oot3d

A partial Ocarina of Time 3DS Decompilation (Proof of Concept)

Compiler flags (subject to change)

armcc.exe --apcs=/interwork --cpu=MPCore --fpmode=fast --signed_chars --remove_unneeded_entities --split_sections -Otime

--no_autoinline may be desirable while testing snippets of code.

Objdump parameters (via gcc)

objdump.exe -D --demangle -m armv6k func.o > func.s

Notes

• These functions match their original versions, however I have not attempted to link them to the original game's code. As a result, when these functions are compiled on their own, they will have incorrect offsets for functions and global variables. I have decided to ignore these and assume that they would be resolved properly by the linker.
• In order to compile these and generate the correct assembly, you need access to a version of ARM Compiler toolchain 4.1 build 1454 that supports MPCore architecture.
