So many spams, craziness, and known people's deaths. :( Quiet yesterday for this old ant. Another Microsoft update day! Apple will do theirs soon.

As far as I'm aware, they still haven't been able to play Doom on an
original GB ;)

This isn't really "Doom running on Doom", like it being able to fire up
a copy of itself to play on an in game/in world terminal. It's just causing the OS
to launch a second copy of the game.

Now if someone could port a copy of Dosbox into GZdoom or something and
enable the dos version to be playable inside the game itself, I would
be much more iimpressed. But why stop there? How about a slightly
modified E1M1 that has a working computer terminal and firing
up Quake inside it? :-)
