China DOS Union

After running UCDOS 7.0, when running PCTools 9 or NU8, there is a garbled screen and system crash. Only by pressing Ctrl+F7 to switch to the English mode and then exiting PCTools 9 or NU8 can it be solved. What is the matter with this? Can it be solved through the settings of UCDOS 7.0?

Additionally, where can I download patches to remove the time limit of CCDOS 7.0???
Like what Wengier said, it's already the "new DOS era", but there are still restrictions. I'm afraid now it can't collect many money either. It's better to open the source code (I can't understand the source code either, at least the restrictions should be removed), and contribute to the development of DOS in China.

That makes sense. Freedom and being free are the development trends of the new era. But I didn't get screen corruption when using UCDOS 7.0 with PC9 and NU8 under MS-DOS 7.10.

By the way, I'm talking about the patch to remove the restrictions of CCDOS 97, not CCDOS 7.0. I made a mistake!!! Is there any? I found many patches on Google that run once a month, but didn't find any valid links.

Try this CCDOS97 register tool, but I haven't used it myself:

Using a registration machine to register, CCDOS97 will recognize the hard disk. Once the hard disk is changed, it will become unregistered. It is inconvenient to use it in an emergency boot disk. It is more convenient to use this crack. Just decompress it and replace the original file. Open the attachment

Thanks to you two first.

The English NU8 and PCTOOLS 9 use English graphic characters in the 128 - 255 range, which conflicts with the internal code of Chinese characters, so it will cause screen flicker. It seems there is a parameter /G that can make them coexist.
