Steam Deck Terminator 2 Sinden Light Gun

Batman4Life

Hi All. I’m experiencing light gun drift on Terminator 2 with the latest dev build for Steam Deck. When I move suddenly a different direction, the onscreen crosshairs can drift wildly, making it unplayable. Any suggestions?

I’m on the latest Sinden light gun firmware (1.8). I’m also running T2 with MAME 2010 option as it was the only one that worked.

Current version of Botecera: 36-dev-db3b95866a

I have Duck Hunt and Hogan’s Alley on NES working fine, if that helps.

Light gun support is broken in mame2010, but it should be working OK in v36 (the core was updated for light gun support from some devs). I believe that in Input of Core options there is an option that you can change from mouse to lightgun but I’m unsure. This game is an adstick shooting game, not a true light gun.

Suggestion : use either mame2003plus or MAME standalone for now with the correct ROMset (reference set mame 2003 plus or MAME 0.245).

Thanks so much. I tried mame2003plus but still had the same experience. I wonder if that’s just how the game plays. As long as I don’t move too fast, it does track but never accurately like the other light gun games (Virtua Cop 2, Duck Hunt, Hogan’s Alley, Area 51 on Saturn). It reminds me more like a gamepad moving the cursor but with momentum.

In mame2003plus, open up RA menu (hotkey+south button of your controller), go to Core options ->Input -> switch mouse to lightgun. I will try tomorrow on my PC to verify it’s working correctly (I have both 0.78+ and 0.245 ROMs) and get back at you.

That was it! Wow, thank you. I’m sure that was basic but it tracks and everything is fixed.
