There was an update to BYRead-V1.0.4-2018111919 this morning. The main difference I noticed is that there is now a new Dictionary app. The icon shows a capital letter A in a magnifying glass on a book. At first, it is not useful for looking up words, because there are no dictionaries in the Dict folder. The native reading app also has the ability to use a dictionary in the Dict folder, but it also mentions that a dictionary needs to be copied to the Dict folder. While most of the text concerning the update was in Chinese, I did spot the word stardict. With that in mind, I followed this link:
https://sourceforge.net/projects/xdx...ict-form-xdxf/
Once there, I found a 1913 Webster's Dictionary, which I downloaded. Then I copied the files webster_1913.dict.dz, webster_1913.idx, and webster_1913.ifo to the Dict folder. I rebooted the Likebook Mars, then tested it out. Both the new Dictionary app and the native reading app were able to use the 1913 Webster's Dictionary. I'll post this much before trying out other dictionaries.
