Aimtrak gun loses alignment when I aim off the screen. <tag> Aimtrak <Tag>

@quicksilver For the Tilt/Z corrections I have it set to None, I believe I tried all three early on but will check each again. My off screen calibration is set for my right side button which I don't use in the games I've tested.

@dureq83 Have you tried contacting Ultimarc directly? They may be able to give some troubleshooting advice. My apologies if you already said earlier, I havent read through the entire thread.

dureq83

Yes, I contacted Andy with Ultimarc and he didn't know what might be causing the problem.

I just unbound everything for player 1 up, down, etc, and light gun player 1 up, down, etc... and the light gun is still working, although still having the drifting problem. So if the keys are unbound then why is the light gun still working?

dureq83

I found something promising! I just launched Lethal Enforcers 2, unbound all the keys and found that the lightgun was still working. I then hit Tab in the game and brought up the game menu. I went into analog controls and turned the lightgun sensitivity down from 50% to 25% and now it's no longer drifting!! I'm going to find a good setting % and see if it fixes the problem!!!!!!!

dureq83

Great news! The issue lied in the Analog Controls portion of the in-game menu. I still don't know how the lightgun is working when I purposely unbound the light gun Y and X axis for -/+. I turned down the lightgun sensitivity and it corrected the issue.

Now, I would like to thank everyone who added their input and helped me get to this resolution. Big thanks to Efrllm for sticking it out with me for over 60 posts!

/opt/retropie/emulators/advmame/bin/advm this is a executable file, you call it directly and it will read controller events.
I was stuck trying to understand what js/mouse event it wanted to use.

That is great news, there were a lot of settings there, I would not have thought of this solution.
You're welcome, I'm glad you didn't give up on it.

https://github.com/gunpadawan/gunconf setup util for linux you can set it as a mouse or joystick

Hi dureq,

Out of interest what setting did you find works well?

Did you settle on 25%?

dureq83

25% seemed to work best for my size screen.

@dureq83

Great, thanks.

What size screen do you have? It might then help me to pick a starting point

dureq83

32" LG 720p

I read somewhere that a candle shouldn't be used in place of the sensor bar. Do you think the sensitivity was part of the ambient light in the room?

It looked a lot like the cursor dragging, but thinking about it now, the sensor was probably just identifying to the wrong light sources when it was taken off screen.

Then again the analog setting was a solution so maybe it was drifting while it reached a determined maximum value.

i have a wi mote that easy enough to map up in linux. Ill just need to get a sensor bar ill knock something when i get one. Ill make a bin for testing when i get round to it for people with aimtracks wiimotes doplhin bars ect.

@grant2258
How do you map a wiimote? I have a motionPlus controller so maybe it is just difficult.

If I sync it, it will show up and the buttons are there in jstest, but when I use it is identified as a keyboard in emulationstation and only the directional buttons work.

grant2258

really depends how you configure it and what you want to use it for in my case im only interested in two buttons and the ir sensor

Wiimote.A               = BTN_A
Wiimote.B               = BTN_B
Wiimote.Dpad.X          = ABS_HAT0X
Wiimote.Dpad.Y          = ABS_HAT0Y
Wiimote.Minus   = BTN_SELECT
Wiimote.Plus    = BTN_START
Wiimote.Home    = BTN_MODE
Wiimote.1               = BTN_X
Wiimote.2               = BTN_Y

should get you going not tested it obviously you can change the mapping any way you like

for ir sensor add

Plugin.ir_ptr.X = ABS_X
Plugin.ir_ptr.Y = ABS_Y

I know the ir sensor is working fine i tested it with my remote control just need to get a sensor bar if i ever get round to it

grant2258

Well ive added light gun support to my wee mame 095 test core its not an official core very much beta for my personal use. when i get a sensor bar ill test it and let mark know if it works or not then he can decide if 2003 and plus will get light gun support if it does.

grant2258

ok used two ir leds soldered to a usb cable to test the wii more doesnt work well unless you stand in the exact right place every time you defo need the cross hairs on. I dont see how the aimtrack will be much different unless the user uses the gun in the exact same position or calibrates it when the distance/height/player changes. Even changing people with different height would knock this out. Anyone with a aimtrack had much success without cross hairs on?

@grant2258 I think that’s the issue @MrLightgun invented his light gun to solve. But if you have code changes that will make a lightgun of any kind work with lr-Mame2003-plus that would be awesome. I could never get it working right with my dolphin bar/wiimote setup, and in general libretro is way easier to use than advancemame for most people including me.

grant2258

well i dont have a dophin bar ill mess about with the MoltenGamepad looks promising since its using the kernel drivers for the wii mote not the easiest to setup for users though. Ill do some setup tests with this and see if something is doable for the wii mote.
