Doom "running" on TempleOS

dunno. i want to see HolyC source. very suspicious. sound is especially suspicious, considering that TempleOS has no soundcard support, only speaker. of course, they could implement SB driver, but…

Yeah, I don't see any reason why they wouldn't publish the source if this was legit. And taking a look at this channel's other content I realized they are mostly focused on publishing pure garbage. I think this video is just a very, very bizarre clickbait.

I don't know what TempleOS is but I think the 'got doom running on absurd technology' crowd has been skating by recently with simply using anything with a digital display as a monitor to run doom while the game itself is being played from a more practical device.

I think it's a bit reductive to describe Terry Davis as a "fundamentalist loony." He was a clearly talented programmer and even if his ideas on religion were out-there and not really what I subscribe to I think he deserves to be known with a bit more respect. He suffered from a severe mental illness that eventually claimed his life. Nonetheless TempleOS is, even if not really practical or useful for anything, a fun and cool thing and I'm glad it exists.

If you've never heard of him or of TempleOS I do highly recommend watching this documentary on him, he and his project are quite fascinating.

actually, this is not completely right. ;-) TempleOS is fully-featured 64-bit OS, with proper multitasking, and very powerful CLI (you can call compiled HolyC code directly from CLI). it also has a working window system, and a lot of built-in documentation, which can be easily browsed, and in many areas much better than *nix mans.

TempleOS is very stable and usable (if you will consider its architecture, and won't go crazy modifying system areas or working directly with random ports; yet allowing such things is not an oversight, but a conscious design decision).

it surely cannot run Doom as-is, though, because TempleOS has its own C dialect (HolyC), and its own compiler for it, written from scratch. but it is definitely possible to port Doom code to HolyC. yet it will require quite huge amount of work, both in converting Doom to 64-bit clean code, and to write at least audio drivers for SoundBlaster (because default TempleOS supports only PC speaker). one will also need a dithering engine to convert 256-color Doom screens to 16-color. (this is what TempleOS is using, only 16 color mode. not 16-bit color, just 16 colors! ;-)

He should've just ported Catacomb 3-D instead. That's EGA and PC speaker, so it doesn't need any special tricks. It's still impressive if this Doom port is legit, but ultimately kinda pointless.
But I found another game recently that used interesting tricks on an old 8-bit computer:
www.cpc-power.com/index.php?page=detail&num=13359
This computer has 3 official video modes. Some demoscene releases make their own video modes by tweaking registers in CRTC or Gate Array chip, but this game works a little differently. It was already very common from the early days of Amstrad to mix two different videos modes on the same screen, most notably mode 0 and mode 1 in two different vertical parts of the screen. Mode 0 is 16 colors and low-res, so good for game graphics, and mode 1 is 4 colors and medium-res, and suitable for status bar and text (the last one, mode 2 is seldom used in games because it's only 2 colors and highres).
Anyway the trick he used in this game was to alternate every other line between mode 0 and mode 1. Like one guy in the comments says, it ends up looking more like an Atari ST game than 8-bit Amstrad.

Just because there's a Chinese guy and a dragon doesn't make it mahjong. It could be Shadow Warrior.

Chinese food in the west is adapted to western palates. Some people distinguish a separate "Chinese American" cuisine or whatever it's called.
But either way it's a sign of an inferior culture that you don't have your own takeaway food.

if Chineese culture is so superior, why didn't they invented Doom first?
