Hi, I'm Troy. I started and maintain the sc2kfix plugin and project.
Notepad
1995 load crash bug
It looks like this particular crash is a null pointer dereference caused by trying to retrieve the CSimcityView HWND before the CSimcityView class instance actually exists. I probably won't get around to fixing this one since there's a whole modding framework to be written.
Loading requirements
Intercept at int __thiscall LoadGame(void *this, int *a2, char *Src) -- 0x4025A4 -- and check the extension; jump to 0x4302E0 for .sc2
- Load everything into the structures
- Load pszCityName
- Call void sub_402743(void) -- recalculates border connections, updates power and water consumption, loads bond information, does some pollution modifiers I think?
- Call void sub_402EF5(void) -- updates dwTileCount
- Call void sub_401FFA(void) -- does something with regards to graphs, I think? Needs investigation
- Call void sub_430C00(void) if we need to "uncompress" XLAB -- should only need to be done on manually converted save files
- Return a non-zero from LoadGame intercept
