The Oxyd series is a fun shareware puzzle/action hybrid that plays like a cross between Marble Madness, Macintosh classic Crystal Quest, and Chip's Challenge.
The game even boasts a plot: overnight, the (digital) life-supporting Oxyds have closed up and no longer emit vital oxygen. As a result, the digital world is threatened by suffocation and only you (as a black marble) can save it. Your mission is to find all the Oxyds in a given landscape and to open them again. Each two of these Oxyds carry the same pattern or color, and they must be touched in sequence in order to remain open. It's not as simple as it sounds, of course-- your task is made much more complicated by the fact that the Oxyds are scattered over a wide area, and they are not easily accessible. Part of the fun in Oxyd is the fact that many of the objects you will encounter in this world have completely unknown effects, and they interact with each other in a complex fashion. It's fun to discover these relationships and what each object's raison d'etre is, and there seems to be an endless variety of new terrains and obstacles throughout the hundreds of levels. With a good balance between manual dexterity and wit, Oxyd Magnum will keep puzzle fans happy for hours, although the large number of obstacles and special objects mean that the game lacks the elegant simplicity of Chip's Challenge.
Note: this download is Oxyd Extra, the last game in the series that was released only on CD-ROM. The game includes only 30 new landscapes, but the best graphics in the series.

Prepared an AI assisted patch for the Windows version of game, which can be downloaded on my github 'https://github.com/Buyukcaglar/Oxyd/releases' page. This portable patch, both provides 'dx7vb.dll' (no regedit registration required) as the tutorial mentioned and makes fullscreen mode borderless native desktop resolution with integer scaled, rather than changing desktop resolution down to 640x480. All of the patch codes and documentation are public and can be found on the same repo 'https://github.com/Buyukcaglar/Oxyd' for your inspection or derivative work.
I am not responsible if anything happens while trying to use the files that are provided, so use at your own risk.
Enjoy!
To play the Windows version on a newer PC (use at your own risk):
1. Download dx7vb.dll from PCGamingWiki
2. Install game and copy dll to game folder
3. Run CMD as Admin and type: regsvr32 "C:\Program Files (x86)\Oxyd extra\dx7vb.dll" (if you installed to a different path put it here instead)
4. If you are going to uninstall the game run regsvr32 /u "C:\Program Files (x86)\Oxyd extra\dx7vb.dll" (likewise edit path if needed, cmd as admin) for extra safety.
5. Enjoy!
Have fun :)
I played this for Macintosh when I was a kid. This is a good game. Mac had a lot of good puzzles and minigames. I wish they had them all for dos as well.
Herz-von-Hessen, please use an appropriate DOS Emulater. Wine is an Windows-API for Linux, so neither Wine nor any Windows version will run this DOS game. I mean, you don't try to run it on your calculator or electric tooth brush either, right? :)
I downloaded this Game and try to play it with wine on my Linux-System, but it seems not to work.
So i tried again under Windows 7 but still no playing.
So i go Back to my Atari ST Computer and play the original Oxyd 1, Oxyd 2 and Oxy Magnum.
