Re: Questions about the book
No, the book does not cover game logic or platform specifics. The book is basically 3 examples from the simple series (hello world, Bitmap drawing, bitmap movement) on one platform (The simplest for each cpu), an introduction to the processor, and a description of each instruction in the processor,...

Questions about the book
Hello, I didn't know where else to post this but I'm curious about the book. I hope I don't come across as stupid or asking weird questions. 1. Does the book touch on game logic at all or is it simply an introduction, a taster for ASM programming? 2. What differences does the book have with the writ...

Re: Another rather newbie question
If you didn't understand Keith's explanation I will add a little more to it so maybe you can understand it. To convert a hex value to an ASCII letter first notice that in the ASCII table there is a gap, of size 7,between the two groups of characters 0 to 9 and A to F, this obviously suggest to spli...

Another rather newbie question
Hello. So I'm looking at the hex converter you wrote, and I have two questions: So the division works by loading the register b with 16 (because hex is base 16), subtracting the "main" number with it, and then adding a "tally" by increasing the c register until the register B get...

Re: introducing myself
Hello Martijn! Glad to see a fellow MSX fan onboard. My mom actually owned an MSX1 as a kid herself.
Weirdly, I came here primarily for the MSX.

Looping strings
Hi there, I've wanted to know how to loop strings. I've tried using the register B as what "carries" the loop. I wrote my PrintString correctly, but I have no idea how to make the word "Test" constantly repeating. org &8100 PrintChar equ &BB5A ld hl,Message ld b, 10 call ...

A greeting to you all
Hello, my name is Nephesh. I'm a teenager, but find a strong interest in old hardware and software. I'm from Dubai, UAE. I wish to learn 6502 and Z80 Assembly, and perhaps other architectures like x86 later on. My primary architectures and fields of interest in terms of ASM (i.e. what I want to lear...
