Supposed to be the same thing as what you did but sometimes these things can be jank.
I already tried that, but it didn't work.
I found a workaround for this, so, I think, no one has to bother anymore.
I write the txt, and implement it in a test ROM. When added, AMKGUI automatically throws out a SPC file in the corresponding folder. So, I can let that SPC file play in a SPC player on loop and compile a new SPC file, and thanks to this SPC player (the one that gets recommended here the most), the file even gets refreshed when it loops.
I don't know if this is "the intended strat" for AMKGUI, but it works. ^_^
