- int 1c sounds as a really great trick
but unfortunetly int 1c didn’t work for me under FreeDOS
and please notice if the whole bios int 8 code + your int 1c code together doesn't last same long each time when it runs, then the sound quality will be a bit worse. - isokadded on the 2018-10-24 23:27:04
- demo JavaScript Look closer by Ninjadev [web]
- the music wasn't as good as in previous Ninjadev pords, but I really like this kind of zoomer effect.

- demo Windows Extrapurrestrial Impawsibility by Anatomic Kittens
- the sound and the visual didn't work together for me

- demo Windows porter by Top Right Bottom Left [web]
- I really enjoyed.

- @HellMood: only two intros of mine have similar sound to speacore (life&life and teacups). and those kick drums are very sensitive to the speed of the PC :-()
about the pc speaker:
Yes, the default PIT mode#3 is about square wave freqs. But check the PIT mode#0, it is about the PM, you can use it for playing digitized sample. - isokadded on the 2018-10-16 23:31:19

- good sound, nice visual, but i didn't catch what hellmood is talking about... what is new? viznut introduced covox to the sizecoding scene in 2011... in 125 bytes.
and I had several intros with pwm sound in the past two years: plasmifier cover, tctronic, 256unlimited
frag has right, the covox sounds better, beacuse of the 8 bits sample, pc speaker able to do only 6 bits... moreover DOSBox has an annoying repetitive high pitch.
Luckily my HP Desktop has a very good and loud PC speaker, but otherhand it has no parallel port for a covox extension (yes the usb adapters don't work, but i could buy a pci express LPT card for that).
as I heard Kuemmel is also thinking of a sizecoding.org article in this topic... the more articles the better :-)
btw
has I missed provod's stream? where could I rewatch it? - isokadded on the 2018-10-16 20:25:19
- 256b procedural graphics MS-Dos RTX ON by Abaddon [web]
- About this intro I think the most important to show how far we can get with this technique... What is the maximum quality?
I don't agree it is easy to choose the right enhancements. For example with a linear color palette from black to pink or to orange (like palettes in dementia) we would get much poorer result. And now it is also proved, that the two level bluring works well for more details.
After this I don't wanna draw another naked pic, but if anybody want, then there is a pixel editor in the bonus folder. The important thing while drawing use more blocks at the side of lightsource (for example on the right side) than on the other side.
it's possible to draw bigger (wider) picture as well... if the intro don't do anything else just put the pic on the screen then you have more free bytes to store more data. The image intro had 52 bytes data and at the moment rtxon use only 43 and a half (so 44) bytes data for the blocks...
Till now this is the best pic in 256 bytes category (for me).
And I like to read every comment. Thanks :-) - isokadded on the 2018-10-16 19:18:45

- I'm just want to declare that I'm pretty sure the intro runs on every config, all the DOSBoxes, and under any DOS. It starts with a pause effect with black screen so all you need just wait. The lower DOSBox cycles, the more patience needed.
My remote entry was sent in time, days before the deadline, so I wasn't happy to see something else on the stream instead of my real prod. (it was a weaker attempt by me and left it in the archive file as a bonus). But the lesson learned and now I've updated the zip archive with a RUN.BAT file, which contains only two lines: cycles max and rtxon.com.
On Saturday I left the stream immediately after the compo and didn't see the rerun (which was the same from my intros's point of view). Just on the next day I slowly realized how fantastic 256b compo could have been!
Do not misunderstand me, I'm sure next year this compo will be organized perfectly, good luck and peace! - isokadded on the 2018-10-11 09:37:13

- @wbc: worked for me USBboot +FreeDOS +VolkovCommander
But i'm afraid of the intro use the memory very freely. I don't understand it in detail.
@frag: You are right about sound quality... And please do it! Make your final version! I really want to see it :-) - isokadded on the 2018-10-09 14:54:03

- Somehow here is a version which run under real DOS and sounds via PC speaker... @frag: I left 4 NOPs to adjust the colors and the speed of the visuals :)
