Reliqui Studio

All-in-one editor for Pokémon Essentials fangames, free.

I started my fangame over 10 years ago in RPG Maker XP, picked it back up this year, and got so frustrated going back to the same old tools (Notepad for the PBS files, a map editor from 2004…) that I built my own: an all-in-one editor for Pokémon Essentials where you never touch RPG Maker at all.

WHAT IT REPLACES

Before: PBS files by hand in Notepad → Now: visual editors for Pokédex, types, encounters, items, moves, trainers

Before: RMXP's map editor, 3 layers, no reliable undo → Now: up to 8 layers, undo, paint bucket, copy/paste regions, autotiles with automatic borders

Before: map connections typed into a text file → Now: a visual canvas — drag maps around, snap them edge to edge, connections write themselves

Before: events through the RMXP editor → Now: full event editor + 1-click recipes (NPC, sign, shop, nurse, trainer, teleport, harbor)

Before: no version control → Now: built-in Git, one-click "Save version" plus automatic backups before every save

Before: sharing your game means exposing the whole folder → Now: encrypted export (RGSSAD) + installer generator

STANDOUT FEATURES

Multiple shiny variants per species, each with its own conditions (weather, time of day, season, switches, level range) or manual activation for gifts and bosses — plus a built-in palette editor that recolors front/back/icon/walking sprites at once, no drawing required.

Custom alternate forms & regional variants (new in 1.1.0): give any species its own forms — types, stats, abilities, movesets, size — with their own sprites, and mark which maps spawn wild Pokémon already wearing the form.

Battle mechanics toggles: turn Mega Evolution, Z-Moves, Dynamax or Terastallization off for your whole game with one checkbox.

Level scaling, Gen 5 seasons, inter-region travel, a fakemon wizard, a move-effect picker searchable in plain language (457 effects), damage/balance calculator, project notes, safe autosave, and a Play button that compiles and launches your game instantly.

UNDER THE HOOD

A desktop app that edits the real files of your Essentials project — no proprietary formats. Byte-for-byte verified writing of .rxdata files, automatic rotating backups before every save, multi-project support (imports Essentials v9–v18, reads modern v19–v21 too). If you ever want to go back to RMXP, your project stays 100% compatible.

Interface available in 6 languages: English, Spanish, German, French, Portuguese, Italian. Windows 10/11, 64-bit, no admin rights needed.
