A secure, ultra-fast, and flawless multi-account switcher and launcher for the PC version of Princess Connect! Re:Dive (DMM version).
- Flawless Swapping (Registry-Only): Snapshots and restores only the Cygames Windows registry subtree (
HKCU\Software\Cygames\PrincessConnectReDive) per account. Shared game assets (manifest.dband the LocalLow asset cache) are account-agnostic and are never copied, so switching accounts does not trigger massive asset re-downloads. - Baseline & Restore-on-Exit: Your pre-launcher account state is captured as a baseline and restored after each launched game session closes. If a previous run was force-killed, the baseline is restored on the next launch (crash recovery).
- Per-Account Anti-Detection: Generates and locks a persistent synthetic hardware identity (
mac_address,hdd_serial,motherboard) for each account. No re-randomization on every run, so DMM's server consistently sees the "same physical computer" for a given account. - Direct Launch: After the registry swap, the game executable is launched directly without opening the DMM Game Player interface, saving time and RAM.
- Auto-Updater (Notify-Only): Checks GitHub Releases for a newer version and notifies you. It opens the release page in your browser and never auto-downloads or auto-installs. Can be disabled in Settings → Advanced.
-
Download the latest installer or portable zip from the Releases page only. Release artifacts are built by GitHub Actions on a version tag, not from a maintainer's machine.
-
Verify the download before running it. Each release attaches
SHA256SUMS.txtand an SBOM (sbom.cdx.json). In PowerShell, from the folder you downloaded into:Get-FileHash -Algorithm SHA256 .\PriconneMultiAccountLauncher-v<version>-setup.exe
Compare the result with the matching line in
SHA256SUMS.txt(also printed in the release notes). If they do not match, stop — do not run the file.SHA256SUMS.txtis kept attached to every past release even after its installer is removed, so you can still check a copy you downloaded months ago. -
Double-click the setup file and follow the installation wizard (or extract the portable zip).
About the SmartScreen warning: the binaries are not code-signed yet (a certificate is a recurring cost for a hobby project), so Windows SmartScreen will warn that the publisher is unknown. That warning is about the absence of a signature, not about detected malware. Choose "More info" → "Run anyway" only after the SHA-256 above matches. If you are not comfortable with that, build from source instead.
- Launch the main program from its desktop shortcut or the install folder.
- Go to the Account tab and import your DMM account. Two methods are available:
- Import from DMM — reads the token from the DMM Game Player you are already logged into on this machine.
- Import from Browser — logs into DMM through your system default browser (the default browser is auto-detected; there is no browser picker).
- Create a launch shortcut for each account you want.
- Double-click a shortcut to play and swap between accounts instantly!
Region note: The DMM build of the game is region-locked to Japan (JP). If you are outside Japan, configure a Japanese proxy under Settings → Advanced before logging in and launching.

- Security issues: do not open a public issue — report privately through GitHub Security Advisories. See SECURITY.md.
- Account suspended, or login/launch broke after a DMM update? Please file a breakage report. This launcher sends no telemetry, so a report is the only way the project learns that something stopped working.
- Contribute: Fork, submit PRs, or check out the code at the main repository HetCreep/PriconneMultiAccountLauncher. See CONTRIBUTING.md.
This project is a fork of fa0311/DMMGamePlayerFastLauncher, which does the hard work of keeping the DMM Game Player integration alive. This fork specialises it for Princess Connect! Re:Dive multi-account use and adds per-account isolation; the DMM session handling it is built on came from upstream. Both are MIT-licensed and the original copyright notice is preserved in LICENSE.
