, it’s probably something that’s not possible. Mame does a very good job of managing control input, but unfortunately doesn’t emulate some of these other systems very well yet.
