So far the Humongous Entertaiment games need the following file operations:
Read from files
Seek in files (Opcode still incomplete)
Write to files
Close files
Delete files
Rename files

The original versions created a temporary save game (temp.sgs through
o6_roomOps case 221) before showing the save game screen and renamed this
temporary saved game when the user makes an actual save of game.
The original versions also checked if a tempoaray file exists sometimes, and
deletes that temporary file if found.
