Enable and fix minibosses
Please note that this tutorial is a work-in-progress. If you find any errors, please edit the talk page for this article.
This tutorial is for how to enable the actors BOSS1, BOSS2, BOSS3, and BOSS4 become their miniboss counterparts without any bugs so you can put them in user maps and\or CON hacks.
Intoduction
From now on I will refer to the bosses as follows:
- BOSS1 - Ep. 1 - Battlelord
- BOSS2 - Ep. 3 - Cycloid Emperor
- BOSS3 - Ep. 2 - Overlord (Yes, these two are mixed up. Do not try to switch them to what they should be.)
- BOSS4 - Ep. 4 - Alien Queen
The Battlelord is programmed sufficently enough to allow its placement in maps, and the official levels do contain some mini Battlelords. If you have already played Duke Nukem 64, will probably have related that in the levels Hotel Hell (E3L8.map) and Freeway (E3L11.map) there are mini Overlords instead of some mini Battlelords.
When I say "Change it to this:", I want you to copy the text below it in the box and overwrite the text in the box above by pasting it when the old text is completely selected, but in your .CON files of course. There is not much point in changing the web page! 
Also, when I say "Open <insert name of .CON file here>.", I want you to open whatever .CON file the text in the box below is in. I am just stating the defaults.

Definitions
Open DEFS.CON. Search for "define BOSS1 2630".
Look at this:
define BOSS1 2630 define BOSS1STAYPUT 2631 define BOSS1SHOOT 2660 define BOSS1LOB 2670 define BOSSTOP 2696 define BOSS2 2710 define BOSS3 2760
Change it to this:
define BOSS1 2630 define BOSS1STAYPUT 2631 define BOSS1SHOOT 2660 define BOSS1LOB 2670 define BOSSTOP 2696 define BOSS2 2710 define BOSS2STAYPUT 2711 define BOSS3 2760 define BOSS3STAYPUT 2761
These two new defines enable STAYPUT versions of the Overlord and Cycloid Emperor. STAYPUT versions of actors do not leave their original sector.
Strengths and Gamevars
Open USER.CON. Scroll down to here:
define BOSS1STRENGTH 4500 define BOSS1PALSTRENGTH 1000 define BOSS2STRENGTH 4500 define BOSS3STRENGTH 4500 define BOSS4STRENGTH 6000
Change it to this:
define BOSS1STRENGTH 4500 define BOSS1PALSTRENGTH 1000 define BOSS2STRENGTH 4500 define BOSS2PALSTRENGTH 1000 define BOSS3STRENGTH 4500 define BOSS3PALSTRENGTH 1000 define BOSS4STRENGTH 6000 define BOSS4PALSTRENGTH 1333 gamevar BOSSX 0 2 gamevar BOSSY 0 2 gamevar BOSSZ 0 2 gamevar BOSSSPRPAL 0 2 gamevar BOSSLOTAG 0 2 gamevar BOSSSECTOR 0 2
The strengths from mini BOSS2 and BOSS3 was put the same as BOSS1, oblivious because the big versions are the same. BOSS4 is proportional as 4500 - 1000 to 6000 - 1333. The gamevars need to remain the exact same thing as what is shown here.
Note that the strengths do not have to be what is described here. All that matters is that these eight defines exist.

That last bit is changed because otherwise BOSS3 would simply sit there while playing its walking animation.

BOSS4 is a bit more complicated because there is no programming at all for it to be a miniboss.

Conclusion
After that, you should be all set! 
To insert a miniboss in a user map, create the boss sprite you want, and then give it a palette of something other than 0. I recommend pal 3 because pal 21 makes some minor changes to the first three boss' sprites, while the Alien Queen looks red with pal 21. In the end, all that matters is that the spritepal is not 0.
