    Default CHD files

    Who knows exactly what to do to download a working CHD file? I've downloaded a file in five parts and placed them in a folder in my MAME roms directory. What more am I supposed to do?

    Hi Sotenga,
    Please bear with me as I am posting this from work, and don't have my MAME in front of me, but I believe there is a specific separate folder for your CHD files. They don't go in the ROMS folder.

    Further more, you say it is in several parts.
    Perhaps it is .rar/.par format?

    If so you will need to use winrar or some such program and combine the pieces to make the whole.

    I will confirm all this once I get home and can look at it in person, I'm just going by memory here. But that should maybe help you get going.

    I don't even bother.. the majority of the .chd games even when you get them to run end up going around 5fps unless you got a 8+ghz cpu

    Definitely not worth devoting a couple of gigs too imho. x_x

    So do I.. and I got several CHD's as well But like I said I give up on them and just keep 'em because I got them already. :P

    But like I said, it's PLAYING them that's not even worth it. Have fun trying though

    ghsqb, a slight problem. I don't see a separate folder for CHD files. x_x

    NE146, now that MAME supports Beatmania, you better believe that it won't be a waste of hard drive.

    The CHD file goes in a folder inside your ROMS folder bearing the same name of that game's rom.

    IE: The romfile for NFL Blitz 99 is called blitz99.zip. the CHD file is called "blitz99.chd" and goes into a folder called "blitz99" inside your roms folder. I hope that made sense

    It did make sense. For example, I created a folder for Killer Instinct's CHD. The rom is in my rom folder/directory (kinst.zip), the folder for my CHD is in my rom folder/directory (kinst) and the folder has all five .rar files for the CHD (kinst.part#.rar) Where do I go from here? Do I compress the .rar files?

    Almost. the CHD has to be unzipped/unrared. Use winrar and unzip the five rar files into one kinst.chd file and put that into the directory.

    Cool...maybe I'll be able to try out that FMV fighting game (Atari's unreleased Vicious Circle) someday (the one that's still a huge percentage of my MAME directory's bytes...lol)

    Killer Instinct works! Boo-freaking-yah!!! Thanks to everyone, especially Zektor, for their help! And now, I'm going to try Beatmania! Behold the power of MAME.

    This is actually something these CHD files are excellent for. Say you have one of these hard disk based machines and the HD dies (which isn't uncommon at all) you can recreate the game data from the CHD file and pop a new HD in your machine. Back up and running again! This is preservation at it's best.

    Do you not require a specific model of hard drive, or will any old IDE thing do?

    From what I have been told, this was tested on a few machines with an ordinary IDE HD.
