To my knowledge there was a Linux port made of Raptor as well earlier. As the version on GOG website is a port from DOS to WIN, I can't help wondering if it was possible to also have a native Linux port of this great game...

You can still buy the original DOS version over at 3drealms.com. (3D Realms/Apogee still is the publisher of the DOS version you see.)
You will get an .exe file though, but this is just an installer that installs and sets up DOSBOX with the DOS version of Raptor. So you can simply run the .exe installer on some Windows machine (or maybe through Wine), then copy over Raptor's files to your Linux machine. Install DOSBOX on Linux, set up Raptor for it and you're good to go. :)

That would defeat the purpose of this anniversary edition. So, does this 2010 version run through wine? Has anyone tested?

While I only have the DOS version myself, as far as I've read, the only difference with the 2010 version is the "improved" graphics. Judging from the screenshots, they simply ran some filter over the original graphics and called it a day.

I just grabbed the game and gave it a try through vanilla WINE. The install runs through setting up the .NET 2.0 runtime, which fails. If you try to run the Raptor.exe or rapwin.exe, they both fail (Raptor.exe is a frontend that tries to access .Net assemblies while rapwin.exe is the main program executable that tries to access the MS Visual C++ 9 runtime which is not part of WINE).
This isn't a DOSBOX packaged-version so the DOS version would need to be purchased for that.

It's really a shame that Loki went bankrupt. I installed today the SDL based linux port of Raptor shareware, and it certainly was a joy to run the game natively (even if it required some lib acrobatics due to glibc having changed so much during the last 10 years). I wonder if it was possible to find & buy used somewhere this original port, if having a new port isn't possible...

Trying your solution...

Almost there. The mono error is gone, but instead I got this:

Tried on wine 1.2 and 1.3.6. Anyway, it works when I try to run rapwin.exe instead of Raptor.exe. Am I'm missing something running rapwin.exe?

Worked great for me under Ubuntu 10.10 and the default Wine it comes with.

I had to run rapwin.exe directly for it to work.

The thing is, running rapwin.exe directly we are missing the extra features of this edition :(

Unfortunately, it doesn't seem like it's the “only” difference — as the original DOS version of the game is replaced by a W32-only one.

I should've checked the forum first, as it wasn't my intent to buy a W32 game. To be honest, I don't even have a native W32 platform. (Yes, I have both DOSBox and Wine, but the latter doesn't seem to perform well for W32 games like this particular version of Raptor.)

rapwin.exe supports parameters, for example -hq, -fullscreen, -2x (or -3x / -4x ), -keyboard (or -mouse / -joystick)...

Or another possible solution: Replace the "Raptor.exe" with this one. On Wine 1.3.18 it works perfect for me...

Great, I'll try it! Thanks, Astorek86!

I have this running in wine 1.3.20, but fullscreen mode seems to have mouse problems and the higher scaled resolutions run too slowly, so I'm stuck playing in a 320x200 window in the middle of my screen. I had hoped that this game would come with DOS binaries as well...too bad.
