How to link 2 pcs

[mrwhite1970]

Hi all and hello 

I have bought 2 sega rally machines, both running sega rally 3 through tecknoparrot ui 

How can I get them to link play so they race against each other there is an earthnet cable running from 1 machine to the other with a white tp link box

But can't find anything in the menus to enable it?

Both games are installed on both pcs.

 

Any info gratefully appreciated 

Matt
