Posts: 19/43		 The SPC file format. (There's an error though - there're just two reserved bytes at offset 2Ch, and it doesn't include the extended tags 35h and 36h.)

You might find parts of the SPC's RAM in the ROM, but not the entire file.

And even so, you need to invoke a reupload to the SPC. That, for instance, happens if you start a new game. (If you did everything "right", you'll crash )


Yea yea, I know.
I should've corrected it. But I'm too lazy to edit the post.

But like I said, I seriously doubt you get an exact match for the entire SPC.


Well, it wasn't the entire HEX bunch. Just most of it.

Did you make sure there's no auto-patching being done that might restore the data?

Posts: 166/1040		 So I opened this SPC file of Super Mario Bros. Overworld theme with a HEX editor.

I copied the whole file by "Select all" and "Copy".
Then I opened the SMAS Rom with a Hex editor, and pressed "Command - F" (Find). And pasted the whole shiz in the search string. It found it, yes; so I replaced it with 00 00 00 00 00 etc..
And opened the ROM in an Emulator.
But The music's still there. Why? I Replaced it with 0's, but it still plays loud 'n' clear..

Thanks in advance.
