I was wondering if there was an OE patch for HL2 episode 1 and 2. ---

Disregard that. I misread the version number. I don’t think 4104 has bhopping. Episode 2 particularly I don’t think ever did. ---

Sorry to say but, I have been searching for the past few months for any way to get HL2 EP1 on the OE but the truth is no one owns it anymore. There used to be an old mod but that has been removed. There is a download I can send you with HL2 EP1 on OE but it doesn’t work and when I load it up it comes up with an error and crashes. ---

Don’t put it into your steam folder as a mod. The only Source Unpack that is in the form of a mod is Half-Life 2 4044. ---

You should just be able to extract it anywhere and there should be a batch file to launch it. I meant to download it the other day and test but my download kept failing. ---

I grabbed the latest Episodic Unpack from the forum thread and it all extracted it to a folder on my desktop and it ran fine. Steam did need to be running though. If you’re not getting any errors though I’m not sure where else to start looking. Maybe try opening a command prompt in the folder you extracted it to (Open the folder and type `cmd` into the explorer address bar) and run these commands: ```bash echo 380 > steam_appid.txt hl2.exe -game episodic -novid -console -window ``` And see if there is anything output/logged there. ---

It’s running now, however, the source unpack doesn’t seem to be what I’m looking for. I’m looking for an old version, preferably the original Orange Box release, that allows me to bunnyhop and prop-fly. ---

v4044 is the oldest Half-Life 2 version with those features, which is available on the unpack page. @Centaurium may have an old copy of ep1 with those features, so we’ll need to see what he comes back with. Episode 2 never had any of those features, unfortunately. ---

The only reason I’m being persistent is because a popular Youtuber made videos with the old versions of episode 1 and 2 and showed off his speedrunning skills. [Next page](https://forums.sourceruns.org/t/old-engine-patch-for-episode-1-and-2/3049.md?page=2)
