Technical notes

No BIOS or firmware required. All files listed below are optional runtime data that improve compatibility and audio quality.

RTP (Run-Time Package) contains default assets (sprites, music, sound effects) shared by many RPG Maker games. Games that ship all their own assets do not need it. The RPG Maker 2000 and 2003 RTPs are separate packages. EasyRPG also supports translated/third-party RTP variants (Don Miguel, Kadokawa, Enterbrain, RPG Advocate, etc.) and auto-detects which one a game uses.

For MIDI music, a General MIDI soundfont in SF2 format is needed. Place it as easyrpg.soundfont in the system directory, or put any .sf2 file in easyrpg-player/Soundfont/ and select it from the core settings menu.

4 files | 0 required, 4 optional | 0 in repo, 4 missing | 2 with HLE fallback Categories: 4 game data

`easyrpg.soundfont` -optional, HLE available, game_data, missing from repo

- Source: `decoder_fluidsynth.cpp:125`
- General MIDI soundfont (SF2 format) for MIDI music playback. Many RPG Maker games use MIDI for background music. Without a soundfont, MIDI falls back to the built-in FmMidi synthesizer (lower quality). Any GM-compatible .sf2 works.

`wildmidi.cfg` -optional, HLE available, game_data, missing from repo

- Source: `decoder_wildmidi.cpp:103-104`
- WildMidi configuration file pointing to GUS patch sets for MIDI playback. Alternative to FluidSynth/SF2. Only used if WildMidi support is compiled in and FluidSynth is not available or disabled.

`RPG Maker 2000 RTP` -optional, game_data, directory, missing from repo

- Path: `rtp/2000/`
- Source: `filefinder_rtp.cpp:73-74`
- Run-Time Package for RPG Maker 2000 games. Contains default tilesets, character sprites, battle animations, music, and sound effects. Only needed by games that reference RTP assets instead of bundling them. Multiple RTP variants exist (Japanese official, English official, Don Miguel English translation). EasyRPG auto-detects which variant a game expects.

`RPG Maker 2003 RTP` -optional, game_data, directory, missing from repo

- Path: `rtp/2003/`
- Source: `filefinder_rtp.cpp:73-74`
- Run-Time Package for RPG Maker 2003 games. Same concept as the 2000 RTP but with additional battle system assets for the side-view ATB combat. Multiple variants exist (Japanese official, English official, RPG Advocate English, Vlad Russian, Korean, Traditional Chinese).
