Ghidra 12.1.2 headless decompilation of Steam client version 1788652215: - decomp/linux64_steamclient.so, ubuntu12_32_steamclient.so, ubuntu12_32_steam: per-class pseudo-C (RTTI class recovery + Class::Method string naming), functions.tsv and strings.tsv - decomp/protos: 107 .proto files and descriptors.pb extracted from steamclient.so - decomp/steamui: prettified Library UI JS; steamclient_js_api.txt lists the SteamClient.* backend API it calls - tools/: decompile/recover/export scripts and proto extractor GCC exception-handler analysis is disabled: it truncated ~47% of function bodies on these binaries.
