https://f95zone.to/threads/r-life-v0-8-5d-patreon-segamex.8428/page-123#post-2605265 using shadow's full save file where you start on the house at the beach, how do you get to yudachi? I would really appreciate it if you could explain it, thank you
Personally, I only played since the addition of the portals and stopped there.
Here's a guide with most steps assuming it's from the last time you left off. (I haven't seen where shadowx25's save is, but if he claims Yuudachi is unlocked, than it's going to be a later phase than initially described.) I will mark which phase you should be on according to the save file.
Phase 1: Accessing the dreamworld
The first thing you need to do is enter the dream world. Under normal circumstances, the dreamworld was unlocked by giving a blue mushroom to the first three female characters in the game: Nyotalia (the mom), Yamakaze (the sister), and Rem (the maid). It doesn't have to be done all at once, but it can be.
The following night, you should have the option to use the blue mushroom on yourself, thus entering the dreamworld. Be advised that only Yamakaze will show up in the dream world if you have fed her the blue mushroom immediately before using it yourself.
Phase 2: Fighting in the dreamworld
Thankfully, the dreamworld has been balanced quite a bit since it's creation. There are still a couple npc's who will fuck you up depending on the circumstances/equipment. In general, you run around fighting the npcs (hostiles are marked on the compass). All the enemies drop varying amounts of coins, some more than others. Easiest targets to take down are the blond guy and the yankee looking dudes with the pompadour haircut. The females enemies can be interacted with when defeated for two separate h-scene each. Since 0.8.5c, all progress in the dreamworld is saved, so don't worry about dying.
There are a few locations to know:
The motel street is your starting area. All of the hostile npcs spawn there in some pattern or another (except for Saitama). There are a few points of interest including
the prostitute (who has several h-scenes for money; you need to give gifts to her first),
the girlfriends house (which is where you will find Yuudachi later), and
the train station (directly beside the traintracks is a board which can be interacted with leading to other locations, all of which require coins to get to).
The store is your primary location for gifts and health items. Kawakaze is also present there (another set of h-scenes after giving enough gifts).
The home street is where you find your actual house of origin. Yamakaze can be found there if brought into the dreamworld.
The workplace is where you can make some easy money once per day. Takao is your boss (more h-scenes, need more gifts et cetera et cetera)
The dojo is a test ground where you can fight against various npcs... not really useful
At the bar is 2b and the dancer, both of which have h-scenes
And the city is the main location for where you need to go. A good number of enemies present each time, but fairly spaced out between one another. The only points of concern here are Roxy's shop and the Z-event. You need to complete Roxy's questline to get the motorbike prior to getting the z-event.
Phase 3: Getting to the Z-event
So, assuming you've gotten somewhat used to the dreamworld, completed a few quests, and generally are comfortable with movement and combat, now you can do the z-event. Over at the school zone is where you activate the event. The z-event has probably been explained enough in the forum previously, but one the event is completed, you should have total access to Yuudachi.
Phase 4: Where Shadow's save should be(?)
Alright, assuming this is where you are, just follow the images laid out in
