Hi!
I am running it from the launcher - and that is where I launch the staging version of dosbox too. Only the staging version works for me for some reason. I have uninstalled everything (including the .conf files in appdata) and started afresh but I get back to the same position. I can run it in staging dosbox (from the rendition launcher) but not the normal version. However it is running so I guess I'm not missing out on any functionality?
However - I have tried Ctrl-1 and remapping my controller in dosbox via the mapper about twenty different ways now (and with/without the joystick lines changed in the .conf file as you outlined). In dosbox it sees, recognises and and loads my xbox one controller and lets me remap the bindings after clearing all of them first - but in-game it doesn't recognise any input at all. I've tried 2axis, 4axis, 4axis2, auto, timed true, timed false, swap34 etc etc - but no luck!
It is driving me mad now (pun intended - as the one thing I can't do is drive the game!!)
I tried a second different controller with the same result - I can remap in dosbox no problem - but the game ignores it. No matter what joystick on the controllers I use or what I remap it to in dosbox the game can't pick it up in the calibration screen.
Any further ideas would be amazing!
All the best.
