J-B

Will any mod that references Jool need to be patched in this way? Contract packs, resource configs, etc… Is there a reason why the planet's name needs to change?

Principia config (tested 1000 years): moves Ruse into a retrograde orbit around Helvica past Sothys, with Neus Nadavo and Regulux moved outward to make room.

The Gael system is unstable in Principia; Iota is ejected. The following patch fixes it (tested 1000 years): In addition, as an alternative to deleting Lili, this patch will move it out into a stable orbit:

Principia patch (tested 1000 years): You may need to add FOR[ZivezdaSystem] to some of the original planet configs to get the patch to apply in the correct order.

Principia config (tested to 1000 years): Delete wormholes Reduce distance from Kerbol by 99% Remove fake barycenter (should only affect UI) Delete submoons (Anomal, Cassini, Russet) Usir system: move Flint, Denali, and Oceanus outward, and Flint made to orbit in retrograde, to keep Maxmin and Denali stable. Poseidon system: move Arkhalo and Hreveldor outward to prevent disruption of Vetinghier Gyro system: apply axial tilt, move moons outward

A config for Principia (tested 700 yrs): Prima-Secunda: Principia doesn’t understand the fake barycenter planet, so Secunda is now a moon of Prima. The actual orbits of the bodies should be unaffected, only UI will differ. Vassa: Tidally locked bodies can’t really have satellites, so C2-1 is made to orbit Cercani. Pequar: C3-1 moved outward to prevent it from crashing into Pequar, Disole moved outward to accommodate it. Nienna: Most bodies moved outward, C4-1 moved inward with eccentricity and inclination reduced.

Archive.org seems to have archived them, eg

In my testing, Geet appeared to remain in a highly irregular orbit around Blas, with Principia throwing an “apocalypse” error indicating the accelerations are too extreme for it to properly model (likely implying a collision would occur). When I tested with 1.25x and 0.8x SMA, it was instead immediately ejected. I didn’t test Subon as thoroughly; it remains in stable orbit for longer than Geet does but otherwise seems to behave similarly.

The orbits of Geet and Subon are not stable with Principia. I don’t know if a stable orbit exists, in the meantime you can delete them like so: @Kopernicus:AFTER[QuackPack]:NEEDS[Principia] { -Body[Geet] {} -Body[Subon] {} } The orbits of the three planets are stable (tested to 600 years).

The latest version of the download has an error. Extrasolar_Textures/PluginData/Kuprus_Height.png needs to be renamed to kuprus_height.png or KSP won’t load.
