Aimtrak Light gun and Mame2003

@HurricaneFan What I really wanna do is figure out how to use this setup on consoles like SMS/NES/Genesis. There are a few crappy emulators (DGEN, Osmose) that it half works on. I can fire, but crosshairs wont move.

HurricaneFan

@BGallagherLA I think the issue with other emulators is it reads the mouse movement differently. I thought I saw something that the emulators need to be able to use absolute positioning and a lot of them use relative positioning.

@HurricaneFan yes it does, which is useful to make sure the gun can see the IR led and also reconfigure between games (mouse or joystick for instance)

@HurricaneFan said in Aimtrak Light gun and Mame2003:

So the number 5 on my keyboard inserted a coin, and number 1 started the game. The dolphin bar recognizes the wiimote in mode 2 and you get a crosshairs that shows you what your pointing at. The trigger button shoots.

First test results are not really great (using wiiremote plus & mode 2, tried both advmame 3.x and 1.4):

will act as mouse only if really near (1m) to the sensorbar
pointing area limited at the bottom (regardless of top o bottom setting of the switch on the bar); can't aim at the lower part.

Any suggestions ?

HurricaneFan

@UDb23 I use my wiimote about 3 1/2 to 4 feet from my sensor bar. I don't think I've seen an issue with pointing at the bottom. What game did you test?

@HurricaneFan forgot to tell: operation wolf

Tried again and now it works great. Bar was positioned incorrectly I think.

@HurricaneFan Do you know if it would work also as steering wheel for driving games?
Dolphinbar manual mentions this function but no idea on how to activate it with advmame.

Dolphinbar manual mentions this function

I actually contacted the manufacturer about that claim and they said it was a feature that could only be used in Dolphin. However, it pretty clearly says in both the manual and website that it should be available as an alternative control method for for the USB HID controller mode. I also asked around on the Dolphin emu forums, as the device is widespread there, but no one knew anything about it. It would be great to use it as a steering wheel, or for other analog control schemes. The implementation of Stella on my hacked Wii makes use of the same idea for nuanced paddle control and it works extremely well.

@mediamogul I know that there is a steering wheel mount thing that you can put a Wiimote in, but I dont think that comes with pedals. Even if the steering wheel does work, you'd probably have to get a separate thing for the pedals, and i'm assuming that would be a nightmare to set up/configure. Would be super cool though...

@BGallagherLA

I have a few of the official Wii Wheels. They're a surprising amount of fun.

BGallagherLA

@mediamogul Have you gotten them to work on RetroPie? Do you need pedals, or can you just map the Wiimote buttons as gas/brake?

@BGallagherLA

I haven't tried it myself, although I'm pretty sure it won't work in conjunction with the DolphinBar unless that advertised sensor mode is somehow alluding us. However, if any of the linux Wiimote drivers pass the g-sensor information along as an analog controller axis, then it should work just fine.

@gunpadawan I'm getting this error when I try to install the setup.py script step:

pi@retropie:~/gunconf $ python setup.py install
Traceback (most recent call last):

@HurricaneFan sounds like you are missing setuptools
try this:
sudo apt install python-setuptools

@gunpadawan Now it's throwing this error:

pi@retropie:~/gunconf $ python setup.py install
running install
