Verify File Structure

After extraction, your folder should contain:
EssentialsBES/
├── Game.exe              # Main game executable
├── Game.rxproj           # RPG Maker XP project file
├── Editor.exe            # Alternative editor
├── Data/                 # Compiled game data
├── PBS/                  # Editable data files
├── Graphics/             # Sprites and images
├── Audio/                # Music and sounds
├── Tools/                # Development utilities
├── Fonts/                # Game fonts
├── mkxp.json            # MKXP configuration
├── RGSS102E.dll         # Ruby Game Scripting System
└── README.md            # Project information
If you don’t see these files, the archive may not have extracted correctly. Try extracting again.

Configure MKXP (Optional)

Pokémon Essentials BES uses MKXP, a modern implementation of RPG Maker XP’s engine. You can configure it by editing mkxp.json:
mkxp.json
{
  // Enable F12 game reset (currently disabled)
  "enableReset": false,
  
  // MIDI SoundFont for music playback
  "midiSoundFont": "soundfont.sf2",
  
  // Start in fullscreen mode
  // "fullscreen": false,
  
  // Window resolution
  // "defScreenW": 384,
  // "defScreenH": 512
}
Most users can leave the default MKXP configuration as-is. Advanced users can uncomment and modify settings as needed.
