There are a maximum of 8 file headers in the ExeFS format, which have the following structure:
There are a maximum of 10 file headers in the ExeFS format. (This maximum number of file headers is disputable, with makerom indicating a maximum of 8 sections and makecia indicating a maximum of 10. From a non-SDK point of view, the ExeFS header format can hold no more than 10 file headers within the currently define size of 0x200 bytes.) The file headers have the following structure:
