Here are a few recent examples:
Fantasy Zone II for the Mark III
Panorama Cotton for the Mega Drive
Rainbow Islands Extra for the FM Towns
Yume Meikyū Kigurumi Daibōken (aka Dream Maze) for the Super Famicom
I also really want to buy copies of Bubble Bobble for the FM Towns (cover art shown in this recent post) and Puzzle Bobble Mini for the Neo Geo Pocket (cover art shown in this post).
I can't be the only gamers who thinks this way, can I?
