How to start modding Pokémon Crystal with the pret disassembly?

Begin by following the INSTALL.md for setup, then explore the tutorials on the wiki to learn assembly basics and use the provided symbols and tools. The community Discord offers real-time help for common issues.

Pokémon Crystal disassembly or Pokémon Emerald disassembly for beginners?

Pokémon Crystal disassembly is more mature with extensive documentation, but both require assembly knowledge. Emerald might have more modern tools, but Crystal's accuracy and community support make it a solid choice for focused learning.

Is it legal to use the Pokémon Crystal disassembly for fan games?

The disassembly itself is for educational purposes, but distributing modified ROMs may infringe on Nintendo's copyright. Always check local laws and use it for personal study or non-commercial projects to avoid legal issues.

What tools do I need to compile the Pokémon Crystal disassembly?

You'll need Game Boy-specific assemblers like RGBDS, along with Python for scripts, as outlined in INSTALL.md. The tools repository provides specialized utilities for accurate building and debugging.

Can I port Pokémon Crystal to modern consoles with this disassembly?

While the code is fully available, porting requires significant rewriting for new platforms due to hardware differences. It's primarily for studying or modifying the original Game Boy Color version.

How accurate is the Pokémon Crystal disassembly compared to the original?

It's highly accurate, with SHA-1 verification ensuring byte-perfect ROM builds. The disassembly meticulously preserves all original code and data, making it reliable for preservation and modification.
