Are there any trackball/mouse hacks for the 7800 besides centipede?​ I know at least nine were done for the 2600.

If I had a genie, I could just poof my 7800 to PS adapter into existance. I wrote one mode, where you can have the following config:

 

PS-Mouse

------------

P1.SXXX (4bit signed value for horizontal delta)

P1.Button (left mouse button)

P2.SXXX (4bit signed value for vertical delta)

P2.Button (right mouse button)

 

It would be dead easy, to hack any game to use this mouse config, as there is no fiddly timing involved, real time delta's are received by simply reading both joystick ports.
