I know onlink is a mod, but is there any wat to mod it? I've been trying to change up the gateways but it keeps breaking if i make even the smallest change (generally trinity gateway costing one more credit)

I've been wondering the same thing. It seems that for whatever reason, the changes I make to the definitions are not reflected -- and furthermore, they tend to crash the game :/

There is already an active topic about adding/modding gateways. Link.

If you meant actually modding the mod itself, you'll most likely need to have the Uplink DevCD, knowledge of C++, and an .exe de/compiler. And I'm guessing you'd also need approval from the Onlink developers.
