RO & RP 1 Installation for 1.6.1

Welcome to the installation instructions for RSS, RO, and RP-1 on KSP 1.6.1.

At this point, however, we strongly recommend using a 1.7.3 installation, a guide for which can be found here.

Please carefully read and follow every word of this detailed guide. RSS/RO/RP-1 is complex and fragile. Not following this guide to the letter will break things and make you very frustrated.

You will be using CKAN as a tool to aid installation. While you're installing really important stuff (RSS/RO/RP-1) CKAN will suggest extra "recommended" and "suggested" mods for you to install along with them. Do NOT let it install those mods yet! Instead, write down which ones look interesting, we'll come back to them later.

Again, DO NOT EVER allow CKAN to install recommended and suggested mods. When it asks you if you want to install these, deselect all options.

§1: Main Installation Instructions

NOTE: This is a guide for KSP 1.6.1. If you wish to install on KSP 1.7.3, those instructions may be found here.

Preparing a New Install

1. Install a new copy of KSP 1.6.1. Do not try to install on top of your old modded KSP. It's not going to work.
2. Delete all files out of the Ships folder and subdirectories, but leave the folders. This is because CKAN is dumb and we need to fix its stupid hangups about things that don't matter.
3. Install CKAN and point it at your new KSP 1.6.1 install.
4. Tell CKAN to allow Compatible KSP Versions of 1.6, 1.5, 1.4, and 1.3 (screenshot).

Realism Overhaul Installation

Note: do NOT allow CKAN to install recommendations/suggestions. NEVER allow CKAN to install recommendations/suggestions.

5. Via CKAN, install Real Solar System and its dependencies.
6. Via CKAN, install Realism Overhaul and its dependencies.
   • Be sure to select FAR Continued.
7. Via CKAN, revert SmokeScreen version to v2.8.1. The version that gets installed automatically doesn't work correctly (screenshot).
8. Launch KSP and make sure everything works.

Realistic Progression One Installation

Note: if you wish to play RP-1, the career mod for RSSRO, follow these steps. Otherwise, if you wish to play RO without RP-1, ignore steps 9-11 and jump to step 12.

9. Via CKAN, install Realistic Progression One (RP-1) and its dependencies. Again, DO NOT let CKAN install recommendations/suggestions.
   • Be sure to select the Custom Barn Kit - RO Build.
10. Via CKAN, install the Toolbar Controller mod in case it didn't get installed automatically
11. Launch KSP and make sure everything works.

Extra Mod Installation

All those mods you wrote down? All the extra ones on CKAN? Yeah, we're going to go ahead and install them now. But first, read the Recommended Extra Mod list and see if anything catches your eye.

Note: if you are playing RP-1, READ THE MOD LIST. Selecting and installing mods from sections 1, 2, and 3 is necessary for the complete RP-1 experience.

12. Write down a list of all mods that can be installed through CKAN. Make sure you check against the official extra mod list that they aren't supposed to be installed outside of CKAN.
13. Use CKAN to install all mods that are CKAN-compatible.
14. Launch KSP and make sure everything works.
15. Install all the non-CKAN mods. (Don't know how to install a mod from Github? Here's how.)
16. Launch KSP and make sure everything works.

NOTE: SSTU does not work in KSP 1.6.1. You can get SSTU tanks using ROTanks and some of the engines with ROEngines. (read the above mod list). Also, Community Tech Tree is not only incompatible with RP-1, it's completely useless, as RP-1 uses its own historical tech tree.

§2: Next Steps

Congrats, you're done. Here's what you should do next:

• Consider trying some of the optional installation steps below.
• Proceed to New Career Setup if you are playing RP-1.
• Consider some thoughtful musings about your new installation.
• Finally, scroll back up and locate the wiki sidebar. The "Getting Started" section contains a wealth of information for help and instruction. It is recommended that you start by reading through the FAQs and then work your way down through the tutorials and resources.

§3: Optional Instructions

Update Realism Overhaul

If you want to have the most up to date changes for Realism Overhaul, then follow these steps:

17. Delete the RealismOverhaul folder from your GameData folder.
18. Download the Master Branch of RO from here: https://github.com/KSP-RO/RealismOverhaul
19. Inside the downloaded zip, navigate to the GameData folder and copy the RealismOverhaul folder into your installed GameData folder.

Install In-Development RP-1

If you want to try the in-development build of RP-1, then follow these steps:

20. Delete the RP-0 folder out of your GameData folder
21. Download the master branch of RP-1 from here: https://github.com/KSP-RO/RP-0
22. Inside the downloaded zip, navigate to the GameData folder and copy the RP-0 folder into your installed GameData folder.

Hide Unconfigured Parts

If you want to clean up your parts list in the VAB, follow these steps:

23. Make empty folders called NoNonRO and NoNonRP0 in your GameData folder. This will hide parts not configured, respectively, for RO and RP-1 in the VAB/SPH while in career mode. Non-configured parts will still be visible in sandbox mode.
