dosbox: patch to support full mapping of joysticks

[joshuakraemer]

Without this patch, dosbox is only able to use:

• either 2 joysticks/gamepads with 1 analog stick each (no hat switches/d-pads)
• or 1 joystick/gamepad with 1 analog stick and 1 hat switch/d-pad (with joysticktype=fcs)

This patch allows full mapping of 2 joysticks/gamepads with 2 analog sticks and 1 hat switch/d-pad, which means modern joysticks and gamepads can be fully used to play dos games in 2-player mode.

This patch is also used by Recalbox OS, see https://github.com/recalbox/recalbox-buildroot/blob/master/package/dosbox/dosbox-003-joystick-8axis.patch

What is the upstream status of this patch? We usually only patch to make packages work or fix issues, not to enhance functionality.

[joshuakraemer]

I have filed a feature request to reconsider the patch upstream, which was already suggested in 2011: https://sourceforge.net/p/dosbox/feature-requests/137/

@joshuakraemer are you following dosbox-staging? We could package that, instead.

I have a dosbox-staging template but I'm not sure if it would be wanted

IMO we should stay with stable releases and, if absolutely necessary, backport patches. I believe this is the consesus for Void packages in general.

dosbox-staging is a fork

[pullmoll]

Uh, ok, that's a different story.

[joshuakraemer]

Thank you @ericonr and @abenson, I did not know about dosbox-staging. I have already thought about packaging dosbox-ece (template here: joshuakraemer@c926d79), but I think dosbox-staging is the better choice. I would second packaging it.

While it does not solve the original issue (full mapping of controllers), the team seems to be more open to community suggestions, so I will file an issue with them.

Edit: dosbox-staging issue: dosbox-staging/dosbox-staging#342
