Ah wait a second.
The mega links here are currently stand-alone mods that run without any additional help, so this is just unzip + play. Trying to merge them with any version of the game is going to cause massive errors. Though the patch you want to apply still, as it adds a bit more stuff to it.
On the Expanded Crew discord however there is currently a mini version of the mod that is more up to date, even if some things are still missing portation from the mod. My quick tutorial that I gave out was basically for this version in mind, so scrap that, unless you want to go check it out on the newer versions, since there's more characters to interact with. But it lacks many costumes and all, since porting from 1 version to the next is an ungodly pain when it comes to Onis game.
Oh I didn't try to merge this with another version of the game. I tried as the front page said: Downloaded the 0.984h version, unpacked it, then did the same with Patch 7 and tried to copy the game folder over the one in the "base" version. What I get is this:
I'm sorry, but an uncaught exception occurred.
