How to downgrade to previous version.

[Teirdalin]

So because some essential mods require the previous version, I spent the day trying to figure out how to downgrade the version. So here is what I found.

First off, open up chrome and go to steam://open/console

This will ask if you want to open it in steam, click yes. It'll give you the CONSOLE tab.

Next step is from a user named StepS over on another page, because it seems older manifests have a check that have an issue with being ran from the steam client now so you need to use cheat engine as a workaround, here is his short guide-

"1. Run Cheat Engine.
2. File -> Open Process -> Steam
3. Set the right-hand settings to the following:
- "Memory Scan Options": steamclient.dll (just keep pressing S when the drop-down is open to iterate through each and find it quicker)
- "Value Type": Array of byte
- "Hex": checked
- "Writable": unchecked (!)
- "Array of byte": D0 84 C0 0F 85 2E FF FF FF
4. Click "First Scan". You should get a single Address and the searched Value next to it.
5. Right-click the Value -> Change value of selected address(es)
6. Enter new value: D0 84 C0 E9 2F FF FF FF 90
7. Click OK. Done. You can now exit Cheat Engine and are able to downgrade games without the "Manifest not available" error."

Now after you've done these steps, go to console and paste in

download_depot 457140 457141 6703262714828141808

This will download the previous version of the game into steam\steamapps\content\app_457140\depot_457141
It won't say it's downloading it anywhere but you'll see on your downloads tab that it is downloading.

Copy/Paste those files over your installed files, and congratz, you got your game back to working.

If you need a different version they're over on https://steamdb.info/depot/457141/manifests/ just replace the 6703262714828141808 with whichever manifestID of the version you want.

Now I can get back to my colony.

FWIW (and not talking about other games, just ONI) this is not a solution. ONI mods are not versioned and thus cannot be tied to an ONI version, you'll have exactly the same problem except in reverse, you'll get new versions of some mods that *probably* aren't compatible with the older game version you've forced.

Only solutions are to wait for your "essential" mods to update or force a game downgrade and also force mods to not update. Somehow.

Unless Klei adds mod versioning to ONI you're stuck with broken mods either way, I say just wait.

Well in the specific situation, it did work. Unless a mod is already interacting directly with new content that has been added, newer ONI mods should generally work with most older versions of ONI that are not like major overhauls of systems.

True. But it's also true that many mods need no updating and work fine even when the game updates. Unless as you say something major changes but this is also dependent. They recently updated a bunch of things with logic ports, many mods broke because of this and it wasn't necessarily a quick or easy fix. Many mods didn't break because they don't use logic ports.

Regardless, unless Klei implements mod versioning and support for tying mod versions to game versions, you can't really eliminate the issue.

As of now, there's no hit for "D0 84 C0 0F 85 2E FF FF FF". Any ideas?

Doesn't the tick in the game options work?

The given byte array doesn't work anymore.

- "Memory Scan Options": steamclient.dll (just keep pressing S when the drop-down is open to iterate through each and find it quicker)
