Super Mario Bros Underground - Alternative Soundtrack Music Jam #3 for itch.io submission

The conception of just when this remake is occurring is something like this:  a version of SMB 1 which uses the Lost Levels is needing music in late 1987 or early 1988 so that it's plausible that it has a little bit more complex music than back in 1985.  In other words its like a Lost Levels that is released a few months before the Super Mario Bros 2. that was the Doki Doki Panic conversion (Super Mario Bros USA in Japan).
