Thank you! The baseball one is a childhood memory from Wario Land 4 (GBA, 2001). It was released a few years before the GBA WarioWare, but the minigame was so fun I like to think it inspired that developer to make WarioWare a few years later. This is the page on it, and I feel silly that I forgot to reference it during the jam: https://www.mariowiki.com/Wario%27s_Homerun_Derby. There's a lot of important details I missed, like the pitcher nodding hints to the player, and the screen becoming lighter after cracking.
