New (Old) 3D Golf: Porting PC-9801 and Virtual Boy to Mega Drive

A developer reverse-engineered T&E SOFT's New 3D Golf Simulation games to extract and modify course data across multiple platforms, discovering that the same course format was used consistently from PC-9801 through Mega Drive and Virtual Boy versions. They successfully ported previously unavailable courses from PC-9801 and Virtual Boy to the Mega Drive, and even created a browser-based 3D golf viewer using the extracted terrain data. The project involved debugging techniques like writing values directly to the cartridge's save memory and implementing custom tools to convert course data between different platform formats.
