Z88dk Bank Switching Part 5: SECTIONS

Today, let’s take a look at sections which is a mechanism that Z88dk uses to place bits of code and data within a certain section of memory. This allows Z88dk to manage your memory and automatically make adjustments without having to manually link via code data and code blocks. This is what we need for bank switching.

Data Compression

Our data, i.e. images, sound files, etc need to be compressed if we are going to fit our game within such limited space.

BASIC LOADER

Just about every program written for the ZX Spectrum uses a BASIC loader to perform all the small little steps required to load your game, our program is no different. We have to load our main binary, perform a bank switch and load each of the banks separately. Continue reading “Z88dk Bank Switching Part 2: Basic loader”
