I don't think the greyscale portraits of Toby, Dr. Tenma, and Dr. Elefun are used in-game, I've watched a longplay of this game and there was no cutscene depicting Toby's fate.
Also, that portrait of Astro at the very top left corner isn't used either? Cause' you can obviously tell he's A-posing there...
I find it interesting that the RRF are absent in both games, this and the console versions. I guess the developers knew they were pretty much unnecessary characters, even though they're responsible for giving the name Astro to "Toby".
I wonder if the developers were going off by a early revised movie script where those guys didn't exist yet?...
