I assume you can attach the PC speaker pins to any amp? XD

@@FlameRat_YehLon Essentially, yeah. If you know how to solder.

Just wait until you see Area 5150 :-)

Dammit, and I nearly finished configuring this micro-wormhole to send the bitstream. (Physical media was too difficult).

Why would that be? No need for newer hardware?

I was just about to post something of this notion, but you beat me to it, White Dinosaur. :D

Except that no game developer would work this hard on a PC game. It's not like there's a secret switch in CGA that enables this. This is all done with a lot of precisely timed assembly code and register stuffing and it breaks on all but authentic hardware. Everyone else would be writing stuff the way the manuals tell them to.

It's always the case that demo effects can outdo the best the game industry has to offer. Demos don't have to be games at the same time.

Bisqwit I guess you got your answer.

kademan13 Yes, I did. (Published the video on my channel. You know this, but not everyone else who reads this thread.)

OMG nobody replied to this comment? XD

@@FlameRat_YehLon yea, and nobody did in 4 years

@@forind934hmm, I chose this thread because I felt it was a good place to find active fast-paced discussion

The ultimate complement. We were being told to fuck off in other languages too if you understand polish, russian, etc. One of the best nights of my life.

I have a slight understanding of Russian, but I can only read and pronounce it.

I understood that as "Fuckers!", and I think it was shouted in amazement, because he thought it was going to be something particularly lame, but then figured he'd be put on the wrong foot, and we did something cool that he did not expect. So I see it as a compliment.

this is probably the same guy who said "ja pierdolę" after the demo ended. it could mean a million things in my language depending on the tone, but in this case it's basically "holy shit" ;)

Thanks for the translation :-)

Same here...

+Hans ‘Shockwav3’ Meier Well, I think only a small part of the audience would be familiar with CGA and its limitations in colours. A much larger part knows the BTTF movies :)

+Scali Bohemiq Yeh ... just goes with my theory tech-nerds aren't the primary demoscene audience (anymore?).

+Hans ‘Shockwav3’ Meier Well, considering that the PC demoscene didn't really get started until 286+ and VGA were already commonplace, we never expected a large part of the crowd to fully understand the IBM PC and its limitations. Which is also why we did that intro-sequence :) I am surprised at the response to the CGA tricks actually, both during the compo and in the online aftermath.

The 1K part was when my jaw hit the floor and stayed there a while!

The recording is from a phone or something, I don't think it was that lame live. I was there.

+DanielWS424 Indeed. But not this year.

The Man The Yellow hat:Do you like George Curious George: Yes

@@JimLeonard I'm curious if the video memory paging of the PCjr could be exploited to make this even more interesting?

@@doublesigmasigma Definitely, but if a PCjr were the target, we would have done completely different things.

That bloke wrote half the demo, so he was entitled.

While the delivery system was a standard MOD, it is actually more like a SID under the covers due to the technical restrictions we were under. For example, every instrument in the MOD is 256 samples long.

@@JimLeonard You mean that the end tune is a .MOD file (Noise Tracker, ProTracker format)?

@@JimLeonard Does it include the beep music? Thanks for all your answers.

@@julienbraudel7109 sorry, I misspoke. The beeping tunes were composed in monotone, a tracker for the PC speaker. The end tune was a mod file that used special 256 byte instruments, a limitation necessary for the engine to work.

@@JimLeonard Merci beaucoup. Impressive demo.

+Teng Chang One of the nicest comments I got was from a hardware engineer who told me that, had this come out in the early 1980s, it would have set hardware development BACK half a decade because it would have set higher expectations from programmers.

+Jim Leonard Oh that does make more sense! The PC's inherent deficiencies drove hardware development.

Yeah, such an asshole

A few clones can run it, just not optimally.

+Jim Leonard Well, a good clone motherboard with original IBM CGA can run it optimally. Haven't seen any clone CGA card yet that works 100%.

