Functions

	Reads a byte from the buffer and decompress if needed.

bool	LoadChunk (LoadgameState ls, void base, const OldChunks *chunks)
	Loads a chunk from the old savegame.

bool	LoadTTDMain (LoadgameState *ls)

bool	LoadTTOMain (LoadgameState *ls)

uint16_t	ReadUint16 (LoadgameState *ls)

uint32_t	ReadUint32 (LoadgameState *ls)

Enumeration Type Documentation

Enumerator
OC_TTD	chunk is valid ONLY for TTD savegames
OC_TTO	-//- TTO (default is neither of these)
OC_DEREFERENCE_POINTER	Dereference the pointer once before writing to it, so we do not have to use big static arrays.
OC_END	End of the whole chunk, all 32 bits set to zero.
