Each object have the following structure starting from its matching object content offset: | |||
<table border="2" cellspacing="0" cellpadding="4"> | |||
<tr><th>Location</th><th>Format</th><th>Data</th></tr> | |||

<tr><td>0x0e</td><td>UInt8</td><td>Offset to object name</td></tr> | |||
</table> | |||
The object name starts at specified offset. Each character is added to the buffer until a 0x00 value is found. | |||
