I actually agree, I used it for everything! I miss spoke and I really should have said in "some very specific cases" and not "often", that was unfair on my part.

Also, just remembered I also cheated on the blitter by writing longs to loading multiple Blitter registers at once as opposed to multiple byte loads.

I am having second thoughts about my Blitter routine for mixing two samples (one left and one right), it worked in my head but not sure I got working in practice. I am sure it I used clever X inc and Y inc values to rotate the copy (Y as negative) back to the start of the buffer, each sample had to ...

Okay catching up on this thread. I have a few ideas which may be of help but I MUST point out it has been 25 years since I programed on my STE. Also, I only used a little ASM and STOS, however, cheats are cheats in any language. Anything here may well be wrong so do not blast me for it... With the B...

I suspect it was for a demo which is why this question it is here but what was the first MOD engine, when was it made and by whom, etc.

I am looking for a music demo/compo which came out in 20 odd years ago. It had a number of tunes and the main screen had rotating fire spouts running around it. that is all I can remember.

Can anyone name some games that use mixed screen resolution (i.e. low for images, med for high score). I know of none and when I searched I could only find this;

He even did a little blog on how here http://guidohenkel.com/2018/09/the-thin ... -atari-st/

Thanks

Maybe Stardust, I got a demo on a cover disk from memory, bright graphics and heavy "rave" music.

Just in case anyone is interested (and so I can find again).

Sorry quality is not fab, manual grab of song from demo using emulator then conversion to mp3 at 64kb so not too large to upload to here.

Yep the visualizer was fun, as was the tune.

Music reminds me of Clax title music. Looks great...

Does Speedball 2 (Manager Game) count, we used to gather round with pizza and beer and shout at the guy with the joystick to make changes, great fun.

Strider you got it (years ago), it was NTM demo (I found it here https://www.exxoshost.co.uk/atari/games/mega-demos/page8.htm). The specific screen I was on about is the first "Demo Tile" with "Zuul Disk 2" written on it, the screen itself has three pink/yellow Zuul logos bopping about, vertical scr...

I wanted to do this on the STE using the blitter to write the pallet each 16 pixels but the people here showed me that it was just too slow.

Okay imagine your bitmap screen, every line is the same (very important). EVERY LINE is built up from left to right of colour 0 for 64 pixels -> 1, 2, 3, 4....FD, FE, FF then 1, 2, 3, 4.....FD, FE, FF colour 0 for 64 pixels Your change the pallet at the start of each scan line, then you change again...

Okay that came out crap on the forum.

Okay I think my idea if not exactly what you are trying to do but it may be an alternative solution. Okay for each scan line you have bitmap image, every line is the same in video ram; Your bitmap image on screen. Left Border Colour 0 for 64px then bitmap colours Mid Screen Second Pallet right blank...

They are great, very retro in that they don't use any modern sounds effects. They remind me of RanaRama which I loved. Great stuff. I will add that I will assume these tunes would have gone down well for the conservative use of CPU too due to their style. I would have been happy to have any of these...

I am not sure what you are trying to achieve, I assume a 4096 colours per/every other scan line OR 256 px scan line with 256 colours (technically 255 as you will probably want colour zero to be black or white). I may be way off here (been a long day plus wine and not sure on TT colour modes) but cou...

I am just wondering, is it possible to add another device to the Microwire Interface on the STE? I am not sure what and whatever it did would be slow but I was thinking NVRAM (not sure for what), RT Clock or other similar.

Ohhhhhh like that idea...

I cannot find any documentation with regards the potentiometer rating required on the x/y axis. The fire buttons are just mapped as is I assume! The spare can just be mapped to the up and down of joy 2 maybe. I have the feeling that this would work BUT results may be wired as the STE port is multipl...

Hi all, I am wonder has any actually tried just to wire up a (now old) Game Port joystick to the STE Enhanced ports? It seems the wiring is all there, I am interested in the Analogue port (not D pad stuff); Analogue Joystick https://en.wikipedia.org/wiki/Game_port STE Enhanced Ports https://gamesx.c...

You are using an STE, why not use the Blitter to do the sprites? Source and Dest X and Y increments sort out all of these problems plus you do not need to pre-shift. I think you have to do bitplane at a time and SKEW it, I can't remember. Anyone know of example source code to do this? You should be ...
