When the trackball is not recognised i get no response from the cat / dev/input/mice command,and when it is detected i get the usual character output.

Going to try re-imaging the card incase i've messed something up, and have another play later.

Not a bad thing to try, but if this was image corruption it wouldn't be changing. I wonder if maybe the USB connection is intermittent or perhaps draining the power to a point where it stops working. Because the 'test' revealed that when it's not working, linux itself isn't even getting the inputs. I've seen similar issues when plugging in too many devices without a good power supply, or not using a powered USB hub.

Here's a video...

@challenger2010 said in Trackball or spinners in libretro emulators:

Yes, confirmed. There are menu options for it in 2003, but it won't pick up any mouse movement when you try to change it. Hence, no trackball or spinner games will work properly. I would put this on the wish list for 2003 which just might make it the best emulator to use.

:( if you want, you could log an issue here: https://github.com/libretro/mame2003-libretro/issues

i'm not sure if it's an issue with libretro (the api), or mame itself. if it's the former, i think it's more likely to be fixed, but yeah!

Off topic, any chance of getting 2003 updated from Mame 78 to 84? More game support, and is known as the last stable build for Mame.

hmm, that would be tricky i think. perhaps if the source code is available somewhere we could see the differences.
