Thanks for your inquiry, but no. I have no plans
to release any of my source code to the public
domain - the Hugo code was not released to the
public domain, only to the very small team that
implemented the ScummVM support. I did recently
review the Nitemare code with a view to porting
it to a cross platform IDE. Unfortunately, unlike
the Hugo code, it has large amounts of 16-bit
assembler embedded within it and would be a
nightmare to port. It is on my to-do list,
however as currently it can't run under 64-bit
Windows. Thanks for asking, though.
