Is 'smkmusic' an editor? I've tried googling it and can't find a link.
I looked at your post history and saw you posted in a recent thread in which someone linked you do this: http://www.smwiki.net/wiki/Addmusic
Is this the tool you're referring to? If so, which? (there are 3 mentioned on that page)
PS: I shouldn't have to find these links on my own. Please make some effort into providing details and links so I don't have to guess at what I think you mean.
Let's put this more simply:
1) Give me links to any tools you're using
2) Tell me what you actually did with them to get the "side by side config" error message. A step-by-step outline would be great
3) Tell me anything else you tried
Here's a recent post I made on another forum where I was asking a question about their specific toolkit:https://forums.wxwidgets.org/viewtopic.php?f=1&t=42342
Notice how I span 3 paragraphs telling them what I want, what I'm doing, what I tried, and finally asking if there's a different solution I can take.
Contrast that to your 1-sentence replies where you are vague and don't give any real info.
I don't mean to be an asshole about this -- but learning how to ask a question properly will do wonders for you. ESPECIALLY
in technical areas like ROM hacking.
