But, this is pretty old code. I’m sure any tweaks you do to that source will compile with the bundled Inform compiler… but… I’m not sure it’s worth it. Whatever you want to do, it might be easiest just to look at the code for reference, get the images, and re-implement in the latest I7.
The problem here is that the package includes “blc.exe”, which is compiled as a 16-bit MS-DOS executable, which can’t be run on a 64-bit Windows system. (The other executable, “inform.exe”, is a Windows console application, so is fine.) There are several ways round this, but none is entirely trivial:
Use the Mac/Linux provided Blorbing tool, which is a Perl script (“reblorb.pl”). Doing this might require some knowledge of Python.
Set up VirtualPC with a 32-bit Windows image and run it all there. The “XP Mode” that Peter refers to is a form of this, with some changes to make it harder to spot that virtualized programs are running under VirtualPC.
I would suggest that the first of these is probably the easiest, at least if you’re able to run a C compiler.
