I have programmed many languages and on PC it's mostly C or C++, C# and so on... But on older computers like the Atari I prefer the 68000 assembler. It's not much different than program in C. C: A = A + 1 ASM ADD #1,D0 C: A = B[10] ASM MOVE 10(a0),d0 It's more or less the same syntax so it's not dif...
I think programming in 68000 assembly is more or less easier or the same difficulty as program in C. The commands are complex and it's so much easier to keep track of memory and time critical things than doing it in C. On a modern computer it's different ofcourse,
What I did in my Giana sisters STE conversion is that when I enter a new level I setup several screens with all the graphics so that the scroll routine only has to do that and not fill in any new data. I tried that at first, but it takes a lot of processor power to redraw the new 16 pixels that will...
I have been using version 3.7.2 for a while without any problems. When I checked I saw that there were newer versions out so I tried the 3.9.0 but found a lot of bugs. I haven't checked with the versions between 3.7.2 - 3.9.0 so can't say were the errors first shows up. some things I found was that:...
but what bout Atari 8bit games enhanced for the ST?
That would be very difficult since it's a different processor. You would need to rewrite the entire game so it would not be an enhanced version but instead a new game.
Does anyone know why it never got finished? What happened to the guy who created it? It seems to be so close to be a final fully working version so had been great if it was finished someday.
Megadrive/Genesis gamepad won't work on a ST cause the extra signals locks up the keyboard, believe me I've tried. Will work if plugged in the mouse port though... strange. I have used it in games. I don't think there are any extra signals from the joystick port that can lock up anything. Only the ...
I see that the sky gradient "jump" one pixel. I guess you create it with a Timer B interrupt that sometimes trigger on the wrong line. One way to get around that problem is to trigger the interrupt one line before and when it trigger, check if you are on that line or on the next one becaus...
If you want to do regular flat shaded polygons, then C2P is not necessary. You can do that rather fast in the normal bitplane mode. C2P is rather costly and it's only with texture mapping you might want to use it.
In some occasions one frame can take longer than one VBI so I guess this is what cause the problem. It shouldn't happen so often and I can't really fix it either since the game take 100% CPU if all sprites are on screen at once.
Made a quick video just now comparing to the original. Once again I must say this is great work, really appreciate playing a nice version on the STE! I see you run the 2013 version. The one I made 2015 also got shadows included. I was playing for a little bit when I got a weird graphical glitch whi...
Sorry to hear that :-/ I always hated flashing things - PC BIOS, routers... anything. Bad for blood pressure. :) Yes but I like to get the newest firmware on stuff if it's a bit old. Mine on CosmosEX was since 2014 and I saw there were a lot of newer ones. I just followed the instructions and I got...
Yes since I had my STE up and running (was a while ago since last time) I decided to update the CosmosEX and it seems like now it's totally messed up . I guess I have to reinstall it from scratch.
With the latest build I can see the splash screens but they are not steady (like if the horizontal sync is messed up) and the monitor shows "no signal" for a second but then the image comes back again. This is an old TV I have hooked up. I will try with a dedicated CRT monitor as well.
When I deleted the PCD files the game started and that worked! It looks great on a CRT monitor. There is flicker but you can't see the individual frames so it looks like more colors. To bad I can't see the intro images.
Now it started but doesn't work. It shows for a couple of seconds some blue lines on the screen and after that the CRT monitor shows "no signal". It works under STEEM without any problems.
I can't get it to work. I press DEMO1.TOS and after a few seconds it returns to desktop. I can see it writes out something unknown.... but since it return immediately I can't see what else it says. I tried it on both low and medium res. It's a 4Mb normal STE machine. I tried it both from the USB mem...
