Conversion routines for Fire Emblem Heroes asset files.

$ gem install feh-bin

To convert a.bin to a.bin.lz, and b.bin.lz to b.bin:

$ feh_bin_lz a.bin b.bin.lz

If it takes too long to compress a file, try adding -s anywhere:

$ feh_bin_lz -s very_large_file.bin

require 'feh/bin'

Dir.glob('assets/Common/SRPGMap/*.bin.lz').each do |fname|
  IO.binwrite(fname.sub(/.lz$/, ''), Feh::Bin.decompress(IO.binread(fname)).pack('c*'))
end

• Fix <internal:pack>:8: warning: unknown pack directive '<' in '<l' message
• Allow use of Bundler 2.x

• Added command line option -s to feh_bin_lz which skips LZ11 compression

• Added read support for non-LZ11-compressed .bin.lz files

• Fixed double encryption issue in Feh::Bin.compress

• Initial release
