- A C64 Demo quite like no other. Here is what's possible with a ram expansion!
Released at Breakpoint 2010 - Ranked:1st
I have included the long intro at the end of the main demo
"This demo requires a 16MB REU. It does work in VICE and 1541 Ultimate, and should also work on Chameleon once that is released - or a modded original Commodore REU if anybody ever manages to actually extend that to 16MB! ;-)"

A lot of this is just video playback made possible by the extra memory.
No problem there, the music kicks ass and the style is very nice, so overall, I really like this.
The technical detail deserving note is the new interpolated graphic mode, offering all 16 colors in 320x200 without apparent limitations (normally you are restricted to only 2 color for each 8x8 pixels block). Each single frame of this video is more colorful and/or defined than the C64 is usually considered able to do. Once we said that, ok , the anachronistic/absurd amount of RAM in the REU does the trick maybe too easily. But this is still something that was interesting and funny to be seen!
Would the higher rez work on a stock reu? Or to put it another way how much ram would you need to achieve the effect?
@@LordmonkeyTRM This effect for a single frame or limited frames is available on a stock machine. The thing is, that graphic data of a whole movie is huge. I think a stock REU of 512kB would fit the Rick-rolling clip (that's just an educated guess, I didn't do any actual calculations)
@@LordmonkeyTRM The UFLI graphics mode has nothing to do with the REU and works on a regular C64.
The additional colors are done by rapidly flipping back and forth between two frames, right?
rick rolled from a c64 demo REALLY ???!
Did not know FMV was possible on a Commodore.
This technically should be a C16,448 demo.
Hehehehe :)
Note that the C64 should have been named C64.5, as it has, in addition to the 64k main RAM, 1024 half-bytes of color RAM (SRAM).
Now, in reality, thing would have been somewhat make confusing. The 128k REU was the Commodore 1700, the 256k REU was the 1764, and the 512k REU was named 1750. Hm, a smaller number for a larger unit? It becomes a bit clearer when taking into account the the 1700 (128k) and the 1750 (512k) were meant for the C128 and the 1764 (256k) was meant for thee C64 (even though the 1700 and the 1750 worked in the C64 as well). The 2M version of the REU (1750XL) did not come from Commodore, so this is no indication on how Commodore would have named a 16M model. Maybe 1716; they seemed to have wanted to stick with 4 digit product numbers.
Holy shit. I love the demoscene.
Very cool demo!
Amazing ... I'm used ZX Spectrum 128k+AY+FDD. But this is out of mind
Suuuper
great demo
I take it the demo is mostly a full frame video player? Its pretty cool none the less just hard to tell when effects are being rendered or not... of course its mostly obvious when its not ;-)
Yes. Video frames are "streamed" from the REU using DMA.
Amazing !!!!!
Congratulations, magnificent.
Was there ray tracing in that?!?!
it's all pre-rendered images and videos made on another computer, then each video frame is converted to C64 format, and played step by step 25FPS, I am guessing . I don't think they even decompress on the fly (it would take too long)
Cool outro tune
Niesamowite!!!!! To poziom Amigi 500 (a i na tej nie widziałem takich efektów). Mieliśmy z bratem C64 ze stacją przez 2 lata, ale był to przełom lat 80-tych i 90-tych, więc poziom prac scenowych był...hmmmm....przeciętny
So if I understand this correctly, you start the demo up by loading the data from dozens of disks first?
(If the 16MB was all used, uncompressed it takes 97 disks, and well over an hour to load with a fastloader. :D )
Yes. Fortunately, if you use a 1541 Ultimate, you can load the 16MB REU data in less than one minute. Just checked with a 1541 Ultimate II, 25 seconds for the REU, plus 5 seconds for the main program to load, run and finish startup.
O_o WoW!
omfg............!
Is this real thing?
Yes it is a normal c64 machine but with a large extended memory. But calculations and muzaxx are produced by the original chips!
So cool!
So it looks like it was only the memmory thing. If just C64 had more ram then :> How much RAM actually did it extend?
About 16Mb. Obviously, that value don't come from an official REU cartridge from the 80's since the best official one do only 512Kb.
Yes, it's real. Plug a 1541 Ultimate II into your C64 and you can run it on "original hardware". Well - sort of. The largest REU Commodore released was the 1750 with 512kB; Creative Micro Devices released a 1750XL with 2MB. However, the address space, as it was designed, allowed to access 16MB.
Ma moc c64:)
That is 250 times as much memory...
Yeah, such REU wasn't officially released, nor the official ones weren't expandable as the Turbo Chameleon itself (16MB). Impressive demo nonetheless.
This demo would have to have been stored on a format that isn't the floppy disk. Likely a file on a hard drive.
Scanline tricks extend the image palette from 8x8 tiles to 8x1 tiles in 2 colour mode.
Multiple images are used to create pre-rendered images.
3:52 FMV sections stop. Sprites used as scrolling text.
Crest is cheating!
C-64 ? LOL ...
sure... and Im watching this clip on zx spectrum
Learn about the REU, Then come back.
I don't see what's the point - this is not a C64 demo this is a C16000 demo; 250x the ram and something that will never run on a stock C64 or even a C64 with a stock REU. And with that in mind - it's not that pretty and 'just' a fancy videoplayer. Thumbs down.
Most demos are specialist video or animation players, with playback built around the specifics of the 6510 and VIC combination.
Yes agree, thumbs down at you.
The preanimated pictures are not so easy to come up with, the banking business is also a hell of a lot work to get working. Remember that they have to do a lot of precise timing to get things looking as good as it does here. I'm still in awe.
Well, it works on a stock C64 with a stock 1541U2 (of which several thousands have been sold and which is considered an established product).
It could have been done in 1985. The original REU was available with a maximum of 512kB, but hobbyists quickly found out that it was easy to expand these stock REUs to 2MB. There were also third-party REUs with 2MB, some of even used the original MOS 8726 controller chip of the REU. If you insist on "only unmodified original officially supported Commodore components", however, yes, the limit would have been 256kB (yes, the 512kB models worked in the C64, but they were marketed for the C128, not the C64). So, 32 frames of video for the 1764 (64 for the 1750, 256 with the hobbyist expansion)...which still would have been awesome. *Especially in 1985.* You can loop frames back and forth to get a nice long smooth animation loop. You could also have used a letterbox effect to double the number of frames.
What makes this thing worthwhile to watch is that it presents a creative solution to a problem which, well, honestly no one ever had. And which could have been done, realistically, with hardware available in 1990. Only a few years later, PC and Apple users would be excited at seeing a stamp-sized video on their desktops...
Also, the developers with insight into the workings of the C64, can appreciate the technical aspects of the work (and the effort which went into this). The text in the demo already explains a lot of the technical details.

Edit: sorry, my fault - actually, the first demo for the REU came out in 1985 (a monochrome hi-res spinning world globe, programmed by someone at Commodore, for the presentation of the REU at the CES I guess).
