Edit Bonus Techs

[Emma de Normandie]

Can you edit the bonus techs for nations? Say, if I wanted Japan to have the quadruple turrets bonus tech instead of France, can that be done? Can you make any technology a bonus tech for any nation of your choice? Very curious.

Each nation definition in the BNat*.dat file for standard powers or in the *.nat files for custom powers has a couple of lines starting with BTL. Those are the lines that define the bonus technologies for that nation; the number following the equals sign is the tech ID number. Tech ID numbers can be found by locating the technology in ResearchAreas2.dat; the ID number is the last number before the tech description.

For example, the entry for Cross Deck Fire is:

Cross deck fire;1905;N;70;6;605;Enables cross deck fire for staggered wing turrets (positions D & F or E & G)

The tech ID number for this technology is 605.

I did this for CSA, overwriting what was there with 4 different techs. Changing CSA,nat, CSA,nat2, and CSA1900.nat did nothing. Finally I edited CSA.n00. That did not remove the original bonus tech even though I overwrote it, while of the 4 techs I insert, the ones in the BTL1, 2, ad 3 slots appeared 2nd, 3rd, and 4th when I started up a game. The tech in BTL4 did not appear.

I have done this by editing saved games a few times. Figuring out what each tech is can be a little tricky since they are numbered instead of named, but you can add or remove bonus techs on any nation.

Yes. Did that carefully and checked my work. Got the anomalous results reported.
