Great stuff, but unfortunately it's all just graphics files. It would be much more interesting to see the Beast source codes or some development tools like level editors or Psy-Q stuff. But apparently this "confidential" stuff was probably kept in a separate place.
Beast10-LynxAmiga.adf seems to contain a development tool, though. There is an executable named "mandebug" (211.464 bytes) which seems to be able to debug games on the Lynx.
