The catalog in 3D
The same catalog has a room you can walk around in. The cat behind the counter is the AI Catbot, and they pick real games from it when you tell them what you feel like playing. Nothing is for sale, here or in there. Go in from here and this game is already out on the counter, with more like it waiting on the shelf next to it.
How it feels
A twisted Undertale-flavored Mario 64 one-level hack flipping the morals of familiar characters into menace.

About
Super Mariofell 64 is a single level rom hack which contains an alternative universe version of The Princess's Secret Slide based on the Undertale AU "Underfell" but applied to Super Mario 64, which inverts the morals of the characters. The rom hack was released by SiIvaGunner during their April Fools' 2026 event, disguised as a playlist link under the video "The Princess's Sinistar Slide - Super Mariofell 64".
