The other really hard part is knowing what is code and what is raw data. The dissembler can't tell the difference so you have to figure it out as you step through the code. Most large chunks of Data are in their own switched banks in ROM for Game Boy stuff but it's still common to find stuff in between code. Just ask any .gbs/.nsf ripper about their struggles with this. Pic related is a disassembly of X that I've been slowly working on. Everything pictured is what the dissassembler spat out. It's all raw data and not code but the disassembler can't tell so it just interpreted the data as instructions and spat this out.

Figuring out what an individual bit of code isn't the worst if you're used to ASM programming. What's a pain is trying to figure out what it does in context of other subroutines.
