I just downloaded The Super Mario bros. Relocaverburator from the Utilities section and I gotta say, it's pretty easy to use. It's like SMB Utility except more user-friendly and with more features. A few of these features seem to include adding objects and sprites(Obj:40000 and Spr:14000 respectively), but when I click on either one, it gives me "New Object/Sprite(1st Quest) Offset? Add Prefix &H for HEX". I'm a beginner to this kind of thing and understanding how to do this would help me a great deal with making levels! I'll check back when this thread gets a reply.
Thanks in advance to anyone who replies with answers.
