greatest achievement on limited machines (?)
category: general [glöplog]
And did anyone actually claim otherwise?
I was distracted by the sentence "bah, 2k is the proper size, not 16k"
I'd tend to agree with Gasman about ZX Spectrum examples.
of course there can be much much more of them however seems like we got used to all that incredible stuff like over 100 colours, fully digital 3chnlz songs within 48Kb of RAM and all the other stuff.
But yes, breaking screen-borders in every possible angle was something I remembered. The same goes to SidSound (shamefully untapped).
If I recall anything more, I'll write.

Actually I found something surely memorable.
Seems like we got bored for years with watching movies on ZX Spectrum.
So in 2008 a guy made the Spectrum stream movie from cassette in a software way.
(The first half is the tek blah, the second part is the effect istelf).
Yes. James Bond from tape.
So that's the example from me.

Well, to sum things up:
On 8 bit machines in general:(this is also meant for things yet to do)
-changing the colormap in the border in time to achieve more colors displayed
-clever use of the character mode to achieve fast fullscreen effects
-changes in the sprite registers in the border or during screens to display more sprites at once
-changing the bitmap locyation during the screen display to create animations
-changing the bitmap or character base address to achieve scrolling without hardware scrolling capabilities
-achieving raycasting at a decent speed which was only thought possible to work on 32bit computers before. ;-)
on the AY soundchip:
-less cpu usage
-more clever tricks with the hard envelope registers
-BASS
on z80 machines:
-generate fast code
-use of the 2nd register set
-finding any use for the iX/iY - HL swap
on atari 8bit:
-finding the "truecolor mode" althrough i still hate those blank lines inbetween
-the making of g2F to show that the atari 8bit is capable of more than 4 colors in a scanline
on the C128:
-finding some nice use of the color palette swap of the Vic
in the Vic20:
-the recent find and use of the multicolor mode and other ram realted tricks
-finding other waveforms that can be used for "music" through testing registers said to produce noises
on the cpc:
-smooth scrolling by changing synch registers
-that register that turns off graphics during graphics that can be used for "cut out" effects in bitmaps
-changing the bitmap base address during the display of the bitmap to achieve multiplexing small graphics without having a character mode
-fast fullscreen effects in general
on the plus/4:
-having decent music
-opening the sideborder (just a bit)
-using own graphics and not just ripped ones. ;-)
on the oric, KC85, ZX81:
-achieving any demo effect at all

Many of the tricks you listed are actually quite trivial, some of them even officially documented :(
So what keeps you from doing a raycaster on Vic 20 then? :D
Well I think this prod for the Atari STe ought to get a mention :-)

Exin: he already did: http://pouet.net/prod.php?which=7121
Also this one:
http://www.pouet.net/prod.php?which=52337
It explains the background of the limit being broken very nicely by itself ...

Perhaps not very technically oriented but indeed an achievement, there was some guy in eastern Europe who used a spectrum clone (or something similar) during the 80s to disrupt propaganda television broadcasts and overlay his own text messages. There was an article about it, but I can't find it any more since I don't remember the details clearly enough. Anyone?
Visy: That and raycasting? Yeah right. ;-)
the C64 has almost started a Global Thermonuclear War once! A killer effect!
linde: Telewizja Solidarność. The articles linked there aren't the one I remember reading, but that should give you something to google on...
