DEMULshooter + MAME + strange calibration issues and Terminator 2 crosshairs weirdness

Hi everybody,

I use a Sinden lightgun and have a couple of questions regarding DEMUL and MAME:

1. Can I use DEMULshooter with MAME in any way (most probably not, I assume...)? I'm asking because DEMULshooter solved my aiming and calibration problems with House of the Dead 2 and Sports Shooting USA - now they work fine.
A game like MAME's Police Trainer on the other hand has a very accurate calibration but only in the test menu - as soon as I exit the test menu and start up a game the aiming is way off diagonally...!? (Area 51 and Point Blank work fine.)

2. MAME's Terminator 2 shows a very strange behavior and still gives me a headache: First, all the game did was to just shoot in the upper left corner, it didn't recognize the Sinden at all apparently. In the calibration menu I used the keyboard cursor keys to somehow move the crosshairs around in order to get to the upper left and lower right corner (otherwise I couldn't have calibrated at all), and the left/ right movement worked fine but strangely enough, as soon as I moved the crosshairs up or down it automatically reverted to the middle position like there was a stuck button or something! But no other game shows this behavior. ... Now at least I can play the game but there's always a ghost-like appearance of a second crosshairs in the upper left corner.

Setting this whole lightgun thing up for all games and emulators is really a pain in the a** but at least I've made some progress in the last couple days.

Any help for these two things would be greatly appreciated. Thanks in advance as always!

Hey Alex, I'm in the same boat buddy! I've been setting up MAME games out the box okay with the sinden software but T2 isnt working! when I play the game the cursor goes to the top left and when I try to calibrate its juddering all over the place.

I use the "gunmouse" CFG file and tried creating a term2 ini file (for offscreen reload) but didnt work?? I've also found a 2nd ini file for the games loses my scanline settings which sucks!

If you found a fix I'd really appreciate your advice 

Fingers crossed

This is precisely my problem ATM. Trying to configure my Sinden to play HOTD in Model 2 Emulator, and there's just something wrong with how DemulShooter is handling the gun. Through the Device Preview I can ascertain that the problem isn't with the emulator itself.

Update Believe it or not, I solved it embarrassingly quickly by turning off the anti-jitter feature. 'twas the cause of my troubles all along.
