New (Old) 3D Golf: Porting PC-9801 and Virtual Boy to Mega Drive
TL;DR
A gap existed in understanding and modifying the terrain data of classic golf games on the Mega Drive. Using reverse engineering techniques and Three.js, a 3D golf game viewer was created, allowing for custom terrain modifications.
✦ Why It Matters
Engineers can learn effective reverse engineering techniques to modernize and enhance legacy software applications.
Key Takeaways
- Explore reverse engineering for legacy software.
- Utilize Three.js for 3D visualizations.
- Implement custom user interfaces in retro games.
- Debug memory issues through manual manipulation.
Full Summary
T&E Soft's New 3D Golf Simulation series for the Mega Drive has long been a favorite among golf game enthusiasts. The project began with extracting course data from the game and visualizing it using Three.js, a JavaScript library for 3D graphics.
By analyzing the data structure, which included 18 holes and approximately 256 points per hole, the developer was able to implement a viewer that resembled a 3D golf game. Challenges included debugging issues caused by uninitialized memory, which were resolved through manual memory manipulation.
The developer also created a new user interface to enhance the gaming experience. The results included successful terrain modifications, such as flattening the course and creating a 'Hyperactive Terrain Mode' that distorted fairways.
This work not only revitalizes a classic game but also provides insights into reverse engineering and game development techniques.
