Re: A small invader "game" to Atari ST.

Hi there;

Despite of working well on Steem and on Real Hardware, the last version of "Invader" has an erratic behavior on Hatari and Steem SSE due to some IKDB emulation issues. So I made a little modification in order to run in all emulators.

A small invader "game" to Atari ST.

Hi there; I used to code in C using Pure C so I decided to learn 68K assembly. I made this prototype of a space invader game in 68K asm. It works in following way: - A small invader appears randomly on the screen. - The invader moves to the left and to the right. - You can move your ship to the left...

Re: Conditions Calls

There isn't in 8086, If you want to do a 'conditional call', you should jump over the call statement when the condition is not true For example if you want to call if Zero: JNZ NoCall CALL CallIfZero NoCall: Thank you, Keith! I thought that was something like that :-P Just ordered your book from Am...

Conditions Calls

Hi there;

In 8086 assembly is there something like Conditions Calls like the good old Z80? Something like call nc, call nz, etc?

Re: What is faster: stack or registers?

Well compatibility settings don't work. Doesn't appear to matter what options I try. Here's the log: STATUS INFO : @ 12:15:34 MSG : Starting Application IN : Initialization STATUS INFO : @ 12:15:36 MSG : Terminating Application IN : Finalization Mmmmm, it seems that compatibility mode isn't so comp...

If you coulnd't run it, check this walkthroughs made by the gammers: Atari - Programmed in C and Assembly : https://www.youtube.com/watch?v=ZmlqMEdeQTY A...

It's a bit old (year 2003), works on Windows 7 but unfortunately It doesn't work on Windows 8 and Windows 10, sorry.
It's another project for me :)

Re: What is faster: stack or registers?

I have no idea. Run tests and see for yourself. What are you writing and what is the intended platform? Hehehe, I'm writing nothing useful, just a simple shooter. I've made a shoot'm'up for Windows, Amiga, Atari and Speccy and now I'm converting it to MS-DOS, VGA and SB using C and assembly for gra...

Re: What is faster: stack or registers?

I did a bit of searching: you should be able to find a copy by typing "helppc abandonware" in Google. Let me know how it turns out, okay? I have downloaded HelpPC 2.10 and in fact I remember using this very useful tool in the early 90s. Good memories :) Well, if I didn't get it wrong and ...
