Well that didn't work but thanks for link.
I managed to get it going a bit.
I bought a usb to gameport adapter(sitecom) and hooked it to my homebrewed adapter and behold it works ..a bit.
I had to do a lot off fiddling in poseidon to get all directions going.
I had to fill in all the numbers off the x and y directions when pushed.
Workes but these numbers are not absolute they are variable.
So when it is not this exact number(if you push not straight) it won't react..annoying.
Is there some way to set this up in poseidon??
Many things you can set up ther in HID.class action.
