Pros & Cons
Pros
Generates ROMs with matching SHA-1 checksums to the original games, ensuring the disassembly is precise and reliable for preservation.
Provides PlayStation 3 debug versions for enhanced testing and analysis, which is rare in such projects.
Can create Nintendo-compatible patch files (like DMGAAUP0.J56.patch), enabling legal distribution of modifications.
Offers a separate symbols branch for detailed memory mapping, making the assembly code easier to navigate and understand.
Cons
Requires following INSTALL.md and using specific tools from the pret ecosystem, which can be tedious for newcomers.
Relies on Game Boy Color-specific assembly tools that may not integrate with modern IDEs or version control workflows.
Inherently constrained by the Game Boy Color's capabilities, making significant graphical or performance enhancements difficult without extensive hacking.
