Hi. Have installed Tex Murphy Overseer. But get mpeg2 driver error, and cant find any solution to this problem.
Windows 11. Can anyone help me?

Hello, not sure if you are still interested, but here's how I got this INCREDIBLY fickle game to run on WIndows 10. It takes a bit of tinkering but it is nothing insurmountable even for a relatively low-tech person. There are three issues with this game - the mpeg2 error, the in-game midi music and the semi-transparent in-game obejct textures, at least those have always been present for me on a new install.

Right, assuming you've installed the GOG version and get the mpeg2 error you need to install the latest ffdshow filters. Apprenlty, no other codec will do, I tried K-lite and others - no dice. So download ffdshow from Sourceforge or elsewhere, my version is ffdshow_rev4532_20140717_clsid, but anything new should work. Now once you install it, you need to go into the video decoder options once it asks you at the end of installation if you want to do so. There look for Mpeg 2 and make sure it is checked and the option libmpeg2 is chosen. OK this and close and that should take care of the mpeg2 error.

In case you have no midi in-game music you need to download a midi player. CoolSoft VirtualMidiSynth is the go to software for this - free and easy to install. Just get the latest version. You also need to download a soundfont, kind of like an musical instrument set for the midi software to use, get the FluidR3_GM from the CoolSoft website (just scroll down on the download page), make sure you get the uncompressed version as decompressing sfArk files is just an unnecessary extra step better avoided. Place this file somewhere where it will not be in the way, Documents is the best. Also it is necessary to download the MIDIMapper from the same website, newer Windows versions will not allow the game to "see" the midi player without it. Install the VirtualSynth first (it will ask you for the soundfont file, make sure you click APPLY), then the MIDI mapper and choose VirtualMIDISynth #1 as the default MIDI device when asked. Apply and that's it. Make sure VirtualMIDISynth is running every time before you run the game otherwise no music for you. In case you still don't hear in-game music go into settings in the game and choose VirtualMIDISynth as the device in sound options. That should take care of the music problem.

Last, but not least - the textures. Download the latest DGVoodoo soft, unzip the file into some neat folder somewhere and go into the MS folder and x86 foler and copy all four DLL files from there to your Overseer folder (just left click on the icon on the desktop and choose open file location to get there straight away). Make sure you COPY the files, do not move them. Once this is done run dgVoodooCpl application and in the Config folder/Running instance line click add, the browse to your Overseer folder. Once it is added, go to the DirectX tab, leave all as is just unclick the dgVoodoo Watermark checkbox and click apply. Not necessary to do, but if you don't you will have a dgVoodoo watermark image showing in the game.

And that is it. now the game should run as it is supposed to, dgVoodoo also helps to stretch out the image to fullscreen, which is much nicer than the black sidebars you would get on wide angle monitors otherwise.

Hope this helped.
