    I've looked around on the forums and I didn't find anything that could help me, but I did Google it and apparently DMA is short for "direct memory access". My question is what the DMA checkbox for each game in YSMenu is for and if it needs to be checked. I noticed that unchecking it will cause the game to make a save file automatically. Can anyone clear this up for me?

    Edit: Not sure if any of that helped. Think of it as a helper who helps with tedious chores so the master processor can do other things.

    He has probably already found the DMA wikipage himself.

    I think he wants to know why it is possible for people to turn it on and off, if it is for what you say it is, then why isn't it on on default and just hidden in the coding, instead of putting it out there and having people wondering why they put it out there and what its for.


    EDIT:

    I think I found the answer to your question.

    The DMA option is there to give games direct access to the SD card or in laymen terms "games run faster".
    You should just leave it on, unless a game is not functioning properly, then you can try if it works better with DMA off.
