First of all we need some mods, and we'll download these from NexusMods.:


Fluffy Manager 5000
REFramework(REFramework (Collab Trainer compatible))
SSSiyan's Collaborative Cheat Trainer
COOP Trainer (for Devil May Cry 5)

We need to create folder for this app, whereevr you want, the main thing that you should find this easy. After this we extract all files, so it will look like on screenshot(Exept folder "Games", which creates after second step ).







Open mod manager and choose DMC5

After this we go to next mods.

So download manual archive, drag and drop file (dinput8.dll) from archive to game folder in Steam. It's gonna look like that:



You can make sure that you download REFramework rigth, when you start DMC5 and see that menu in left part of your screen:



REFramework (NOT Collab Trainer compatible)

And go down

That mod make SSSiyan's Collaborative Cheat Trainer and REFramework compatible.
Drag and drop from archive first folder(REFramework) to "Mod Manager\Games\DMC5\Mods"(which you can see in Mod Manager folder between Data and Legalese folders)

When you download this mod, you need darg and drop full archive in folder "Mod Manager\Games\DMC5"

And here you can see mods shich you already download:

After installation previous mods you need enable these(SSiyan's first one).


That mods looks when them enabled


After actication in DMC5 folder you can see few new folder, we need go to "Devil May Cry 5\reframework\plugins" and check for "sssiyan.dll" and drop here "coop_trainer.dll"(which you install and find in file path(in DMCVTrainerDLLByDanteRaz0r archive) "Downloads\DMCVTrainerDLLByDanteRaz0r-353-1-3-11-1695850407\reframework\plugins"

After all previous actions, we need start DMC5 and enable few options.
In REFramework panel klick on lower button(Script Generated UI) And enable these options(Last one needs if you and your friend in different regions.):

To connect each other you need just choose same mission and same game difficult level, wait few minutes(or less) and you can play together!
