either your file isn't downloadable or this isn't configured to play in browser... :(
Viewing post in One SFX Editor and Music Tracker to Rule Them All comments
Is this before or after you found the page to run it? It isn't meant to be downloadable until after the full C64-inspired fantasy console is released, at which time I'm going to make all the tools open source, but while they have the Patreon link commented out I'm keeping them browser-only. It will be downloadable within the week, though. I'm not sure why this page shows a zip file and a "play in browser" label when it doesn't let you do either from here... adding a link now.
