- i mean you always have to double or half both start value and sbc... if not the sin is not clean...

- cool @a8... if done send me the source ;)
it can be adjusted ... tmp1 is the start value. in my case it's $100 and sbc #4
$100 sbc #4 ->64
$c0 sbc #3 -> 48
$80 sbc #2 -> 32
$40 sbc #1 -> 16
other values will not create a clean "sin"... - isokadded on the 2013-11-20 14:02:38

- oh...there is no magic in there... indeed that makes no sense...
seems i didn't see the useless lda sintab,x ;)
but be careful some variables @$40-$50 needs to be 0 maybe on atari8 they aren't 0 ... otherwise you will get wrong results.
on vc20 the system clears some of them and i'm using the $0 ones... - isokadded on the 2013-11-20 10:52:27

tVIsteC 20 ... A 256 byte twister for vc20 with sound
So far i know there is no 256 byte twister on VC20 yet... Hm even no 256 byter ? Strange...Anyway
As you can see looks very like the twistex twister i did for vectrex but the code is quite different. The video setup and drawing is a lot more complicated on VC20. Also the VC20 has a 6502 and vectrex a 6509. 6509 has 16 bit registers quite cool Cpu besides...
For those not having the real machine, you can try Vice emulator with the proper settings (no expansion memory, 5kb of ram) or else it won't run: Settings -> Vic settings
