183 upstream commits. Ultima's data_archive.cpp was folded into Common::load_engine_data, which opens ultima.dat and checks its version.txt the same way (common/engine_data.cpp:273-279). No dists/ or gui/ file changed, so the bundled hashes hold. Adds japanesemacfonts.dat, which the Mac GUI reads for Japanese fonts and ScummVM does not ship.
Covers ROCKNIX scummvm-sa and AmberELEC SCUMMVMSA, SDL2 builds with SDL2_net. Pinned to master 6f7b060d with hashes of the files there. Adds eem.dat, macventure.dat, fonts-imgui.dat, wwwroot.zip and monkey4-patch.m4b to the set the SDL1 build reads.
