What Remains Technical Breakdown
What Remains is a narrative adventure game for the 8-bit NES video game console, and was released in March 2019 as a free ROM, playable in emulator. It was created by a small team, Iodine Dynamics, over the course of two years of on and off development. It’s currently in the hardware phase as a limited batch of cartridges are being created from all recycled parts.
The game plays out over 6 stages, wherein the player walks around multiple scenes with 4-way scrolling maps, speaking to NPCs, collecting clues, learning about their world, playing mini-games, and solving simple puzzles. As the primary engineer on this project, I faced a lot of challenges in bringing the team’s vision to reality. Given the significant restrains of the NES hardware, making any game is difficult enough, let alone one with as much content as What Remains. Only by creating useful subsystems to hide and manage this complexity were we able to work as a team to complete the game.
Herein is a technical breakdown of some of the pieces that make up our game’s engine, in the hopes that others find it useful or at least interesting to read about.
