Have you ever played D2 and thought the battle mode was just begging for light gun support?
This is a proof of concept patch for D2 disc 1 (NTSC-U) that adds light gun support to D2's battle mode. Expect bugs. It will probably crash on you if you play far enough but it seems stable in the opening area. Ultimately this is meant to be a fun "what if" experiment, not a polished final mod. Enjoy!
Features:
I've only tested with the official JP gun so far. HKT-7800.

Features:
- Functioning light gun in battle mode
- Shoots where you aim!
- When a light gun is present, the aim cursor/reticle only appears when firing and disappears after a short timeout.
- Light gun buttons function during battle mode (only battle mode)
- Gun B = Pad X (shift left)
- Gun Start = Pad B (shift right)
- Gun Trigger = Pad A (fire)
- Gun D-Pad up = Pad L
- Gun D-Pad down = Pad R
- Gun D-Pad left = Pad D-Pad left
- Gun D-Pad right = Pad D-Pad right
- Gun B + Start = Pad Y (reload)
- Hot plugging gun should be OK
- Screen white flashing (necessary for light gun position acquisition) synced to the muzzle flash of the gun being fired - less distracting and looks more natural.
