Decision does not appear even with the aforementioned changes

Well, at this point, my only problem is : while creating the Roman Empire from the HRE keeps the succession law princely elective, the vassal bonus of 20 that comes with it disappears. Pretty annoying.

I managed to make it work !

1) go in your CK2 mod folder, usually documents/Paradox Interactive/Crusader Kings II/mod

2) open the file empire of the franks.mod.mod with a text editor, I recommand using Notepad++, which is free and works greatly with CK2 files

3) replace archive="mod/empire of the franks" by archive="mod/empire of the franks.zip"

That way, the box to enable it actually appears on the launcher, but the mod still doesn't work.

4) in your mod folder, open the file empire of the franks.zip with a file archiver, I recommand using 7zip

5) inside the archive, there are now 2 files named descriptor.mod ; open them with Notepad++, and you'll see the content is supposed to be identical with that of empire of the franks.mod.mod

6) one of the two descriptor.mod contains the line archive="mod/empire of the franks" while the other contains the line archive="mod/empire of the franks.zip" ; suppress the first one

7) save the archive

Now, the mod actually works.

In the mod menu I dont have the option to enable it?

I think I figured it out. For some reason the .mod file when I downloaded it was set as path="Empire of the Franks", rather than archive="Empire of the Franks.zip".
Also apparently d_con doesn't exist so that would also block the creation of the RE even if you could see the decision.

I made some tweaks and re-uploaded, but with the way CK2 handles mods there's a 50/50 chance it didn't do anything (The way Paradox handles mods is beyond stupid).

As far as re-downloading goes... I can't either (again CK2 is aggrivatingly dumb)

The command didn't work and when I manually deleted the file from my mod folder steam won't redownload it

Try typing in the event I posted below and let me know what your output is.

I'm not seeing the decision even with all other mods disabled. Does it only work in the 769 start?

Try typing "event LoR.696969" into the console. The only thing I can think of is the mod isn't being read for some reason.

If you get red text along the lines of "unknown event" try manually deleting the mod from your documents folder and re-downloading it.

Weird. I'm playable, have the DLC enabled, I checked the title code through charinfo and it is e_hre. I'm an adult, not a prisoner, nor incapable, and I don't believe Rome has been restored, I don't see it anywhere and I surely would've gotten an event detailing so.

The conditions to form Rome as the HRE are as follows:

is_playable = yes
has_dlc = "Legacy of Rome"
has_landed_title = e_hre
is_adult = yes
prisoner = no
NOT = { trait = incapable }
NOT = { has_global_flag = rome_restored }

(The last one just means no one else has already formed it)

Is there a cultural requirement to get the decision to appear? Say Frankish or German? I'm playing a Roman culture Emperor of HRE. (Started in 769, unified Italy, then got a Kingdom from Frankia to form HRE early.) I cannot see any decision to form Rome.

NO BYZANTINE!!!!
ALL HAIL HOLY ROMAN EMPIRE!

In vanilla, the only way to form Rome is by holding the Empire of Byzantium. Only those of Greek culture however can create it. This mod allows non-Greek cultures to ultimately form Rome through the HRE which doesn't have the same culture restrictions.

So what does the mod do?

Ok, 2 and a half hours later and I think I figured it out lol. Just be aware, your save game may have jumped around.

Doesn't seem to be working for me. Playing version 3.2.1, no other mods active. As Charlemagne I form the HRE but don't see any new option showing up. I assume it's supposed to show up as a decisson?

Unfortunately it is not.

is this ironman compatible?

Lol, thanks! In the same way the Greeks considered themselves the true heirs to Rome, some in the west did too. End of the day, de jure is irrelevant, if you're strong enough, you can call yourselves whatever you want (which is exactly what Charlemagne did).

of course a sperg would say that

Barbarians are not roman, BEGONE FAKE ROMANS.
interesting mod tho
