What's New in RIVALSFPS.GG 5.4.0

RIVALSFPS.GG 5.4.0 came out on October 22, 2026, the same day as a Marvel Rivals update. Fix Mods for Game Update now converts sound-effect, emote, MVP and music mods as well as voice mods, a new Restore Original Sound Mods tool undoes them all at once, and Quality presets and Lights: Reduced work again on the updated game.

The app checks for updates by itself and, by default, installs this one the next time it starts. If you chose Ask before updating in Settings, it shows Update available and Restart & Update installs it. The What's New bell in the titlebar lists the sound mod change, with a button that opens the Mod Manager.

Fix converts more sound mods

5.3.0 brought voice mods back by converting them to play from sound files the game loads at startup. 5.4.0 does the same for the rest of the game's audio:

• Sound effects, such as a hero's ability sounds. Other heroes keep their own.
• Emote and MVP sounds.
• Music, such as the menu and lobby tracks.
• Loose audio files placed in the game's audio folders. Each one replaces every sound that plays that file.

Open the Mod Manager and click Fix on any sound mod marked Outdated, or run Tools > Fix Mods for Game Update to do them all. Mods that 5.3.0 marked Can't update because they changed sound effects or music are checked again after you update. When a run skips some mods, the result lists them grouped by reason. The full walkthrough is in Marvel Rivals sound effect and music mods not working.

This part is still experimental. If a converted mod sounds wrong, make a ticket in our Discord with the mod's name and where you got it.

Restore Original Sound Mods

A new item in the Mod Manager's Tools menu, Restore Original Sound Mods, puts every sound mod Fix converted back to the file it arrived as, in one go. It asks first and lists the mods it will restore. Each mod keeps its on or off switch. If one can't go back, for example because its backup is missing, it is listed with the reason and keeps playing as converted while the rest are restored. Each row's own Restore original link still works for one mod at a time.

Fixes for the October 22 game update

The October 22 Marvel Rivals update changed the map files the app edits for its graphics layers. On 5.3.0 that showed up three ways:

• Launching with a Quality preset stopped with Can't launch with this Quality preset.
• Shadows, Lights and Background in Graphic Pack Settings could go back to Default.
• Lights: Reduced stopped turning the lamps off.

5.4.0 reads the updated maps correctly and rebuilds the affected layers once after you update. If you turned a preset or a setting off to get into a match, turn it back on. The steps are in Can't launch with this Quality preset.

5.4.0 also handles the next update like this one more gently. If a future game update stops the app from building Background and prop shadows, it builds everything else, lets you launch, and the Graphics tab says the two are paused until the next app update.

Smaller fixes

• A sound mod whose download included a text note, such as a build log, next to its audio was not recognized as a sound mod, so it had no row in Sound Mods and Fix skipped it. It is now listed and converted like any other.
• Skin previews for skins you had not previewed before the game update stopped loading. That was fixed on our side the same day, with no app update needed.

The button on the download page fetches the current release from GitHub, and by default the app keeps itself up to date after that.
