That’s a subtractive blend mode. Unlike multiply, in which all pixels are darkened at the same rate because it’s being multiplied, from 100 to 0, subtractive, which is what the PS1’s really only capable of processing, is subtracting from the value of the pixel, from r, g, and b.
Try linear burn or subtract in photoshop to see it at work. Hope this helps.😉

The need for IntelliFont (FAIS) format fonts kind of fizzled out, and Agfa concentrated on its industrial printing side from the late 1990s. Initially, Adobe wouldn't give a licence or open up their vector font formats to anyone. This prompted several competing vendors to produce vector font libraries in their own formats. Agfa-Compugraphic's IntelliFont was ...

It can be a direct result of that, yes. I've summed up the clock durations of your routine and it comes up to 344 (plus a little bit for entering the interrupt, and for your OUT macro), which is a pretty long routine. I don't think that's the problem though since the duration of a line is fixed at 456 clocks. (If you exceeded that, it would be really bad.)

Where did the 80x25 text terminal size come from?
From IBM punch cards. Very slowly, but relentlessly.
Before the mid-1970s there were a variety of line lengths in use. American typewriters were generally considered to type at 72 columns, although that was up to the user and anything from 60 to 90 would be seen. Teletypewriters and similar systems almost ...

Yes, you can do that, and it has been done on the Commodore 64 before. The prime example is the below part of "Wonderland IX" demo by Censor Design from 1992.

TL;DR While multimedia capabilities were not considered a liability for business computers, some of the qualities that were lacking in the early multimedia-capable computers were enough to disqualify them for most businesses.
I think it is important to first understand there was not just a single market for desktop computers in the early years (roughly 1977-...

On the other end of the MS-DOS era from CGA and EGA games and Chip's Challenge (1991), there's late VGA games like Tyrian (1994) and Rayman (1995) that look like this:
How does Tyrian manage to have sprites, the large grey platform, the trees, semi-transparent clouds, semi-transparent orange explosions, and the dynamically positioned real-time ship shadow ...

The WX can be freely changed during a frame but the WY cannot. From pandocs:
writing to WX, WY etc. mid-frame shows a more articulated behavior.
For the window to be displayed on a scanline, the following conditions must be met:
WY condition was triggered: i.e. at some point in this frame the value of WY was equal to LY (checked at the start of Mode 2 only)
