I manage to write a frontend for the flashing tools, here : https://github.com/Nolaan/Companion/releases , there is the prebuilt 64bits binary and the source code. Let me know how can I improve.
Is there a Makefile or config type script?
It’s Qt project, you just open companion.pro with qt creator and compile it.
Otherwise I use GitHub’s “Release” feature
download the compiled version here : https://github.com/Nolaan/Companion/releases/download/v0.5/companion.7z
(Currently only 64 bits)
