I don't know how I'd forgotten about this till now, but...
In
this thread about the music in NTDEC's
War in the Gulf, several people commented on how the sound engine sounded very much like that in Street/Super Fighter III. Taizou also pointed out that the uppercase font from SF3 was very similar to that in NTDEC's Porter.
Well, I think I've finally closed the loop.
Take a look at the lowercase font from Super Fighter III:
Not only is it drastically different from the uppercase, it's quite literally ripped from Turbo Pascal's graphics library. Much like the uppercase font used in a bunch of NTDEC's games.
Edit: For comparison, the font from Turbo Pascal's EGAVGA.BGI, as viewed in a tile editor:
Incidentally, this font does not include any numbers or punctuation; Turbo Pascal simply uses the video card's ROM to generate those.
