Analysing PSYQ LIBs and OBJs

  • In case you have a directory with OBJ-files extracted from a LIB-file, create an empty PSYQ_LIBNAME_XXX file, where LIBNAME is your LIB-file name (for ex. LIBSND) and XXX is PSYQ version number according to this list.
  • In case you want to batch-import all OBJ-files for a LIB-file or import a standalone OBJ-file (like 8MBYTE.OBJ), create an empty PSYQ_XXX file, where XXX is PSYQ version number according to this list.

Patches format (example here)

  • ~ - is for replacing some pattern in a signature. check field is the original bytes in the signature to compare with
  • + - is for adding some pattern in a signature
  • - - is for removing some pattern from a signature

! pos fields are for the original signature. you should not add appended or removed sizes to them