Which is not too impressive, since an up-to-date DOSBox already does that. It's the Kefrens bars and the chipmod player that are most difficult to get correct, because they need cycle-exact CPU emulation.

You need DOS to run it, silly!

TheLMGN it's a 16bits app (if not 8), and since it uses some hacks, not even dosbox will be abble to run it

DanielWS424 Not even DOS, you really needs an 8086 machien WITH CGA, if not gg (I tried on my dos machine and it broke )

+ibm5155 Yeah, that too. P.S. I don't know if DOSBox is ever going to update to 0.75 or higher!

+ibm5155: Let +FairPlay137 applaud BTTF scene. (written from google translate xD)

Fast stock trading. LOL

realtime ray tracing on an IGPU, probably

Well, technically 20 years * 4 coders.

I mean, 4 Titan X Blacks

+Henry Ly It'll not work on that GPU, because it lacks some features, sorry bro

Emulation would be possible, but only if you wrote it to specifically work with the program and probably nothing else.

Henry Ly *kaby lake

Sorry folks, Consoles started coming out in 1972 9 years before this computer was even sold!

they did

Except that creating stuff like this is so difficult. Just because something can shown in a demo, doesn't mean that's practical to build a game around. Especially when the CPU is 100% occupied with cramming stuff in video registers.

I think so. I'm not familiar with that, though

Some LCD panels have trouble detecting the composite color burst output by cga. Try a different display device (or a CRT).

Im using a IBM 5153 CRT monitor

@@wintersgrass The demo only shows full color via the composite output port, sorry.

ok thanks Jim. Clear now :) It was still cool to see it running on my XT !!

@@JimLeonard Happy Valentine’s Day jim

That's because the demo was created for composite color monitors.

now I tred on my TV via composite in and some of scenes are in color other no , stragne

Real CGA card? Also, modern televisions have trouble recognizing the color burst. CRTs work.

Also, make sure you are using the final version which lets you tweak settings for your hardware. It starts with a picture of a CGA card.

yes there is a picture of CGA PCB in color, than is a settings screen that I can choose between 2 color settings and position of the screen and background color , but that hole screen is in black and white :( than the first picture with delorian car is in nice colors like it should be , than intel animation is in vcolor too, delorian screen too. but 1k 16/256 color demos are in black and white , and the girl and creators in the and :( 3D demo is in regular CGA colors, in the credits there is a color too but in strange way ( background is full with colorful "P"s

That was definitely a jerk

It's a form of appreciation

Most of the program is tuned for 4.77 MHz 8088 except the rotozoomer and plasma which run smoother on faster systems.

They are sort-of synonymous. But the 8088 is slower so it is the challenge that appeals to democoders.

@@JimLeonard Yeah main difference is that the 8088 has it's BUI was cut down from 16-bit to 8-bit. Funnily enough technically you can still run that Demo on a modern X86 machine. The problem is not the CPU core itself, but rather every other component like sound card that might compatibility issues.

Another reason might be that 8086 machines are relatively rare, so not very interesting to target. 8088 was the ubiquitious XT clone in the day.

@@Scalibq True The only 8086 machine I have seen on youtube is an old Amstrad IBM PC clone from the mid 80's running a copy of windows 3.11...

***** With an original IBM 5150 and a specific revision of the original IBM CGA video card =p

Brett Bates Thanks for the response, as another few questions, how much would that set me back, or is there a way to emulate the os/bored?

Emulation is downright impossible at the moment, simply because of just how strictly hardware dependent this demo is. You will need an IBM 5150 computer, an original IBM Color/Graphics Monitor Adapter (which cannot be substituted) and that video card must also have a specific revision of the Motorola MC6845 chip, look on the demo creator's site for more specific information, and (ideally) some sort of composite CRT monitor. This will probably set you back a little over $600, easily much much more. Now, most of that is only so you can get the 256 and 1k+ color hacks working, most everything else works even in emulators decently

Brett Bates ok, thank you so much for the information.

Ever heard of the MHz myth?
