Those people, who have supported the SMIRF project e.g. by donations and thus are owning a private key set, could write me an email for to get the latest bonus version of the SMIRF engine. Write at ReScharn *AT* gmx *DOT* net.
Because this time nobody is supporting SMIRF by donations, there no longer a public download chance exits. Despite of this the current SMIRF GUI now is able to run also at Wine or Crossover. Its engine's development is going on very slowly. Now a stronger SMIRF version MS-175w is about to be built.
