Patched binaries
On Linux and OS X, users of patched binaries may have to find the relevant section in symbols.xml, and add a new line with the checksum of their executable::
<md5-hash value='????????????????????????????????'/>
In order to find the correct value of the hash, look into stderr.log; DFHack prints an error there if it does not recognize the hash.
DFHack includes a small stand-alone utility for applying and removing binary patches from the game executable. Use it from the regular operating system console:
binpatch check "Dwarf Fortress.exe" patch.dif- Checks and prints if the patch is currently applied.
binpatch apply "Dwarf Fortress.exe" patch.dif- Applies the patch, unless it is already applied or in conflict.
binpatch remove "Dwarf Fortress.exe" patch.dif- Removes the patch, unless it is already removed.
The patches are expected to be encoded in text format used by IDA.
Live patching
As an alternative, you can use the binpatch dfhack command to apply/remove
patches live in memory during a DF session.
In this case, updating symbols.xml is not necessary.
