Writeup discussing when to use RGBDS or GBDK.

In the past few years, it seems that, as retro gaming has grown in popularity, programming for older platforms has also gained traction. A popular platform is the Game Boy, both for its nostalgia and (relative) ease to program for.

When someone wants to make their own game, one of the first problems they will encounter is picking the tools they will use. There are two main options: either use GBDK (Game Boy Development Kit) and the language C, or RGBDS (Rednex Game Boy Development System) and the Game Boy's assembly language.

The purpose of this document is to provide my insights and experience, and help you make the better choice if you're starting a new project. I will also provide some "good practice" tips, both for C and ASM, if you have already made up your mind or are already using one of these.

Overview
