Libretro gamepad D-Pad only responds to Left presses about dosbox-svn HOT 4 OPEN

That's how DOS gamepads work. Every PC/gamepad/joystick combination would result in completely different port input values. So games always offered a calibration option either in their in-game menus, or in their installers. So if a game has an install.exe or setup.exe, you might need to run that to see if it has a calibration option.

There is nothing dosbox itself can do about it.

I'm open to my memory just being fallible, but I'm old enough to have used DOS machines and I'm pretty sure I remember most games working without calibration. Going through a couple of my games with gamepad support, I can see that Apogee's Hocus Pocus--which I played with a gamepad as a kid--has no gamepad calibration screen, so I'm not sure how this game would have ever worked historically if calibration was necessary.

Wacky Wheels does have a calibration screen, but calibrating my "gamepad" (i.e. whatever the Libretro gamepad is mapped as) doesn't seem to fix anything. I definitely feel like there's something other than "DOS gamepad support is weird" going on here.

I'll try the mainline, non-Libretro DOSBox at the nearest opportunity to see how things work over there.

EDIT: Mixed results on mainline DOSBox (tested on a Raspberry Pi). Hocus Pocus works out of the box, no calibration required. Wacky Wheels, however, has constant down/right input in-game, even after calibration. Oddly enough, this bad input isn't visible in SETUP.EXE, where the calibration is performed and where you can run a pad test. It works great there, just broken in-game.

EDIT 2: Just to note, this was a brand new DOSBox installation, I've never used it before on my Pi, so there are no prior configurations involved here.

EDIT 3: Over on the Pi I was able to get rid of that spurious input in Wacky Wheels by setting the joystick to timed = false.

The cycles setting also affects this. Just like on real hardware; if you depressed the "turbo" button on a PC to lower the speed of the CPU, you'd need to calibrate again. So it might be that games that don't have a calibration option end up being CPU speed-sensitive. On CPUs that are too fast or too slow, input doesn't work correctly.

Anyway, I'll try and take a look at these games myself.

There have been a couple changes and fixes to input handling. Does this happen to change anything in this case?
