Analogue joysticks for Amiga

[StompinSteve]

Update: Started Knights of the Sky. Cannot find a calibration feature of any sorts and the plane flies like poop (same problem as GS2000 and F15 II)

I then started A10 Tank Killer v1.5 which has a "calibrate joystick" function in its Preferences menu. Selected Analog Joystick, clicked on Calibrate and jumped into the plane and...

...it flies perfectly. It totally works.

Update: Mig29 Fulcrum, Mig29 Super Fulcrum and Jet Pilot (has a calibration function) work fine too.

(the stick was/is still adjusted with the trim screws so it reads correctly in AnaCal and travel in all directions is the same).
So I guess my Gravis stick is not going to work in games that do not have their own calibration/center stick routine and unfortunately many haven't <insert sad emoji>

Alright, I added 2.2uF caps on the adapter which increased AnaCal peak values to around 220.
Both Gunship 2000 and Knights of the Sky (and every Microprose flight sim) are still using same fixed values (0-44 and around 15-25 null zone).

So no, it definitely isn't hard-coded for a 0-44 range and 22 centre point.

I haven't disassembled these games to check, but I would guess that games without a calibration routine make some assumptions such as the stick being centred when they start, much like modern analogue stick controllers. From that they can take a rough guess at the range of movement - if your stick reads 22 when it starts, 0-44 is a reasonable guess at a range.

Can't figure explanation other than you didn't double check current centre trim value after testing.

There is patch for these games that implements adjustable center point, but it only works with Amiga Smart Port https://aminet.net/package/game/patch/SmartPortUpd

I don't remember if there was any analog joystick for Amiga but as I mentioned in another thread today, long ago I used QuickShot Warrior 5 with pc to amiga adapter
