Redream Per-Game VMUs for LaunchBox
Created by Saieno - @Lets_All_Game on Twitch and YouTube
What it is
A ready-to-use installer package for enabling per-game Virtual Memory Unit (VMU) save file management in Redream; fully integrated with LaunchBox
Why use it
Redream creates four VMU files, and by default all four are shared across all games. This tool creates a vmu0.bin
dynamically per-game, while leaving vmu1–vmu3
shared and persistent.
This allows each game to have its own memory card (vmu0.bin
), preventing cross-game save data conflicts and minimizing space limitations.
Requirements:
- LaunchBox 13.12+ (must be closed during installation)
- Standalone Redream (latest version)
- Redream configured with automated default settings in Launchbox
- Redream needs to be marked as your 'Default Emulator' for the platform
- More than one Emulator configured within Launchbox
- ROM filenames with single spaces only
- Windows 10/11 (not available on Android)
What it does
-
Installs a dynamic launcher (
DCBoot.bat
) and a minimized shortcut (DCBoot.lnk
) -
Installs a custom AHK script (
LaunchGameRedream.ahk
) for handling VMUs -
Copies a blank
vmu-default.bin
into Redream - Modifies Redream Emulator in LaunchBox to hook into the new launcher
-
Installs a custom LaunchBox plugin (
PerGameVMUName.dll
) for consistent and clean VMU naming
Bonus
- Full uninstaller included — reverts all changes and cleans up
- Everything self-contained, no manual file editing required
-
Installer remembers paths via
settings.conf
for faster reinstalls/uninstalls - VMU files are based on the name within LaunchBox for consistency
-
Share and trade per-game VMUs easily from the Redream
VMU_Games
directory
Before You Install
If you already have save data in vmu0.bin
, consider moving those saves to vmu1
, vmu2
, or vmu3
before installing. After installation, Redream will use a new game-specific VMU as vmu0.bin
for each game. Once a game is launched, you can transfer your old saves from the shared VMUs (vmu1–3
) onto the new per-game VMU within Redream itself.
Known Issues
- Filenames with double spaces will not load properly into Redream. Please use a tool like Bulk Rename Utility to clean up ROM filenames before launching.
- If Redream is the only Emulator configured within LaunchBox, it can cause issues on install.
