I will look their new Github repo and compare the checksums.
Awesome Miner uses the official PhoenixMiner 5.5c ZIP-file as a base. Then we add their two "nvrtc" libraries to the ZIP-file to ensure our users doesn't have to ensure all dependencies manually. For this reason, all files like PhoenixMiner.exe are identical to the official PhoenixMiner release. The ZIP-file is however a bit larger as it also includes two more dependency libraries (resulting in a different checksum for the entire ZIP-file).
