• run function hash checker on JP version (rev 1) to get file boundaries Both JP (rev 1) and Wii U VC release has identical link order.
• dump m4a tables
• split and disassemble the multi-boot programs

From my observation, a lot of << operations are performed on (possibly) negative integers which is undefined behavior in C (apparently this also includes s8 and s16 because of integer promotion).

This kind of UB should be eliminated as long as multiplication also matches the vanilla assembly code.

I think struct Kirby doesn't contain a union. Basically, it has to be a union if ObjectBase::kirby1 is really of type struct Kirby *, but actually it's likely capable of pointing to different types based on struct ObjectBase (and, it really makes no sense to make the field a union as it's accessed everywhere).

src/bonus.c:298:    obj->base.kirby1 = arg0;
src/object.c:1179:        r4->base.kirby1 = r7->base.base.base.parent; // unknown type
src/object.c:1281:    r12->base.kirby1 = r4->base.base.base.parent; // unknown type
src/blockin.c:41:        arg0->base.kirby1 = sub_0803D368(&arg0->base); // It really returns `struct Kirby *` here. 

Fixing the type is easy so I will wait until more code is decompiled to get it more evident.

1. We should make struct ObjectBase a substruct of struct Object2.
2. Type of field kirby2 in struct Object2 needs to be changed.

sub_0800385C and functions from gUnk_082D8DA4 are taking either struct ObjectBase * or struct Kirby *.

Hey, I'm interested in contributing to this decompilation project. I have been working on decompiling the bronto burt code and am mostly done, but I think having a Discord/other group chat may be helpful to organize.

This was an error on the main branch of agbcc as well, though i believe it was fixed there.

`ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

make: *** [cc1] Error 1

mv: rename gcc_arm/cc1 to agbcc_arm: No such file or directory`

I'm trying to implement a similar gliding logic in my indie game and I wanted to go to the source code itself to see if I could replicate the algorithm.

I'm lost at all the complicated assembly.
