dmg2img gchdm_203_970.dmg is corrupted

[DPBOX]

Hello, I'm trying to follow this guide https://obsproject.com/forum/resources/streaming-on-linux-using-elgato-game-capture-hd-and-obs-studio.294/ to install this driver so I can use my Elgato Game Capture HD game capture device in my Linux Mint OS, but, after doing "wget http://files.elgato.com/gamecapture/gchdm_203_970.dmg" then "dmg2img gchdm_203_970.dmg -o gchdm_203_970.dmg.img" I get a message saying "ERROR: dmg image is corrupted".

Also, this link https://www.elgato.com/en/game-capture-hd-support on this page https://github.com/tolga9009/elgato-gchd/wiki/Firmware just leads to the Elgato site's home page.

So what do I do? How do I get my Elgato Game Capture HD working on Linux? The resources and guides I'm seeing are not working properly in 2024.

Hi there,

the Wiki page here and the guide you were following were updated 2016, the links are dead. The oldest driver version I could find for Mac was 2.0.5, seems like they've pulled 2.0.3 from their website. You can still try to extract firmware files from the Windows driver. According to our Wiki, you should get version 3.2 here:
https://edge.elgato.com/egc/windows/egcw/3.20/final/GameCaptureSetup_3.20.33.1533_x64.msi

I have found the download link here, if you need to try another version: https://help.elgato.com/hc/de/articles/360027964072-Elgato-Game-Capture-HD-Software-Release-Notes-Windows

If it doesn't work anymore, I can't fix it or provide further support unfortunately. I'm very sorry, but it's been a decade since I worked on this software. I have marked the repository as discontinued a long time ago. Also please keep in mind, before you put too much effort in this: this is proof-of-concept at best and is overall a frustrating experience.

Cheers,
Tolga
