Sonic-1-2-2013-Decompilation VS dxx-rebirth

Sonic the Hedgehog (2013) and Sonic the Hedgehog 2 (2013) Decompilation: https://github.com/Rubberduckycooly/Sonic-1-2-2013-Decompilation

Sonic 1 & 2: Here Sonic CD: Here

I recently compiled the Sonic 1, 2 and CD decompilations as flatpaks to install on the Steam Deck (the standalone Linux builds don't work due to dependencies). They install and run successfully, but Discover stops working properly upon doing so. Upon starting up Discover, the following error appears at the bottom:

I compiled the code for you. It's straight from https://github.com/Rubberduckycooly/Sonic-1-2-2013-Decompilation and https://github.com/Rubberduckycooly/Sonic-CD-11-Decompilation. You can download it here. These directly replace the .exe files you've been using up until now.

git clone --recursive https://github.com/Rubberduckycooly/Sonic-1-2-2013-Decompilation.git

And that's the first level of Descent. :) I literally just started a brand-new game yesterday of Descent. DX-Rebirth.

Find a remake of the game ported to a modern engine. https://www.dxx-rebirth.com/ appears to be a port of Descent 1 and 2 to the Source engine. It won't help with you running the 3DFX version, of course, but this might actually be better?

I loved this game. You can still play it with DXX Rebirth

I would look at DXX rebirth, https://www.dxx-rebirth.com even if you just want to add the expansions to your steam version, you should be able to use its instructions to add the levels to your version.

Descent 2 - so long since I last played any Descent game I forgot how the experience was, but hey there's a source port!

Or if you still want to play the originals, the DXX Rebirth mods also make it easy to play on modern computers!
