Generally the information in fx legacy: eactivityformat applies to the fxCG-EACT, too.
1. two bytes in the StandardHeader at offset 0x1C are not constant. Possibly some controlbytes; not heeded for by fxCG OS 1.04
2. the size of the setup-directory;
3. the termination of the LineDescriptor array;
4. of course there may be additional EntryTypes.
EACT (only the differeces to fx legacy: eactivityformat):
|Offset (b)||Size (b)||Description|
|0x58+LS+4*LC||4||length2 (filesize - 0x54 - LS)|
