.hdi File Extension

Developer: N/A
File type: Hard Disk Image
You're here because you have a file that has a file extension ending in .hdi. Files with the file extension .hdi can only be launched by certain applications. It's possible that .hdi files are data files rather than documents or media, which means they're not meant to be viewed at all.

what is a .hdi file?

Disk image files or hard disk images created for older NEC PC-98 computer system emulation software like Anex86 and T98-Next are known as HDI files. What these HDI files contain are the older PC-98 video games wherein these files allow these video games to be run on Windows provided there is emulation software that supports it. Two of the most common software that support HDI files and are used to open them are the Anex86 and the T98-Next. The Anex86 is a Windows emulator that contains GUI in English even if it is mainly created and used for Japanese computers. This makes the software easy to use for those who are not Japanese. But if users want the software in Japanese, they can always localize HDF files into Japanese. On the other hand, the T98-Next is another emulator for Windows and a sequel to T98. Since these are Windows emulators, they are most commonly run on Windows alone.

how to open a .hdi file?

Launch a .hdi file, or any other file on your PC, by double-clicking it. If your file associations are set up correctly, the application that's meant to open your .hdi file will open it. It's possible you may need to download or purchase the correct application. It's also possible that you have the correct application on your PC, but .hdi files aren't yet associated with it. In this case, when you try to open a .hdi file, you can tell Windows which application is the correct one for that file. From then on, opening a  .hdi file will open the correct application.

T98-Next is an emulator which happens to be part of the sequel for T98. It supports different types of game formats which include FDI, XDF, DUP, D88, D98, HDM NFD and TFD for FDDs and THD, HDI, and NHD for HDDs. This emulator allows the saving of the game to be done faster by just simply pressing the button and it will automatically save the game which allows the player to go back to the part of the game that he left at a later time. T98-Next works with different types of audios including PCM as well as FM. The development of this emulator was however put to stop in 2002. Using of this emulator however needs large amount of CPU usage, which causes downloading of other applications or just merely using them almost impossible because this emulator will slow down the processing of the CPU.


Dungeon Master, Chaos Strikes Back and Dungeon Master II are some of the games that can be downloaded and installed in your Windows 98-based PC using Anex86, which is an emulator for Windows PCs, particularly computers running on Windows 98. This emulator software is in HDI Format and its Graphical User Interface (GUI) is in English, which makes it easier for gamers to interact with their PCs and is convenient for those who would like to have English-translated versions of Japanese games in their Windows 98-based computers. It is likewise integrated with various modules, wide graphical compatibility, CD-ROM support and a custom boot disk, which is used to store saved games. This software can also be used to emulate early games of the Touhou Project franchise in personal computers under the Windows or DOS platform. Anex86 is also the only emulator that supports a CD-rom for gameplay purposes.

a word of warning

Be careful not to rename the extension on .hdi files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

what is a file extension?

A file extension is the set of three or four characters at the end of a filename; in this case, .hdi. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
