Ah! The licensing for v2.14 is a bit different:

This is different from v2.12, which said:

Nothing in 2.14 says anything about not being allowed to redistribute
modified source/binaries... so if we want to make a Stella-specific ver.
of DASM, we can base it on DASM 2.14, as long as nobody sells any copies
commercially. Technically, we don't even have to talk to Matt about it,
but I would anyway, out of respect...

I'm thinking of getting in touch with him, to see what his opinion on
the Olaf Seibert mods to v2.12 is... some of that stuff is handy. I'd
like to port those to 2.14 (probably will be very simple).

According to dasm.doc, the source code is ANSI C compliant, so it should be
more portable than 2.12, not less... anyway nothing DASM does is platform-
specific except maybe some assumptions it makes about stuff like the size
of an integer (which may be fixed in 2.14). Most likely, the source code on
his page will compile on DOS, Win, and any Unix, with no or few modifications.

Man, this is good news...
