I've been continuing my fun with Dream Land 2 by compiling prerelease media (https://tcrf.net/Prerelease:Kirby%27s_Dream_Land_2), mainly screenshots from some old mags. One really neat difference I've found is in EGM 66's Shoshinkai coverage for January 1995, where the SGB border used to have completely different artwork for the player characters!
Especially Kirby, look at his face and pose.
