Deep Dive: NESmaker Summer Camp ’22
This is a news message more than an insightful post, but it absolutely belongs to the Deep Dive category. Starting on wedNESday, july 6th 2022, Joe Granato (founder and creator of NESmaker) is organizing a five weeks long online boot camp for NESmaker developers, going deeper into Assembly coding then ever. The main topic will be the Empty module, one that has been untouched in tutorials up until now.
Assembly 101: Branches and compares
The Assembly 101 series touches upon the various isntructions that the NES’ 6502 assembler uses. These instructions make up the program language that is Assembly. In this post, we take a look at the various types of branches that exist within Assembly.
Deep Dive: GetActionStep
In the Deep Dive series, we’ll take apart a NESmaker assembly script and see what it does and how it works. In this first episode, we’ll take a look at the GetActionStep macro.
FAQ: What’s a Macro?
NESmaker users probably came across these little helpful bits and pieces of code: macros. What are they and why are they used?
