The Yakuza 1 and 2 rereleases on the Wii U export function symbols,
preserving their names, and some debug data was also available in a PS2
release, providing some struct definitions. These have been used to
rename analogous classes, functions, and member variables to the same
names used by Smilebit, plus a more general imitation of their naming
and typing conventions (i.e. Win32 style).
Ghidra sometimes identifies random numbers as pointers, which trips up
our mangler script when it encounters them as they generally have no
type information. We now use heuristics to ignore such references.
objdiff assumes that all symbols in executable memory sections are code,
which led to misbehaviour due to .rdata and .data being marked as
executable in JSRF. We now set these sections to non-executable in
Ghidra to work around this.
We can now create a fresh Ghidra project, import the JSRF executable
into it, import symbols into it, delink object files from it, and then
decompile with objdiff. Just needs some documentation.
