Re: Super Mario Bros. 2/The Lost levels
Because Vimm's Lair usually only has American games, and the Famicom version of Super Mario Bros. 2 (aka The Lost Levels) was only released in Japan, it only came to America and Europe as part of the SNES Super Mario All-Stars compilation.
In any case, all Famicom games are on archive.org: https://archive.org/download/nointro.fds
And here's the link to Super Mario Bros 2.
The original Famicom Disk System game never got here for some reason.
