custom image needed. will pay.

@caver01 speakers are connected to the 1/8" audio out jack on the pi. That's it isn't it. I need to tell the pi to use that jack and not the hdmi....

@outahere91 might be, yeah. I guess it is supposed to auto-detect, but most folks specify with raspi-config. That's what I do. You may also need to add disable_audio_dither=1 to config.txt to eliminate hiss during silence.

You could also setup USB audio which will sound better.

Thank you to everyone for your help.
I've gotten it all working so far. It seems to emulate better with advmame, and I managed to get the trakball set up and working.
question for @caver01 and others emlating golden tee in advmame?... what settings do you use for your trakball. I was going to play with this today. I'd like to match the arcade game feel as close as possible. I am going to use the U-Trak from ulitmarc connected through an ipac2.

@outahere91 Still need that image or are you good to go?

@outahere91 Are you talking about sensitivity settings? I have the utrak and I don't think I changed them for any of the GT series, so I am basically using my trackball as-is. However, I also have spinners and joysticks, so I probably mapped some of the functions of these, and I definitely removed control of the swing from the joystick which often doubles analog by default--I guess the thinking is that users might not have a trackball.

@caver01 the default sensitivity settings didn't work too well for me. I could barely move the golf ball. I increased the X & Y sensitivities from 25% to 70% and it works much better. I want to do my best to match the original game, so I was wondering if others had it dialed in.

@outahere91 I will check my setup again, as I think it is working fine. I do run the utrak through its optional dedicated USB interface, which may or may not make a difference.

@outahere91 I am using a sensitivity of 25% and a digital speed of 32. Got a realistic 308 yd drive off the first tee of GT3D, Cactus Canyon, and the other versions of GT have the same feel.

@caver01 thank you. Interesting. I'm going through the ipac2, but I would think the circuit is the same thing. I guess there is some variability.

caver01

@outahere91 might be. I have noticed that you can get interesting results from changing the digital speed as well,as sensitivity. I am still never certain which one I should adjust, but I usually start with sensitivity.

I just realized that I also have a faster poll rate set for my mouse.
--that might make the difference. It basically magnifies the samples per second to reduce digital "backspin". I bet that's why.
