here we go... seems nearly 5 years now since i read the old stuff...
what i would like to point out:
- illegal opcodes description
- how to use extra ram in 130xe and upgraded machine,
how to bankswitch, etc... all for assembler coders. the best is the detection routine (most demos have...) it really works and tells you how much memory is build in...

i made several intros in the past who used this technique... on 64k machines the intro showed less effects than on upgraded machines... automaticly...

- how to do "HIP", 160x200x30 on standard atari machines without nearly flickering... the real story behind it... how it was found back in 1996 by an accident... (read the FAQ)
- how to adress & detect mouse connected to the atari joystick ports... as amiga & atari st mouses... (amiga should be pc compatible?)
- how to make missles transparent in a gr.9 screen... not so easy...

- music pro tracker XASM replay source code to use MPT music in own productions
- Theta musc pro tracker XASM replay source code to use TMC music in own productions
- how to use flashpack for depacking data on the fly in the production (incl. prepacking...)
- how i made my winning intro "really unreal" from 1997. how the twirling effect is done on 6502... a complete description... ("trainer doc")
hmmm.... other interesting sections:
- programming guideline (how to write code that it will work on 6502 ataris and 65816 upgraded etc...)
- CPU detection routine (6502c, 65c02,65816)
- how to tweak antic to get so called "mode9+" etc... the old way... there are clever ways to do this...but it shows the basic concept...
ok.... and you got some information why i love demos, what productions i have made in the past and some taquart stuff...you got a similar sio2pc software for atari ST and other neat stuff...
and not to forget:
www.s-direktnet.de/homepages/k_nadj/a7800.html my atari7800 homebrew incl. source-codes
seems some nice "unusal" collection...
hve
ps. there was a time as student when i had plenty of time to update my site on a regular basis....
