Kaze no Klonoa: Moonlight Museum
Goal: Beat world 2

Emulator is Oswan and bundled, open the klonoa rom included in the zip.

Controls when horizontal: A (default keyboard C) - grab/throw, B (default keyboard X) jump
Controls when vertical: the third X (default keyboard D) - grab/throw, the second X (default keyboard S) - jump
Start skips cutscenes

What I mean by the above: Wonderswan has a gimmick where games can be played horizontally like a normal handheld, or vertically with the second d-pad doubling as buttons. This game has a few vertical levels where it will swap automatically. You can go ahead and set both of these controls to the same buttons, or just use default keyboard keys.

Keeping pushing A through menus, skip cutscene and when you see the YES stamp with flashing arrows push A on go, end on hitting the goal in 2-6. There are info signs in Japanese everywhere, but the info given is easily figured out. You grab enemies and objects, and can either throw them or double jump with them throwing them downwards. You must collect all 3 stars in each level to complete it, all other collectibles are optional. Blocks way down you and other objects.
