Cool stuff!

Nice touch with the Frungy related Starbase report.

The four remix packages you downloaded are actually part of one large collection that counts as one add-on.  
The option to enable them is "UQM Remixes".

As for HD the first one you mentioned (HD-mod) is a fork of v0.7.0 that's still in Beta and not under active development while the UQM-MegaMod is a fork of v0.8.0 which is perpetually in Gamma and is still in active development.
Although, technically speaking, MegaMod is forked from a later point than v0.8.0 but that only matters from my point of view. It doesn't affect you, as the player.

And as for choosing which HD to play, I would have to say that I am very biased towards the MegaMod. 
Not only because it updates the HD visuals to more match Vanilla UQM but there have been so many bug-fixes and enhancements. 

Not in the code but the config files.

I don't know if Arch does anything different than other distros but you can usually find the key configs in the home directory under ~/.uqm/ unless you've specified a different directory through commandline.

Not without knowing exactly what you need.  
Like, do you want one in a star system that has no relation to the plot or do you want to add in starbases for races that don't have them?
I ask because, for the most part, all the planets and moons are procedurally generated by default except for plot specific code that overrides it.

It's much easier to plunk new objects down if you can piggyback off of the plot code like I did in MegaMod.
Saves from having to create new .c/.h files and remembering to tie them into the makefile structure for both GCC and Visual Studio.

Probably would be easier to explain by adding a starbase to a star completely at random then you showing you the work.

I'll be back in about an hour, maybe more depending on how detailed I want to get.

EDIT:

I'll also add comments to code to explain what I'm changing

UPDATE:

This github commit details the basics on how to add a destroyed Starbase to a star system along with planetary ruins and unique lander reports for both.
For purposes of my own I used the Microscopii star system

New post on their blog!

I'm talking about how to  one mod on into existence.(Like in the megamod there are some broken space stations)but thank you anyway.

You have to make an exception for it in the code then call upon that code during planet generation.
You also have to make the graphics and the lander report then link it to UQM via the *.RMP files, one set for vanilla graphics and another for HD.

It's not an easy process.

To give proper credit the destroyed StarBases are from 0xDEC0DE's UQM Extended Edition. 
I merely ported over the code. But not all of it.

I shall don the mask of Rampant Jubilation and Jumping With Ecstatic Glee!

It's fine, both can coexist.

Not much news happens here.

A new message on their blog detailing that they are indeed, back: https://www.dogarandkazon.com/blog/2021/6/10/official-announcement-from-frungy-associates-management-enterprises-inc-fame-xy2bh

Very nice. It definitely is more balanced now and has a better dynamic response.

Did you make sure you have the HD content packs installed?

Try using the MegaMod and see if the problem persists: https://github.com/Serosis/UQM-MegaMod/releases

Because I would really love to know if this is a problem with all mods based off HD.

I'm assuming this is the HD-mod beta?

So, Shiver's balance mod won't work with 0.8?

Is it incompatible? Or would be a trivial matter for him to upgrade his mod for the latest version?

I believe it's currently in testing.

Same for me using Chrome on Win10.

Much appreciated!

All I technically have left to do is recolor the top-view ship modules for both the outfit and status area, make a new set of ship icons for the status and ship portraits area, scale down a set of captain animations, and fiddle with the new fonts some more.
Plus a ton of fiddling to make sure everything fits on screen as best as possible given the files I have to work with.
