How Were NES Games Coded?
The Nintendo Entertainment System (NES) is an iconic gaming console that revolutionized the world of video games. Released in the mid-1980s, it paved the way for numerous classic titles and beloved franchises. As the NES had no built-in programming capabilities, its games had to be hand-coded using an assembly language specific to the console, known as 6502 assembly language.
Original Design and Language
When Nintendo designed the NES, it selected a modified version of the 6502 processor, which was widely used in various consumer electronics devices at that time. The 6502 processor, like most computers, could understand a wide range of commands using a symbolic language, often known as assembly language.
6502 Assembly Language Characteristics
As noted earlier, the 6502 assembly language was relatively simple, with only 53 possible instructions. Its simplicity, however, is where its genius lies. Using one accumulator, two index registers, and a 256-byte stack, coders developed various techniques to exploit the processor’s features. This combination allowed for optimized programming, minimizing memory requirements, and subsequently, optimizing processing speed.
Nintendo’s Contribution and the Birth of NES Game Coding
After the NES design was completed, the first-party developers at Nintendo used this newly designed programming environment to create demos and simple games. Coders and the development teams worked alongside artists, testers, and product specialists to create new games for the platform. Each game was initially assembled by hand on a desk machine with a program called LEM (Low Level Emulation Manager), which linked the object modules from the assembly languages to create executable game programs.
Major Games that Redefined Gaming
These simple yet highly effective 6502-based games played a massive role in Nintendo’s resurgence into the gaming world. Several first-party Nintendo games that solidified this era included:
- Mighty Mouse – Nintendo’s response to Space Invaders.
- Pin-Ball – Introduced with the NES’ launch to generate buzz for the console.
As mentioned earlier, not all games developed in-house at Nintendo, since their partners (Japanese and European) were asked to send their own creations for various reasons:
- Partners in Japan included companies such as Koei, Square Enix, and Square.
- Some smaller Japanese teams like Square started their successful careers making for the Famicom version of Final Fantasy
