China DOS Union

Does anyone know how to use an img image under DOS? I have some floppy disk images of game installation disks that can't be opened with winimage and can't be loaded in a virtual machine. Someone told me to use UNIMG.EXE, but some still can't be processed. Please help. Does anyone know how else to handle img under DOS? I don't have a floppy drive. hdcopy can't be used either.

Try undisk again. Or copy this img file into the virtual machine and use hd-copy to read this file.

Well, this problem also troubled me for many years before. In the era when floppy drives were prevalent, most IMGs were compressed with tools like HDCOPY. And WinImage doesn't support this old compression format.

HOHO. Today I downloaded 3 IMG installation disks of DOS6.22, and even the latest WINIMAGE couldn't open them. There was no way. Then I found HD-COPY2.0A, HOHO, it's really good!!! I've always used HDCOPY. It can also work under WIN. Make do with it. Better than others. HOHO

There is a configuration file in the HDCOPY directory, HD-COPY.CFG.
Open it with Notepad, and there is a line:
/I+ ; compression of IMG files: on
Change this "+" to "-", and "on" to "off" (this on may not be necessary to change, I change it every time), then save the file.
Then run HDCOPY, first use Get from file to read in that compressed IMG, then use Put to file to save as a new IMG file, which is the uncompressed IMG.

In addition, someone previously provided a tool in the forum, EasyImage, let's upload it together. It seems to have some requirements for memory, and you need to set it. I run it with VDMSOUND.

Pass by, give it a thumbs up...........................

There is a tool specifically for img.

I remember it seems to be called img.exe.

After starting, it automatically virtualizes a 1.44 disk from the memory. (It seems that a blue bar appears at the top of the screen, and it is activated by a hotkey ~~~)

It seems to be called SIMG, developed by Chinese people. After running, it stays in memory and presses the Scroll lock hotkey. A blue dialog box appears in the upper right corner of the screen, where you can decompress the IMG to the virtual A drive. Running SIMG again can remove SIMG from memory.

Yeah, now this software can really not be found~~~

It was really classic before~~~

Back then, I relied on it to play the KV300 fingerprint disk~~~

The software at that time:
HD-COPY, DISKDUPE, IMG (CTRL+ALT+S+D+X), Qiuzhen CD Companion, Boyan Image Pass, UNIMG, UNDISK
SIMG, FAKEDISK

Software specifications are all SD (360K)/HD (1.2M)/TD (1.44M)
Now basically use fakedisk and undisk

I used to install Borland C++ with SIMG. I still have this thing now. But undisk should be enough.

Bump

Thanks, I've been looking for this small tool all the time
