I would like to know if it is possible that you add the trainer for the games uplay there are some but the problem is that it only offers the version for steam and origin
If the game is a Uplay only game the version is made for it.
If it’s something like the Assassins creed games or watch dogs it works for both since it starts trough uplay anyways.
Most games still work for uplay maybe 1 or 2 cheats don’t but making a whole new trainer for it seems pointless most of the times.
GOG is mostly a bit different. GOG gets patches later and also sometimes has 32bit instead 64bit versions of the game.
