In Win2000 you could read from and write to memory of any app [1]. Which we did for minesweeper. By setting proper values and forcing the window to repaint we implemented a simple snake game. The body of the snake consisted of bombs and "fruit" you had to eat were flags. I don't remember how we captured keyboard input though.

There were GameHack and ArtMoney, they allow you to track memory address for specific value in game (gold, money, scores...) by input the value before and after changing it, and then allow to change the value at that address.

A modern version of these tools is Cheat Engine, which is brilliant: http://www.cheatengine.org

Watch out for the adware bundled into its installers, though. :(

Yeah.

There is a link on the download page to a zip of the files, without an installer (or the installCore adware/bundleware).

To be honest, that's not really acceptable.

We as a community should be pushing back hard against open source developers who want to monetize their work with malware. There are better ways for them to make money from their work than something that's ethically dubious at best.

I once wrote a tool like that but for gnu+linux. You first have to retrieve the memory mapping of the targeted process by reading /proc/<PID>/maps [1] then use process_vm_read/write[2]

only if it's a different user. you can read/write to your own processes without admin
