Shouldn't those be
   file.seekp (0x494844, ios::beg);
   file.seekg (0x494844, ios::beg);
or am I missing something obvious, like the default base being hex? I've
done no more C++ than reading some books a couple of years ago

Anyway here's a "perl at bash prompt" version

$ perl -pi~ -0777e 'substr($_,0x494844,1)=chr(0x7)' tnt.wad

pros: look how short it is!
cons: it sucks the whole file into memory, changes one byte and spits it
      out again so it's grossly inefficient.
