I want to speed up or slow down some directx games for some test purposes. There are some tools or another methods to accomplish this?

  • Can provide more details of what you want to do. At first glance this sounds like it might be better off on the Game Development site - but if you not a developer I'd be reluctant to move it there.

  • Every game has some sort of own "heartbeat" of its engine, so it would surprise me if there was such a tool to slow down any DX game. What is your real purpose behind this? Maybe we could offer an alternative.

    @tenfour Such a technique would only get you owned in multiplayer, since no multiplayer game waits for frames to advance the state. I don't mind single player cheats.

For some games, the single best way to cause artifical slowdowns is recording using FRAPS or equivalents. Since the encoding burden is mostly constant frame by frame, it more or less causes an uniform delay on the game.

    Now, if you were a developer, you could try and attach on DX surfaces and get some kind of hook to add your own delaying to. How well this works depends on the game itself, however.

I've found a solution:

It isn't free, but really slow down the game. I've tested with desmume emulator + pokemon white rom, and the game speed really changed. I don't know if it really speed up, but slow it does. :)

Now, I know that is possible, I can try develop myself or search free alternatives.

You could try Cheat Engine. It has a SpeedHack feature. It slows or accelerate most games I used it with. I'm not sure about emulators, but if the game is compiled as an 'exe' there is an fairly high chance of success. Also, it is free and open-source.
