What is CHD file?
The file in the CHD format belongs to the Game Files category. The author of this format is The MAME Team. In addition to this file, the Game Files category includes 1509 related files. MAME Hard Disk Image is most often found on 2 operating systems. The file will work on Mac OS, Windows systems, unfortunately not on others. Alternatively, you can use 3 other programs. MAME OS X, MAME, ExtraMAME will apply when it is not possible to use MacMAME.
How to open CHD file?
The main problem with MAME Hard Disk Image is that the CHD file is incorrectly associated with programs. Thus, when you open CHD, the program selection wizard or some other program starts. This problem can be easily remedied.
The first thing you should do is just "doubleclick" on the CHD file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.
Step 1. Install MacMAME
The first step is to check if the computer has the MacMAME program installed. This can be achieved by typing MacMAME into the operating system search engine. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Below is a list of programs that support the file CHD.
Programs to open CHD file
Remember to download programs supporting CHD files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of MacMAME with CHD files
If, despite the installed application, the CHD file does not start in the MacMAME application, you must create a file association. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. Information about the file and the program that the file is associated with are available here. Changes can be made using the "Change" button. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. Checking the "Always use the selected program ..." box will permanently associate the CHD file with the MacMAME program.
Step 3. Update MacMAME to the latest version
If, despite the association of the MacMAME program with the MAME Hard Disk Image file, the file still does not open, check the program version and possibly update it to the newest version.
Step 4. Check for the following problems with the CHD file
Of course, it may happen that despite the above steps, the file still does not work. The most common file problems are:
The affected file may be 0 KB or smaller than expected. Usually this applies to CHD files downloaded from the Internet in case the download did not finish properly. Downloading the file again should fix the problem.
The most common cause here is computer viruses. A virus scan using an up-to-date antivirus program should fix the problem. Alternatively, you can use the scanners available online. The scan should cover the entire computer, not only the CHD file that we want to open. Sometimes virus-infected CHD files cannot be recovered, so make a backup in advance.
A typical compatibility error - the program does not support the older version of the CHD file. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
There can be many reasons for this. The repair method must be adapted to the type of file and damage. Sometimes the program itself has options to repair the most popular CHD file corruption.
The program indicates that the file is encrypted or corrupted. The encrypted file CHD except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. While there is usually no problem reading such a file, it may not be possible to save it. Copying the CHD file to another location will fix the problem.
This problem only occurs with more complex files. In this case, the CHD file is blocked by the first application to open it. Just close unnecessary programs. Sometimes it is necessary to wait a while before referencing the CHD file again. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If nothing helps, please reset the device.
