- OPEN PS2 LOADER - 120 Beta 2241 - https://github.com/ps2-mmce/Open-PS2-Loader/releases
- BOOT.ELF: PS2BBL-MMCE by israpps (9 path version)
- BOOT2.ELF: wLaunchELF EXFAT by israpps (Hold
START + R1during boot for emergency access from mass:/RESCUE.ELF) - OSDMENU.ELF: PS2BBL-OSDMENU linked to OSDMENU by pcm720
- Neutrino: Neutrino by rickgaiser (you must place this on your USB root or MMCE root)
- NHDDL: nhddl for Neutrino by pcm720
- POPSTARTER exFAT USB Drivers: BDM Assault by israpps
- POPSTARTER SMB Modules: SMB POPSTARTER by ShaolinAssassin
- DKWDRV: GitHub Repository
- ESR Launcher (Manual Launch): by HowlingWolfHWC
- SAS-Compliant Installation (PS2 Homebrew Store)
- Custom Icon modifications: by koraxial, NathanNeurotic, Yornn
- SYS-CONF: Contains universal configurations for many applications and exploits.
- BOOT: Contains the heart of UMCS, contains essential ELFs and their local settings.
- B?EXEC-SYSTEM: PS2BBL Exploit relevant to your console(s) region(s).
If all three primary boot options fail:
- Hold
START + R1during boot or reboot of PS2 to launch mass://RESCUE.ELF Recommended to download wLE ISR exFAT and rename to RESCUE.ELF. Place at root of usb stick and insert into PS2 usb port. - Modify launch order or applications via:
mc?:/SYS-CONF/PS2BBL.INImc?:/SYS-CONF/PSXBBL.INI
- Alternative launchers (e.g.,
mass:/XEB+/XEBPLUS.ELF) can be configured to launch using wLaunchELF's built-in text editor. UMCS is designed to be easily configured for custom boot.
- Applications are accessible if installed; however, removing unused applications via the PS2 Browser (Memory Card Icon Screen) is recommended to free space.
- Customize boot preferences by editing:
mc?:/SYS-CONF/PS2BBL.INI - PSX consoles (PSX-DESR) default to launching wLaunchELF (configured via
PSXBBL.INI). - OSDMENU settings (
OSDMENU.CNF) can be customized via wLaunchELF's text editor.
For late-model slim consoles incompatible with standard exploits or if you have a card that is not MagicGate capable, install any update even though it might say incompatible, and then launch the included OpenTuna Icon Installer to gain access to UMCS via OpenTuna. OpenTuna Installer: UMCS is EXTREMELY SLOW! NOT FROZEN! Be patient, its not frozen - it will always throw you an error message if it has a problem. (Which it shouldn't)

Reread the steps, or ask the community — we’re here to help! If KELFBinder is not launching for you, try using a different version of wLaunchELF. If START isn't Booting wLaunchELF, place any program ELF on USB and rename it RESCUE.ELF - this will allow you to launch it when all other options fail by pressing R1 + Start. If KELFBinder won't load on your console, you can use Free McBoot Installer: UMCS for the same installation instead.
