Summary0006648: ReadJoyPort parasite outputs in joystick mode
Descriptionrelated to 0006647

2/3 button joystick mode is completely broken. Take Moktar for instance, character keeps jumping and jumping.

the fix 19.0 => 19.1 is required but not enough.
Steps To Reproducerun Moktar (other games probably "work" too) with WinUAE with "USB Gamepad" in "default" mode (not CD32 joypad)

Character jumps and jumps ...

Working fine with CD32 joypad setting.

The game seems to set potgo=$0f00.
This breaks as WHDLoad does set potgo only during DETECT or when querying cd32pads.

ouch, okay. Very good that it's not a whdload problem then!!

Can you point to the part of the code that does that? (maybe in the Moktar mantis issue?)

Hmm, gameport.device installs a vbi which writes potgo on each interrupt via potgo.resource.
I will change WHDLoad so that it writes potgo each time.

I've tested before and after the fix - can confirm reproduction of continual jumping with earlier beta, and it is now fixed by your POTGO change for me (testing in WinUAE). Nice one. =)
