1.0.0 NOW AVAILABLE! (With Desktop App)


What is Project Eris?

Project Eris is the spiritual successor to BleemSync

Project Eris is a fully fledged modification tool for the PlayStation Classic Mini. It allows users to add games, mods and ports whilst also including a large array of extra features and quality of life improvements.

Please note: The desktop app for Project Eris will be made public at version 1.0.0. The inclusion of the desktop app will make replacing internal games on the PlayStation Classic much easier, however the optional facility to backup/replace/restore internal games IS available as of version 0.9.0 but requires an extra manual step. How to video will be out shortly in the interim.

Q. I am getting SUPER weird behaviour when I try to run Project Eris?

A. Lack of power or overloading the front ports will cause 9/10 issues with Project Eris. This is a design issue with the PlayStation Classic and will occur with any modification. To resolve this issue we always recommend a Power Supply of 2amps or more and potentially looking to do the power limiter mod shown here: https://modmyclassic.com/wiki/index.php?title=PlayStation_Classic#USB_Current_Limiting

Q. HELP!!! My PSC does not boot after restore!

A. Overall this should not happen, as there is a verification before a backup gets flashed. However, there still may be some reasons why this may happen:

  • Backup got corrupted
  • Power loss during restore
  • Brown Out of USB drive

If such a case happens but you kept your backup save at another location there is no need to panic! If you don’t have a backup you will need to, at your own risk, find one or ask a friend.

The PSC uses FASTBOOT as a last resort if any backup flashing went wrong. Fastboot needs the raw partition image in order to restore. Therefore you need to do the following steps:

  • Extract your EPBs (LBOOT, LRECOVERY) with a ZIP tool of your choice. It will extract the following files:
    • boot.img (for LBOOT and LRECOVERY)
    • tz.img (for LBOOT and LRECOVERY)
    • rootfs.ext4 (for LBOOT and LRECOVERY)
    • userdata.ext4 (for LBOOT)
  • Open your PSC and connect the two big points above the “LM-11” text with a paperclip
  • Connect the PSC to the USB of your PC
  • Use fastboot to flash the partitions

In Linux/Mac one can use the following shell script if fastboot is in your path:

fastboot flash BOOTIMG1 BOOT/boot.img
fastboot flash TEE1 BOOT/tz.img
fastboot flash ROOTFS1 BOOT/rootfs.ext4
fastboot flash USRDATA BOOT/userdata.ext4
fastboot flash BOOTIMG2 RECOVERY/boot.img
fastboot flash TEE2 RECOVERY/tz.img
fastboot flash ROOTFS2 RECOVERY/rootfs.ext4
dd bs=1 if=/dev/zero of=misc.img count=16
fastboot flash MISC misc.img
fastboot reboot
rm -rf BOOT RECOVERY misc.img


Expand-Archive LBOOT.EPB.zip -DestinationPath "BOOT"
Expand-Archive LRECOVERY.EPB.zip -DestinationPath "RECOVERY"
.\fastboot.exe flash BOOTIMG1 BOOT\boot.img
.\fastboot.exe flash TEE1 BOOT\tz.img
.\fastboot.exe flash ROOTFS1 BOOT\rootfs.ext4
.\fastboot.exe flash USRDATA BOOT\userdata.ext4
.\fastboot.exe flash BOOTIMG2 RECOVERY\boot.img
.\fastboot.exe flash TEE2 RECOVERY\tz.img
.\fastboot.exe flash ROOTFS2 RECOVERY\rootfs.ext4
.\fastboot.exe flash MISC misc.img
.\fastboot.exe reboot
Get-ChildItem "BOOT","RECOVERY" -Recurse | Remove-Item -Recurse "BOOT","RECOVERY"

Hasoon2000’s PSC Recovery Tool Kit

You can also try restoring your system using Hasoon2000’s PSC Recovery Tool Kit.

This tool is used to revert the PlayStation Classic back to it’s original stock sate, no matter how it was modified. Whether you’ve accidently corrupted the system, are having issues or just want to go back to stock firmware, perhaps to sell it, this will do the job easily.

You will need a copy of your LBOOT.EPB and/or LRECOVERY.EPB for this to work. If you don’t have a copy, you can find one online or borrow your friend’s files.

Q. Does this software modify my PS Classic?
A. Yes – This does mean that you have to install a very small payload to your console. However this is completely safe and unless you hooked the PSC to the pc and tried to SSH to it, you wouldn’t know the difference. If you have no USB devices attached with the payload installed, it will boot like stock.
Q. Does this migrate my BleemSync install to Project Eris?
A. Yes – When you first boot, it should migrate all the components that are migrate-able to Project Eris. Some items like old BleemSync launchers are NOT capable of the migrate so some elements will require manual moving afterwards.
Q. What does backup do?
A. Backup will create upgrade packages, containing your partitions. As those upgrade packages will need signatures to get installed, the signatures are created as well and attached to the debug packages. To ensure, one does not accidentally try to restore a backup created from another console, the signature key is again encrypted with a unique key for each console. The backups are created under


There are three kinds of backups:

  • LBOOT.EPB: Backup of the main partition (ROOTFS1), user data partition, kernel partition and trusted zone
  • LRECOVERY.EPB: Backup of the recovery partition (ROOTFS2), recovery kernel and recovery trusted zone
  • LBOOT_KERNEL.EPB: Backup of only the main kernel and the trusted zone

Q. How do I backup?

A. During boot Bleemsync Bootloader will check, if Backups are already present. If not, all backups are created. You can also force creation of a new backup with the following flags:

  • /media/project_eris/flags/BACKUP_MAIN
  • /media/project_eris/flags/BACKUP_RECOVERY
  • /media/project_eris/flags/BACKUP_KERNEL


Q. What does restore do?
A. Restore will restore one of your backups. It uses the built in updater by SONY to do so.

Q. How do I restore?
A. Restore is triggered through the restore flags:

  • /media/bleemsync/flags/RESTORE_MAIN
  • /media/bleemsync/flags/RESTORE_RECOVERY
  • /media/bleemsync/flags/RESTORE_KERNEL

Please note: Restore will apply the complete backup as it is. This means your PSC will be set to the same state as when the backup was created. All your settings, customization and savegames that are on userdata WILL BE LOST.

Q. Power button is not working in RA or ports?
A. This is by design to prevent corruption of data.
Q. What are the SSH login details?
A. HOST: USERNAME: root PASSWORD: Not Required PORT: 22
Q. What are the FTP login details?
A. HOST: USERNAME: root PASSWORD: Not Required PORT: 21
Q. What are the Telnet login details?
A. HOST: USERNAME: root PASSWORD: Not Required PORT: 23
