Hey,

I already looked for over an hour into your code but I am really clueless what exactly is needed to open the file.db inside for example the SqlDatabase Browser ? Are you even doing that or do you go by hex editing ?

Also could you PLEASE add Cross Compile to Cmake or add Binaries to the Releases section ? ( I am sorry but Cmake was the reason I quit C developement so I can't make a PR :( ) I tried yesterday to get it working with VS 2017 CE but I failed because I couldn't get Curl library to work XD

Maybe you could add this to the Readme (very easy Boost lib installation): conda install -c conda-forge boost (of course you need Conda/Anaconda installed but it is as easy as apt install)

Sorry for this chaotic Issue,

Thanks for all your hard work, I am really envious about what you've done ^^

OK - lets try to go through issues one by one.

  1. You really stunned me with the first question and I was not able to understand what do you mean at first. db extension has nothing to do with SQL database format. Yes - extension is .db but obviously it is completely different format which is sonys proprietary. Format is based on standard cryptographic primitives though. At some point I am going to describe it on wiki. Anyhow - to answer your question - files.db and unicv.db files have nothing to do with SQL databases. All parsing is done manually.

  1. Again I dont understand what do you mean. Cmake is like de facto standard in C world. Many people already confirmed that project can be compiled on Windows and on Linux (Ubuntu) without issues. Which Cross-Compilation do you mean?

  1. I am not going to add any binaries to Release section at least untill I am done with developement in icv-db-support branch. I see zero reason putting any release binaries there at the moment. It is trivial enough to compile the project and requires minimal effort if you are on Ubuntu. I dont know what else I can advise here. If there is something unclear in the readme - feel free to make a PR. If installation is hard on Windows (I can understand that) you always have an option to compile on Linux. Installing all dependencies with apt-get is a piece of cake.

  1. I see numerous complaints about how hard it is to get boost working. But I really fail to understand that because it is just a matter of executing 2 commands in command line. I guess I will add additional info to readme. Again - if Windows is hard you can always compile on Linux. Installing boost with apt-get is like one command.

  1. I see no reason dragging conda into the process just because you need boost. If you want you can create a recipe for this project. Feel free to make a PR.
