Saved games from the Windows version of the game do load, but not entirely correctly: enemies just stand around doing nothing, rails don't zap the player, and generally very little works. The console says:

Can't find proc: DoorTouch@CBaseDoor
Can't find proc: DoorTouch@CBaseDoor
Can't find proc: CallMonsterThink@CBaseMonster
Can't find proc: MonsterUse@CBaseMonster
Can't find proc: RampThink@CAmbientGeneric
Can't find proc: ToggleUse@CAmbientGeneric
Can't find proc: BreakTouch@CBreakable
Can't find proc: RampThink@CAmbientGeneric
...
...for a lot of different "proc"s.
