SA SCM

An scm file is a binary file with certain structure. The common information about what this file is for can be found here. The scm file structure looks like the following:

(02 00 01)h + 32 bit int Jump to second segment
byte Padding (Global vars)             Space for variable saving (02 00 01)h + 32 bit int Jump to third segment byte Segment id 32 bit int                Number of models (model names)             24 byte model names * number of models(model 0 not used) (02 00 01)h + 32 bit int Jump to fourth segment byte Segment id 32 bit int                MAIN size 32 bit int                Largest mission size 32 bit int                Number of missions 32 bit int                Highest number of locals used in mission/external (mission addresses)       32 bit addresses * number of missions (02 00 01)h + 32 bit int Jump to fifth segment byte Segment id 32 bit int                Largest external size 32 bit int                Number of externals (external data):          28 byte external data * number of externals 20 bytes                Name of external 32 bit int              Offset of external 32 bit int              Size of external (02 00 01)h + 32 bit int Jump to sixth segment byte Segment id 32 bit int                (Unused) (02 00 01)h + 32 bit int Jump to seventh segment byte Segment id 32 bit int                Size of global var space 32 bit int                (Unused) (MAIN code) MAIN section, equal to size defined earlier (mission code) The mission data, missions stored at offsets defined earlier
