Were these changes prompted by compiler warnings? If so could you please publish the compiler output plus the compiler version and platform (and any compiler switcher required to reproduce it)? Thank you.

Well, with current settings there is no warnings, but you can see it with -Wconversion.
I use Clion, so some of the warnings it is clang-tidy related.
My main platform is Linux amd64. I think on amd64 all will be good without type casting, so we can ignore this.

I see the warnings with -Wconversion, thank you. I also see quite a few -Wconversion warnings in simavr do you plan to submit fixes for those to upstream simavr too?

I'm do not have free time at the moment, so if you decide submit to upstream that would be nice.
