What was once destined for the “not working” pile due to missing data has been revived into a 95% functional game—all thanks to my love for the series.

Luckily, the app uses assets directly pulled from Resident Evil Remake (GameCube), which made the process much more manageable. And that brings us to this release.

Thankfully, the game does include a working map that displays your current section of the mansion—though it doesn’t indicate which frame—so it served as a reference. Over the course of about 30 hours, I rebuilt the entire mansion piece by piece from those black voids.

From there, the most difficult and time-consuming step began: painstakingly reconstructing the mansion, one scene at a time. Essentially, I would enter the game, move around in a pitch-black void (screenshot here), and try to deduce which part of the map I had reached.

The next challenge was that I had no idea what image IDs, patterns, or references the game expected, and much of the code was heavily obfuscated. To work around this, I generated plain black images labeled with ID numbers so I could track exactly which files the game was attempting to load.

I managed to get it running—but the battle wasn’t over yet. The game was unstable, frequently crashing due to missing SD card data. After digging into the code and testing, I discovered the app required “scene files,” which were primarily background images accompanied by text files.

This app turned out to be an SD-related game—at least partially. What makes it unique is that it relies on both the SP and SD cards for storing data. At first, the game refused to even boot due to missing essential files. After some reverse engineering and building a custom server,
