Good morning,

So I'm under windows 10, 64 bits, and I use the mod "epsilon v2_52_2_8_2014, 64 bits" that uses Darkplaces to work.

In game my mouse have a nasty bug, it moves all alone down or in another direction whereas I do not touch anything.

I had already had a similar problem with Jagged Alliance 2 in the past and found that it was a problem related to "sdl.dlll", so I put a new version so the "sdl2.dll" but now the game don't wants more to run.

For information I use the "sdl" and "sdl2" provide by the gog version of Quake 1.

Even renaming it to (the new sdl version)"sdl.dll", the game refuses to run, I dont know what to do.

Anyone with Darkplaces and this mod have a solution please?

Thanks in advance.

I cannot give you any specific information about DarkPlaces, but I can tell you that SDL and SDL2 are not compatible, so you cannot replace one with the other without recompiling the program, which requires some changes to the source code in most cases.

A comment on https://icculus.org/twilight/darkplaces/ suggests that it is possible to compile DarkPlaces with SDL2 “Fixed a bug in vid_soft when using a custom compiled SDL2 client”, but you'd have to compile it yourself.

And some good news: Although the last release is from 2014, there is regular development activity visible on svn (http://svn.icculus.org/twilight/trunk/darkplaces/?sortby=date).



Edit: I've got an idea that might work (or not). Xonotic uses a version of DarkPlaces that is newer than the last official release and at least on Arch Linux it uses SDL2. I have not found any information about changes in the engine that break quake support, so it might be worth a try to download Xonotic and use their executable.

Thanks for your reply, meanwhile I found a solution that works.


Actually I noticed that I had the bug when I started the game with "darkplaces-sdl.exe," but now when I start "darplaces.exe" I no longer have the bug.


Thanks anyway for your explanations and your help.
