Here you can download a number of Game Maker compatible DLLs I have made for Game Maker. These are not actively developed. I may open source these DLLs.

WARNING: Most DLLs here are not immediately compatible with Game Maker 6 and up. The examples included are mostly for 5.3. You will have to look at the dll calls and interpret your own GM6 compatible code for them.
