In this installment of the Fantasy Game Console Series (an extension to the 16-Bit Virtual Machine Series), we're creating a game in assembly! Specifically, we're trying to recreate the mechanics of frogger, a classic which should a bunch of interesting challenges and problems to solve.
The fantasy console serves as a very simple model for an emulator of a classic game console like the NES or the GameBoy, only without all the tricky real world details and limitations that come with such systems. It allows us to contextualise all the topics we've been learning about while building the VM, and gain some understanding about how it must have been to be a programmer in the days of true resource constraint!

This mini series is all about binary. Over the course of the series, well be building a library that gives us precise control of every bit and operation.
Youll learn how the logical and arithmetic operations work, how different kinds of numbers are encoded, how to set, clear and toggle bits, and how we can create representations of structured binary data.
1. Bits
2. Operations
3. Unsigned Numbers
4. Addition
5. Zero Extension
6. Twos complement
7. Overflow Addition and Sign Extension
8. Shifting
9. Setting, Clearing, and Toggling Bits
10. Endianness
11. Structures

In this episode we finish up with binary parsing by building (almost) arbitrary precision integer and unsigned integer parsers, as well as a parser for extracting ascii strings.
Apologies for my voice in this one - I recorded at the tail end of a chest infection at 6am and it turns out thats when my voice is at its most Barry White.
=[ ℹ About ℹ ]=
During this series we will develop an understanding of the concept of parsing, and build our own parser combinator system from scratch. The system we build will be capable of parsing both binary and text data. Well make use of both object-oriented and function programming principles to develop an effective and intuitive library.

In this episode the parser combinator system is turned on binary data. We learn how to specify and extract individual bits, Typed Arrays, ArrayBuffers and DataViews, and about important concepts like bit ordering.
