Hi,

It's in /usr/local/share/attract/layouts/Basic

You may copy the folder to your home dir in ~/shared/frontends/attract/layouts and modify it there

Yeah based on the reply in the groovyMAME forum and just from messing around with it more, I don't think it is a resolution thing.  I think it is more of a 4:3 screen thing whereas the analog control is really just in a 1:1 aspect ratio, so I think there is some sort of translation MAME is doing with that to translate the 1:1 of the controller to the 4:3 aspect ratio of the screen.

Again, this is all theory and I can't prove any of this, but just the way the offsets grows more and more as I get closer to the edge of the screen, that is what I am thinking is going on.

And it's definitely JUST a MAME issue at this point because VCop works flawlessly.  HOTD seems to work too but it is at a slight offset everywhere I aim.  I think it's an in game calibration issue though.  I haven't messed with the in game calibration because I can't read the menus in 320x240 so I have to figure out where to go to calibrate first. 

I should try and get Friction running and see how that tracks.  From what I remember, it tracked flawlessly as well when I did it on my old PC as a proof of concept.

Hi,

Where is the GroovyArcade frontend attract mode basic (layout)  directory?
I would like to change the colors.

Thanks

Haha!  That's the first thing I checked when I went to look at it.  Reached around back and felt the top edge.  Seems he went with black paint.  The machine has held up remarkably well.  Still pristine.  Very sturdy build.  Must have been well loved and cared for by the previous owners.

When I saw the ad on Marketplace, I was not sure if this was a custom machine or a mass produced unit.  For some time I searched and did not find anything that looked exactly like it.  I decided to take a chance and told the seller I would take it.  One last search in the morning before I headed out to buy it and I found this thread.  Very happy to have come across this gem. 

Now to update the insides.  I have a rpi5 ready to set up.
The machine has a GP-wiz40 board in it.  That's new to me as I am new to this hobby.  Will have to do some research.

Custom arcade projects often require precise processing units. The MCF5282CVM66 is a powerful MCU with built-in peripherals ideal for handling input/output operations, making it a great choice for arcade hardware implementations.

I ran VMM again for my CRT and that resolved the issue. 

I had this setup accurate to within a few pixels in MAME, so it definitely is possible.
However, I’ve taken the Emulator PC out of the cab now as my Americas Army Arcade is up for sale as a dedicated cab, so I can’t check through the settings.
I don’t remember having to mess with too many of the settings other than what was in the original thread that you’ve tried. I still link it might be a resolution issue.
Have you tried setting your desktop to 360x240, calibrating the guns at this res and then checking the accuracy in the mame game which is running at this resolution?

Yeah I am kind of at a loss at this point.  I'm not sure what is going on.  I have tried different settings in the MAME.ini file and nothing.  I'm even starting to wonder how accurate it was in my other MAME cabinet when I was proof of concepting this.  I did have the crosshairs on when I was just seeing if it worked so perhaps it wasn't as accurate as I thought it was but I thought it was accurate because I could aim easier with the crosshairs on. 

It almost makes me think that because the screen is 4:3 and the joystick controller emulates a "4:4" in that it is just a circle, that it could be the reason this is happening. 

Like my monitor is 25".

Let's say it is 15" tall and 20" wide.

So to the top it is 7.5" off center.  But to the sides it is 10" off center.

It is almost as if when I'm aiming 7.5" off center horizontally that the tracking is showing it is at the edge at 10" off.  It just seems like it is kind of scaling the movement in that sense.

But then it baffles me how accurate Virtua Cop is especially when I'm hitting stuff right at the edge of the screen.  But perhaps that is because I'm running DemulShooter with Virtua Cop and maybe that is doing some trickery behind the scenes with translation of where the gun is tracking when the trigger is pressed.

For now though, I am completely stumped.

Anyone else who has USB2GUN with Happ Guns, is it like dead accurate with MAME? 

Okay so now I am even more confused with what is going on...

I was messing around with MAME.ini and I got a clean groovyMAME one and compared them and made a couple changes, and still nothing.

I did try setting the deadzone value up higher, and set it to 0.5, and I definitely noticed a difference with tracking in the center of the screen, so I know it's reading that value from MAME.ini.

Then under the CORE INPUT AUTOMATIC ENABLE OPTIONS section I had both the lightgun_device and positional_device set to "joystick" which the USB2GUN is recognized as.

So I removed it from positional_device and no changes.

Then for shits and giggles I decided to remove it from lightgun_device as well, so that I had no devices set to "joystick", and loaded up MAME.

And to my surprised, I am STILL getting the same exact behavior.  It's still recognizing the happ gun for tracking even though I do not have joystick set anywhere in MAME.ini which is completely baffling to me.  I also checked it inside MAME itself and nothing was set to joystick either. 

I did notice that mouse_device was set to "mouse" still so I wonder if for some reason, MAME (or maybe the PC) is seeing the Happ guns also as a mouse input device?

I am going to see if I can play around with this more later on too, but if anyone has any ideas, I'm all ears.

Did he fix that exposed back edge?
