You woke me up, thanks! Now I remember the sci-fi novel by Karl-Heinz Tuschel named "Der purpurne Planet" (The purple planet), located in a system around a star with distinct purple color, mentioning some strange psychological effects on humans used to a rather yellow sun ("purple euphoria" causing complete exhaust).

It would probably be implemented best as pixel shader effect...

Getting even nerdier... The GDR (eastern Germany under russian administration between 1949 and 1989) used an own variant of CP/M as OS for their education computers (BiC = Bildungs-Computer) in advantaged schools and called it SCP; I doubt they made that one from scratch. It supported 5.25" floppies with up to 624 KB (DS HD format) and graphics close to CGA or low-res EGA. We used it to run Turbo Pascal 3 with WordStar cursor movement (Ctrl+ESDX). Well, it didn't take long until CP/A spread in the class, with up to 780 KB formats and a more powerful CLI named "power" (similar to 4DOS). That's even more remarkable as it was quite hard to obtain any floppies, that usually required access to an "Intershop" where you could buy goods from the capitalistic market for token money based on Mark of the FRG as convertible currency (Mark of the GDR was a token currency itself). More common were homecomputers of the KC 8x series with cassette loader. The most common game there was an ASCII+block art text adventure called "Tatum" or similar where you had to explore a building with lots of fatal traps. When you died ... load again from cassette ... and get a fresh coffee in the meantime ...

Some "VGA demos" were so extremely optimized, including self-modifying code, that they failed due to instruction cache and pipelines when running on a Pentium, supported 486 at most. Some "DOS Emulators" also had issues with them. I believe the "Second Reality" by Future Crew was one of these picky demos. (Gosh, I love its soundtrack; but there is no good remake of its LQ samples, the official remake is worse in many details.) And then there are C=64 emulators, some simple, some elaborate; CCS64 and Vice are among the few which ran the "Second Reality" remake by Smash Designs. They simulated even the BIOS screens during a PC boot and matched the sound card selection in the demo to support the SID! :D Just recently I found a graphic demo which is so extremely optimized for real hardware CGA in original IBM PCs that it "won't run on any CGA emulation": 8088 MPH — as old as skool can be ... retro for the heck of it.

Why do I remember "The Last Emperor" here, the scene when Puyi threw his pet mouse? And, furthermore: What happened to the Mouse?

That was quite the smartest move of Bill Gates at all: To have it bundled with IBM PCs. May have been a risk, its public acceptance was hard to predict; PCs becoming a best seller was the big luck of Microsoft. _ Uh. Cyrix. And only 25 MHz. The 386SX had 40 MHz and we had to shrink the window.

Needs nore cowbell.

Yes, I did, on a 386-SX (no FPU). I had to shrink the window to get it fluid. And regarding file managers ... eehm ... Norton Commander 2.0 was probably the most widespread "decentralized backup" ever. ;) And regarding config optimization: My record with QEMM was 634/640 KB free! With HIMEM/EMM386, still 620 KB.

There were no screenshots visible for me in your spoiler (maybe this image hoster prevents embedding in other sizes?), so I quoted them as links...

Please fix your URL to make it clickable, there is an additional linebreak included.

*wiping dust* A pity I found it so late. So I have to tell something epic about it... I think that Plutonia1024 is "the TARDIS of DOOM megawads":

Meh, I don't receive email notifications anymore, keep missing updates until I remember to check here. I believe I can't mark post as "have read it" anymore...

Wanna see it after improving light levels. Looks promising already; there are a bunch of creepy game scenes in hospitals or similar areas (e.g. Postal² zombie mod: Eternal Damnation) I already enjoyed, hope to enjoy yours too.

A pity I don't know what it is. But it looks like I missed something really important. Especially the German name of the weapon is interesting. Not sure what's to the left of the room, a table with a red cloth? It looks cut off at the left side. Render error?

Too cubic, too much like MineCraft, for my taste...
