Orb MegaDemo DELUX VIC20 demo (no memory expansion) at Sundown 2007 September 08 updated 2016 February 02 4Mat, Ultra, Keops ---------------------------- If using VICE emulator: Settings -> Vic settings -> no memory expansion -> Activate true aspect ratio in video settings ---------------------------- http://orb.ultrafex.de Starting: -------- The demo comes with two different starters on disk: "omd.full" Shows all effects old and new... So if you have some time left start this one. Runtime is almost 16 minutes... "omd.new.parts" If you fed up with the old effects you can run this one. Shows only the new effects. Except of intro and endpart. Runtime is almost 10 minutes... Compatiblity ------------ Does not work on 1540, 1581 and SD2IEC (i guess). These users have to use the old version. Tested on real hardware and seemed to work so far... Note: ----- Do you know this? Things you always wanted to code but you never managed? Because of different reasons like: -no time -not at the top of the prio list -job -or too lazy? Back when I (ultra) was 13 fast- and irq loaders on C64 popped up and I was totally fascinated of this stuff. Till then I only did a few intros.. And I said to myself: One day... I will code my own fastloader. And just 31 years later... I finally did it :) In 2007 I did a 1541 emulation on a pic32 controller just to get into the entire theme. So it was a logical consequence to write an own fastloader. The fastloader is done since 7 or 8 years but I wanted to fastload our vc20 demo "omd" and that was a real problem since there isn't enough memory left to hold the fast- loader in memory. So the entire project went to sleep for some years but one day I had the idea. Why not download the fastloader code from floppy memory before?... So I did... The download needs 28 bytes in memory this is even smaller than the old loader ;) New Features: ------------- -Fastloader: On the fly GCR decode (can be done faster I know was enough for the vc20) -5 new 4mat tunes -6 new screens -two new effects from 4mat -the end part has been totally rewritten by 4mat -three new effects from ultra -All screens of ultra have been reworked to fade out clean -Some of the screens got a facelift -Samples and replay in the checkboard zoomer was updated. we recognised it's almost not hearable on real hardware. -Fixed bugs In two screens we are using the unconnected ram feature first used by viznut... Thanks: ------- -must go to Viznut to his waves and unconnected ram stuff. -Krill I borrowed his head moving routine...I'll write one soon ;) Links: ----- http://www.pouet.net/prod.php?which=32034 http://demozoo.org/productions/9193/ https://youtu.be/WlralRNCQR4 http://orb.ultrafex.de Cheers Ultra
