I am using Cheat Engine 6.6 to attempt to change a value of a string in a program, but unlike in the past when I could change strings to be whatever I wanted, I am having a hard time doing it now, as I cannot make the string smaller or larger than whatever its current size is.

For example, if I have the string "This is a really long string" and I try to change it to "XXXXX", the program instead changes it to "XXXXXis a really long string" and leaves the remaining portion of the string that was not overwritten in place. Likewise, if I try to change the string to "This is a really long string BUT NOW IT IS EVEN LONGER", the newly added content will not be saved. I have also tried saving the found entries as records in the bottom panel and changing their size, and while that appears to work, as the values in the panel at the bottom are updated, the values listed at the top remain unchanged, and the values used by the program also remain unchanged.

What is wrong? I know that in the past I have been able to do this without any problem at all. Even this video (since I cannot post URLs as a new user - youtube[dot]com/watch?v=uRarh5djBck) shows what I want to do working properly. I understand that the game crashes, but at least the change worked for him.

You need to make sure the string ends with a null byte (00).
For now, you'll have to manually set that last byte.
I believe Dark Byte fixed this issue for the next release.

Thanks! Is there a beta that I can download to try this out? I've looked around and have not found anything but I want to check because it is possible that I may have just missed it.

As for setting a null byte at the end of the string, how would I go about doing that? I cannot figure out how to change the strings at the byte level.

Does anyone here know how to do what I am trying to do? I am afraid that I have not made any progress in learning how to do this since the time of my last post.

add a second 1 byte value type at the last byte of the string and set that to 0

or use lua: writeString(address, str) writeBytes(address+#str,0)
