This introduces its own issues, but without namespaces, symbol names end
up repeated and delinking fails. The delinked symbols also end up
without namespaces, introducing yet more problems. This is an
improvement for now, but we'll need proper namespace importing into
Ghidra at some point.
The change in the previous commit was a silly case of not thinking
things through, not realizing that the .data range moved to Core.obj was
nowhere near the beginning of the section as it should be. g_game has
been moved back into Jet2.obj (time will tell if this is correct) and a
missed data strucure at the beginning of .data (where it ought to be)
now makes up Core.obj's .data portion.
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.
