Detailed Description

Chunks and fix-ups for TTO/TTD/TTDP savegames.

TTO loader code is based on SVXConverter by Roman Vetter.

Definition in file oldloader_sl.cpp.


Function Documentation

static void FixTTDDepots (  )  [static]

Workaround for SVXConverter bug, depots 252-255 could be invalid

Definition at line 109 of file oldloader_sl.cpp.

References IsHangarTile(), and IsRailDepotTile().

static bool FixTTOEngines (  )  [static]

TTD->TTO remapping of engines; 255 means there is no equivalent. SVXConverter uses (almost) the same table.

TTO->TTD remapping of engines. SVXConverter uses the same table.

Definition at line 345 of file oldloader_sl.cpp.

static byte RemapTTOColour ( byte  tto  )  [inline, static]

Lossy remapping of TTO colours to TTD colours. SVXConverter uses the same conversion.
