I've seen what the 3DO BIOS font looks like, and it's DEFINITELY not 16px. But it isn't a color font, per se. Also, I'm not targeting the 3DO per se, or any specific platform. I only mentioned the 3DO because historically it was the one device where the Kanji ROM (it's in Western units too though. Also, Kanji ROMs were common things in the olden days of console and PC gaming [1980s and early 1990s]) is 1MiB. I haven't seen larger. Also, note that there are hardware DEFLATE decoder chips. Also, note that 4096x65536 1bpp uncompressed would be 32MiB. Also, the original PK-ZIP could even run on the 4.77MHz 8088 1981 IBM PC. DOS/V requires a VGA card, which tended to belong to FAR faster machines than that. So, real-time decompression in software for DOS/U isn't a problem. Also, the GBC is clocked far higher than the 8088. And there was one GBC game that went to 8MiB and had FMV. Pokemon Crystal only went to 2MiB. Technically speaking, you could put the TTF2PNG version on the last eighth of the cartridge, and do Unicode fan translations of any game that works on MBC5 mappers (or can be ported to it. Pokemon Crystal's bootleg Chinese fan translation used 16px characters, as did the Star Beasts Pokemon clone, so 16x16 characters can be displayed.)

Now the terminal and phone ideas are ALSO possible. I mean, Unicode DOES have a LOT of OS and technical symbols, as does UnifontEX. In fact, UnifontEX having BOTH "Mathematical Alphanumeric Symbols" AND "Letterlike Symbols" together makes the Fraktur escape code and the Bold code + Fraktur code possible. It also makes support for the earlier emoji (the stuff that was able to fit in Plane 0 Unicode block gaps, and which had the most attachment to the original cell phone sets) possible in conjunction with more recent (2018 and before) ones. Also, my fantasy console wasn't really going to be 3D per se. Basically, it would be a fantasy computer designed to be a better Commander X16. It would have a 50MHz eZ80 (equivalent to a hypothetical 200MHz regular Z80), a full-on GS ROMpler as a soundchip (except using my JummBox SoundFont for the samples, stored in Section 11 of the SoundFont specification's Silicon SoundFonts mode, a mode made for making ROMplers out of SoundFonts, and that SoundFont fits the bill because it is very very close to an actual chip size. It's 0.99GiB, but more specifically, 1020.9MiB. So yes, the sound ROM would be 1GiB, but in 7z it is only 198MiB, but Silicon SoundFonts is happiest with a round number size and direct loading, so thus we end up with a 1MiB font chip in retro style, and a 1GiB sound BIOS in retro style), which I can't decide between making the 64ch that the Atari AMY would have had (64 additive sines), or the 128ch of the last GS and XG MIDI synths, which is also equivalent to adding up the real chip equivalents of some parts of the SoundFont, so I'm probably just going to do a toggle. Also I would make the video modes extremely overkill, basically: Sharp X68000 video modes with Amiga AGA HAM8 color detail across the board.

As for terminals: I use UnifontEX in ALL my terminal apps and text editors. Putting it into a hardware terminal would be a sterling idea. Also, if we are going to do that, it's also an excellent idea to put it into a TDD (used by people who cannot hear or who have limited hearing to communicate over telephone lines), to make them more comprehensive in their character support, which is helpful if languages of a historic nature are involved, and the sheer amount of technical symbols could make tech support a lot easier, because you could show the symbols. Also, Unicode's musical notation is handy here too, because one could send musical notation over a TDD. Also, Plane 1 of Unicode has playing cards (including tarot), dominoes, and Mahjong. Oh, and the huge amount of math symbols in UnifontEX is partially what drew me to it, because I used a very early ancestor of it in my Physics Honors class in high school to input the various symbols used in physics via Microsoft Word's character insert function. Yes, UnifontEX was something I started around my early years of high school. I'm now 21 with a degree in cybersecurity.

With regards to mobile phones: I also say yes, because honestly it can help with texts (Also, this supports emoji from 2018 and before, which coincidentally was the heyday of Tumblr, which is one of the easiest places to find emoji pronouns. Note that some of my pronouns ARE Unicode and are in UnifontEX, so this isn't a judgement. So, if we factor that in, I can say that a significant chunk of emoji pronouns are in UnifontEX. As is the nonbinary symbol, U+1F72C, and some other characters in that block seem to represent some other less-well-known gender symbols. As well as characters in the Miscellaneous Symbols and the Miscellaneous Symbols and Arrows blocks. Basically, having both planes in one font allows for high inclusivity. Also, you have a lot more ability to send technical information over text. I seriously believe that UnifontEX should be usable on mobile as a fallback, since both iOS and Android have no problem displaying it at any scale I've tried.) Also, the DoCoMo 1999 emoji were 12x12. The first mobile emoji set was the SoftBank SkyWalker set from 1997, which had 32x32 monochrome emoji. UnifontEX's emoji are 8x16 when they can fit (the basic smiley and frown are based off of MS-DOS's 8px ones), but the vast majority of emoji in UnifontEX are 16x16px. The "Emoticons" block in Plane 1 which has all the face emoji is special because in UnifontEX, it ALL looks like monochrome versions of the 16x16 forum smilies. So seeing them on a phone of that era is reasonable. Oh also, Inkbox on YouTube made videos where he ported Unifont's Chinese characters to the Apple II and Commander X16. Also, UnifontEX's pop culture references don't stop at forum smilies. The ROFL character is a face with ROFL over the top of it because the diagonals would be a problem otherwise. The ghost emoji is a monochrome version of the Pac-Man ghost (I didn't make that decision), the Korean characters are based on Galmuri Gothic (the maker of Unifont 15.0.06's Hangul was the creator of Galmuri Gothic), which is modeled a bit after the Nintendo DS Korean fonts. And some of the emoji's faces are literally like the MS-DOS smiley face. So, UnifontEX's components were influenced by pop culture to some degree, but not in a bad way. Oh fun fact: The type of sans-serif that Unifont is is actually the same type as both versions of the Discord message font. If you use Firefox and set it to force ALL page fonts on ALL websites to UnifontEX as I have done, and then visit browser Discord, it actually looks fine. Note that Macs will have better non-integral scaling, but if your Windows machine has a 3840-wide display then there is no issue there either. My 1080p Linux and Windows machines have trouble. What I honestly want is for sites such as Archive Of Our Own and other sites with literature available online to have a UnifontEX mode (obviously at 16px or integer multiples of it) just in case people use rarer Unicode, or want to, in their stories. In fact, I want UnifontEX's portion of Unicode to be considered an agreed-upon subset of it as a successor to WGL, as well as for various sites. Also, I want it to be agreed-upon for Unicode art, similar to how Mona/MS PGothic is for Japanese Shift_JIS art. Another use would be as a minimum character set for captioning devices.

TL;DR: there's no texture cache involved.
