 In terms of adding objects, you&#39;d probably have to do that in hex.<br>To use that with, say, SonED, I suggest you do the following:<br>1. Create dummy copy of your ROM.<br>2. Use a level object set that has more objects than your current level (I don&#39;t know which level has the most, so I can&#39;t help you there).<br>3. Edit objects.<br>4. Back-up real ROM.<br>5. Copy object data from dummy ROM to original (place at an &quot;empty&quot; spot in the ROM) ; ESEII should give you the location in hex.<br>6. Change the offset for the level object data for the level you want the new objects for (there are guides out there that show you how to do this).<br>7. Thank me.
