Please tell me what mistakes I have there. I'm a complete newbie and I don't know much about it.

That is not plugin source code. That is the output from a decompiler. Just find/obtain the original plugin and go from there. Also, you have the file extension twice in the file name, don't do that.

Thank you for your response. But unfortunately, this mod is no longer on the Internet and I had it downloaded a long time ago, but I did not deal with it further. So I can't find the original .sma anymore...
