That will effectively map a virtual mouse to the left joystick, as well as the left & right mouse buttons to the a & b buttons. Once you map your controller, you would just add these arguments: I've got to head out for the day, but I'll leave you with a guide to get you started and the additional commands to do what you want to do. You can install that from the RetroPie setup menu if you are interested. Some experimentation might find a balance or you can't use both a spinner and joystick in the same build unless it's sampling at a lower There are a couple of ways to do it, but I use xboxdrv. I am not sure how to get around that as the spinner is using raw mouse input. However, this puts more load on the CPU, so care should be taken when adjusting this value. In situations where lag is critical-for example games-some users decrease the interval to as little as possible. If the polling rate is 125 Hz, the mouse position will be updated every 8 milliseconds. The table shows the relation between polling rate Hertz and the corresponding interval milliseconds (rate = 1000 / interval). Thus, an interval setting of 10ms will actually use 8ms, 7ms will use 4ms, etc. However, USB controllers round the interval down to the nearest power of two. The polling interval is measured in milliseconds (ms) and equates to lag time. The polling rate of a device is measured in Hertz (Hz) and is determined by the polling interval. So slowing down the sample rate was throwing off ScummVM as the analog stick works as a mouse. The XBOX 360 controller which is sampling I believe at 1000Hz. In games like Tempest you start back spinning because the resolution rate is so high on the spinner. I set mine to usbhid.mousepoll=2 so I could use a spinner that's sampling at 1200Hz. Try adding this line to /boot/cmdline.txt: ![]() The xbox controller worked fine on the last version but after upgrading not so much. If I use the keyboard with trackpad no issues. I also have the same problem with the lag on my xbox controller. I don't think that has anything to do with it but just trying to figure out the issue as ScummVM is a said in ScummVM lag with joystick control: Maybe that's by design but it would be more intuitive if it remembered how many players you originally configured. If you go back in the settings and look at the number of controllers you enabled it always shows (currently 2). If you set number of controllers to enable = 4, enable the driver and reboot it works fine for 4 players. I did notice in the RetorPie Setup under Setup / Configuration | Option 829 Xbox / Xbox 360 gamepad driver. I'm using 4 wireless XBOX 360 joysticks with the official Microsoft wireless dongle. I am using RetroPie Setup to load the driver with 4 players. I don't know what other relevant information might be helpful in troubleshooting the issue. I have about 36 games installed so I don't think that would be an issue. The same as Bassman it worked with no issues in previous version of ScummVM (RetroPie 3.6). It's pretty annoying as you always distracted by the cursor warping around with a small delay. Yeah for sure it works it just warps around sometimes small jumps and other times large jumps playing catch up. Works ok on my xbox controller analogue stick though when I last tested. Said in ScummVM lag with joystick control:Ĭorrect.
