Well if you’ve been into Honey Studio like me, you’ve been quite busy 
trying to adapt your game to the new DLC which has been very difficult on existing mods. The new HS Party game does have more positions and maps, allows multi-partner swaps (2 guys+girls action), new costumes, and even tentacles. Other then that it’s pretty similar ONCE you get it reconfigured for English translations and censors.
Honey Studio has stayed the same, leading the way for Neo to be third game within and allowing for some extra animations, more camera, and more eventual capabilities. It’s quite a bit harder to wrap your head around and the studio cards do not work between Studio and Neo. Here’s a video of me just messing around in Neo for the first time.
So my prior instructions before of doing a simple EMF patch and 
the base game are looking quite old now and really need to be updated if you want to stay current. So first thing, if you are an existing HS modder you will want to keep your existing folder and download a fresh new folder that you will want to modify. Instead of updating your old version, just consid
er HS Party a whole other folder and game. It means more room on your hard drive but it will save you from ruining the game or losing what you had previous.
Joe12148 posted a great breakdown of the best way and order to install your game. I would recommend following these options. You can download 
the full DLC’s and then the mods or you can use his multi-part pre-modded game. It’s best to try either strategy and to avoid using the outdated EMF patch at this time. There were several weeks where just getting the game back in English was a major headache.
That strategy of a: Clean Install, Illusion Plugin Architecture, Texture & Uncensors, English Translations, and For Loli (add wide slider and bonemod) is the best course. It is getting much harder to install and mod the game as it was but luckily ATF won’t lead you astray in keeping up with what updates are happening and how to get it working.
Another option from : I’ve made a .Torrent of joe12148’s download in case you prefer torrents. It’s 15GB but I’ll seed for at least a few weeks. ((unchecked, make sure you have shields up or go for the mega upload))
You can also follow these video instructions which mirror what’s above if you like. I hope either of these recommendations work for you!
