Don't try and mount the img file. That's the mistake I did too. The previous bin file was at least mountable but this new version can only be opened via 7zip (winrar doesn't work and I didn't try any other archiver. I saw that from the 7zip's menu that the only compatible mode that it opened was C#. I am guessing this has to do with the way the img was made using imgusb and any other software used.) Anyways, there's no other way that I found to open the img and the NTFS file inside, as stated on the main page under spoilers (it was for bin file, but the method still works)
The whole project thrives through ventoy. As much as the work is appreciated, the stubbornness and unwillingness to adapt is not. Not everyone has the need for 22gb worth of various amount of tools that they might not even come to use. It's also not versatile for people who only want to use one or two of the tools present. It would have been better if the images were distributed solely instead of the whole 22GB package. But someone doesn't has that in their mind to think on the advantages for it. Anyhows, I'll be working on a new project myself. If it comes to thrive and I feel that others might benefit from it and like it, I might post it around. Along with a tutorial on how to make ventoy compatible images (I think they already have one on their GitHub), if they are not already, on your own instead of relying onto others. That way anyone is free to choose whatever tools they want and to use and implement into the usb. I like this project. But I don't like to waste a huge amount of time bandwidth and various other resources for the sake of getting one distro out of this project anymore. It's absurd, redundant and just insane at this point.
