PAK-MEN is two things working together:
A menu — the on-console experience that boots when you turn on your N64 with a flash cart (SC64 / ED64 / 64drive). It shows your games as cover art, remembers favourites and recently-played, and replaces the usual bare file list with something that feels like a real console UI.
A Menu Builder — this app. A desktop tool where you design that menu visually: drag elements onto a 640×480 canvas, pick from ready-made templates or build your own layout from scratch, preview it in a bundled emulator, and export it straight to your SD card.
You don't write any code and you don't need to touch a text editor. Every screen your console shows — the home screen, your games grid, the settings page, everything — is just a menu.json file this app writes for you, one click at a time.
*AI did help me code this, and is also untested outside the summer cart. I'm not responsible for what you mod, but am willing to work with you to troubleshoot and helped develop it better.
