Downpatching Steam Version + Patch Info
Updated 2 years ago by CptBrian

[section=Steam Downpatching] [quote]Downloading old game versions through the Steam client's console doesn't currently work, so we're forced to use third-party software, which accesses the same Steam file servers.[/quote] • (You may already have this) ASP.NET Core Runtime is required for this to work. Choose the correct installer for your OS (probably Windows 64-bit). [center]https://i.imgur.com/B8XyJyE.png[/center] • Download the latest Steam DepotDownloader (zip file under Assets) and extract it to wherever you'd like to keep it (no installation). • Shift + Right-Click anywhere within DepotDownloader's folder to open a PowerShell/CMD window via the context menu option. Now PowerShell/CMD will use this folder's directory when executing commands. [center]https://i.imgur.com/PXiMrVD.png[/center] • Type a command like this, using IDs listed below to begin downloading your desired game version: [quote]dotnet DepotDownloader.dll -app ###### -depot ###### -manifest ############ -username YourSteamUsernameHere -password YourSteamPasswordHere[/quote] → Press Enter to execute the command. It may also request a 2FA code from your email to log in.

Files should appear in the depots folder with the IDs you used. • Copy&Paste or move those files to the game's original installation folder, overwriting everything; or do some fancy renaming tricks to keep both versions. [small]To find your installation directory, right-click YLIL in your library -> Properties -> Local Files -> Browse[/small] • Play normally. Maybe keep a copy of each installation in-case you need to do this again. [center][small]Setting up Steam's installation folder like this can let you quickly switch between versions:[/small] https://i.imgur.com/fU7UFU2.gif[/center] [section=Patches (Mods can edit!)] 1.03 Patch[small](Jan/23/2020 - Demo & Fixes)[/small]: https://www.playtonicgames.com/impossiblelairdemo/ Notable speedrun changes: • Patched 12-2 Ice Ball OoB (Buzzsaw Falls - Frozen) https://i.imgur.com/qhzMqoR.png ^There's a faster & easier alternative by rolling into the hole right of the door (all versions). • Patched 5-2 Leaf OoB (Gasping Glade - Grown) https://i.imgur.com/v4vhVbz.png • Patched 18-2 Gear Airswim (Pumping Plant - Powered) https://i.imgur.com/14b0cmS.png • Patched 6-2 OoB in the first room by adding collision to all instances of a particular roof object. https://i.imgur.com/O4GZC6z.png • Patched Frog Cave Airswim (Overworld) - The entire southern wall underwater had no collision previously. https://i.imgur.com/G5iYASl.png • V-Sync fixes - Such as: 10-2 lever platforms wouldn't fall far enough to unlock the level if V-Sync was off. Also: 20-2 being "unbeatable" casually with V-Sync off*(slam jump worked)*.

1.04 Patch[small](Apr/14/2020 - NSIL)[/small]: https://www.playtonicgames.com/yooka-laylee-and-the-impossible-lair-update-live/ Notable speedrun changes: • Lair takes an extra second to enter (For technicality sake this makes it the slowest patch). • The state of the Ch 10 tome will occasionally not reset after completing the alternate state which causes 10-1 to be inaccessible and forces runners to complete it first. This is slightly slower and delays the rope zip until later in the run. [Inconsistent] • Lair deaths are more forgiving for new runners. • ?????
