Emulating Resident Evil Gun Survivor 2 and using Lightgun

[Jayinem]

I've tried on PCSX 2 but there's a delay in the shot like a second and it ruins it. I've also tried to run the Naomi arcade rom on Flycast and it runs really good on it (great emulator btw for Sega stuff) the only problem is the character just flies over to the left or right without you even pressing a button. Has anyone been able to successfully emulate this?

I mostly fixed it when I choose lightgun in settings the character goes crazy and moves when you try to aim to the left or right with your gun but when you choose mouse and map the direction buttons to a gamepad it works as it should. The only issue I have now is the trigger button and button 2 are reversed when I have to shoot with button 2 instead of trigger on my EMS Top Gun 3.
