About
Pokémon Rejuvenation is a companion fan RPG to Pokémon Reborn, developed by Jan and the Reborn Evolved community at rebornevo.com. It features its own story, region, and characters while sharing the same RPG Maker XP Linux runtime and community infrastructure as Reborn. Free standalone download — no original Pokemon game required. The rebornevo.com Steam Deck setup guide covers both Reborn and Rejuvenation, including the directional input fix that is required on Deck for both games.

⚙ Setup notes
Native Linux — no Proton. The official Linux download (v13.5.x) ships a native MKXP-Z AppImage (mkxp-z.Appimage); add it as a Non-Steam game and run it directly on SteamOS. (The Windows build uses Game.exe + updater.exe and would need Proton, but the Linux build is preferred on Deck.) Gamepad works natively through MKXP-Z; the recommended Steam Input layout maps back-grip buttons (M/turbo, F12 soft-reset, Enter, Shift). Install method: download the Linux zip and extract; in Steam "Add a Non-Steam Game" you may have to type mkxp-z.Appimage manually since the file browser can hide it.
The one thing to know
Native Linux: Use the official Linux download — it runs as a native MKXP-Z AppImage (mkxp-z.Appimage), no Proton needed. Add it as a Non-Steam game.
Add-to-Steam quirk: Steam's file browser may not show the AppImage; type mkxp-z.Appimage manually in the filename field.
Free download: Free standalone from rebornevo.com; no original Pokemon files needed.
Separate game: A separate game from Reborn with its own story and region.
Community guides
Write-ups and threads from people who got this (or a similar) game running. deckport links to them — it doesn't reproduce them.
Get the artwork
deckport never hosts game images. Open this game on SteamGridDB, pick
the cover / hero / logo / icon you like, and drop them into the
game folder under .deckport-art/ before you push it to the
Deck. The importer files them under the right names automatically.
Run it on your Deck
Two files: the one-time importer (deckport.py) in your
Deck's home folder, and this game's install helper. Copy the game
into ~/Games and run the helper with Steam closed — it
writes the recipe (binary, launch options)
and registers the shortcut with artwork.
