In order to get DRO/DCO to work with ALIVE Factions you have to download the mission
extract the PBO into a mission folder using PBO Manager
1. Go to
for DRO: \sunday_system\fnc_lib\defineFactionClasses.sqf
for DCO: \sunday_system\defineFactionClasses.sqf
Look for

// Check to see if there are a lot of unarmed units, in which case, allow them to be valid
if (count _pInfClassesUnarmed > count pInfClasses) then {
pInfClasses = pInfClasses + _pInfClassesUnarmed;
{
(pInfClassesForWeights set [_forEachIndex, ((pInfClassesForWeights select _forEachIndex) + (_pInfClassesUnarmedForWeights select _forEachIndex))]);
(pInfClassWeights set [_forEachIndex, ((pInfClassWeights select _forEachIndex) + (_pInfClassUnarmedWeights select _forEachIndex))]);
} forEach _playerFactions;
};

if (count _eInfClassesUnarmed > count eInfClasses) then {
eInfClasses = eInfClasses + _eInfClassesUnarmed;
{
(eInfClassesForWeights set [_forEachIndex, ((eInfClassesForWeights select _forEachIndex) + (_eInfClassesUnarmedForWeights select _forEachIndex))]);
(eInfClassWeights set [_forEachIndex, ((eInfClassWeights select _forEachIndex) + (_eInfClassUnarmedWeights select _forEachIndex))]);
} forEach _enemyFactions;
};

Delete all of the mentioned above (It's has it's own section so it should be easy)

Here's where you have to choose
Turn the now edited mission file and turn it back into a PBO and the file itself to it's correct
name and map IE: Dynamic%20Combat%20Ops%20-%20Takistan.takistan (%20 means space here in JavaScript you can also just go Dynamic_Combat_Ops_-_Takistan.takistan) I just recommend this for the sake of making sure things work

Place in your Arma 3 Installation location and put it in MPMissions or Missions (SP)

Mission should now show up when you select a scenerio


Next option which I would recommend place
Copy the contents of the mission folder and go into Documents -> Arma 3 -> Profile or Other Profiles -> Your profile -> Missions -> Create a folder in here with the Dynamic Recon or Combat Ops Name -> Paste the contents of the Mission PBO into this folder.

Open Eden editor -> Find the Mission and open it ->
Optional: add a Game Master Module and set Owner to #adminLogged -> Set Default addons to All Addons (including unoffical ones)

Save Mission as SP or MP (Which ever you want to use)

It should now show up when you are picking missions/scenerios
What this gives you is now a built in Zeus access even you die you will retain it and won't need to use Simple Cheat Menu

Credit to Шейд on Discord for figuring out the lines causing the issue

But be warned this does not fix YOUR units spawning with missing gear on certain factions
- You either have to change them each manually or use a Zeus Mod IE: Zeus Enhanced that lets you copy loadouts to your unit (You can do this at picking class/gear just hit ESC and scrollwheel back to planner when done

Some factions on the workshop may not still work, this has something to do with how the factions are setup ALIVE or Not
