Re: 256 Byte Boundary

"bad screen address" is normally as the memory bank hasn't been reserved as screen. reserve as screen 10 logic=start(10) I have done a scroller based on a 64K screen but its been some 20 years.. I think you would reserve a work bank (or data bank) and load in pi1 images, so first image lo...

Re: 256 Byte Boundary

Hi, If you are using STOS, I imagine that it is on a ST/E. So the screen uses 32k. Are you sure that start+X+32k fits all in memory? Maybe it's not the starting address that is a problem, but indirectly the end address that bypasses the top of RAM. Guillaume. Hi - definitely an STFM, using 2.6 of S...

Re: 256 Byte Boundary

1) How are you trying to set it? If using XBIOS SetScreen() function, note that it is a VOID function that doesn't return a value. 2) Where you getting "error 43" and how are you interpreting that as "bad screen address". All regular system error codes are negative, so that soun...

256 Byte Boundary

Hi, just a quick question. I'm trying to set "logic" to be a particular address. I know the address is on a 256 byte boundary (as per what it says in the manual). However, when I try and set it I get error 43, which is "bad screen address". This doesn't make sense as the address ...

Re: Code:BLACK - A New DEMO in STOS

Hi, cool you've released something. Just trying it out. What machine does it run on? The music starts and I get the initial credits, but the screen goes white, the music keeps playing and I don't see anything. Is my bog-standard 520STFM not enough? Thanks, M.

Re: Missing Link docs?

As far as WORLD for scrolltext goes, Are you not using the MAP/WORLD system in conjunction with each other? i.e using sprites that are converted to maps blocks and then using WORLD? There is a program called MAKE that converts between the differing file formats and I also recommend EDDIE Program in...

Re: STOS Parallax, SKOPY and the 4 bitplanes Using MISTY

Well, this isn't quite finished, but you get the idea for this screen - four demos, one in each corner of the screen (barrel scroller, starfield, VU bars, scrolltext). Got to finalise the colours, improve the presentation a bit, change the scrolltext font and add rasters. That's the intention, anywa...

I'm glad to say I've cracked it. :) I went back to Exxos's STOS resources site, where there's a single "BitCopy" archive. The document that's in the archive is a little more helpful and explains about copying a single bitplane when it's not number one (i.e moving just plane 4). So, I wasn'...

I'm going to post this here, mainly because it explained the whole bitplanes thing better than anything else I've read so far: http://mikro.naprvyraz.sk/docs/Coding/Atari/Maggie/STDEMO2.TXT In essence, plane one is under plane two, which is under plane three then four.

Re: STOS Parallax, SKOPY and the 4 bitplanes Using MISTY

I was going to ask about this, too. I seem to be able to move bits around without issue using skopy, as long as there's "clear space" around. The colour of what I'm moving (on a single bitplane) seems correct, but as soon as what I'm moving comes into contact with something of another colo...

Re: The RUN command.

I've just had a look at Flair's "Cunning Demo". I think they cheated a bit, because they created something called "LOADER.PRG" in the Auto folder. It's only 6K, so there's absolutely no way it's a STOS program (even if they used a packer on it). They must've created a loader in d...

As there is a SND archive, I assume that routine plays the files also listed on my site ? I'm not sure, but I ended up downloading the full archive at http://sndh.atari.org/ (plus an appropriate Mac player to listen). I tried one file and it seemed to work. Will let you know how I get on.
