ChibiAkumas ASM Programming Forum

Sure, the real question is is it worth it?

As you said, the market of 'real hardware' people is only going to shrink closer to closer zero over time. and no matter how hard you work or good a game you make, you'll never earn anything from a physical release - so is it even worth bothering to make ...

I've come across these kind of problems on the CPC and MSX, and it's basically trial and error until it works.

You have to read over the technical docs, come up with a hypothesis of what's going wrong, write a new version of the example that 'fixes' that possible problem, and repeat until the ...

Yeah, I'm afraid I don't really care if my examples work on real hardware or not - I'm a hobbyist, and I only ever state they work on emulators.

Testing and debugging for real hardware would take an impossible amount of time (I don't even own real hardware for many of the systems I develop for... I ...

As you said, that's simply how the screen memory of the spectrum is organized. To my knowledge there's no simpler way of calculating a VRAM position on the speccy.

Try writing a routine that slowly fills the spectrum screen one byte at a time, and you'll see how the areas of the screen are ...

Can I ask if you've learned Z80 at this stage?
These tutorials assume you already understand Z80 before you try to get graphics on the screen.

You can see the documentation for this lesson here:

Unfortunately the screen co-ordinates on the ...

Welcome to the forum, and good luck with your assembly programming.

The Index of the Volume 2?
I'm afraid it's Volume 1 that covers the Z80... am I misunderstanding what Index your talking about?

Volume 2 covers the 65816, 6809, ARM Thumb, Risc-V and PDP-11 as per the front cover

Volume 1 covered the Z80, 6502, 68000, 8086 and ARM

that said, The first chapter is ...

If it's literally just the vasm command line your stuck with, maybe this will help?

I'm afraid this isn't something I've done as my knowledge of the Amiga is fairly limited, as my preference is for the Genesis or X68 in the 68000 world.

VASM is just an assembler, so it will only get you to an binary file, you'll need to find something to allow you to 'inject' the final binary into ...

Well thank you for your support! I hope the book lives up to your expectations.

I should have added, if you're using linux, my devtools package works very nicely on a Win 7 , or even Win XP VM.

I've used it on my linux machine from a Win7 VM, and often do so on my main pc (I use a steadystate VM ...
