Newer loaders often double as game loaders (like the mast1c0re USB game loader ), allowing you to run PS2 ISOs directly from a USB drive. Guide: How to Use an ELF Loader (mast1c0re Method)

: Tools like psx_payload_injector on GitHub provide a cleaner, dark-themed interface with drag-and-drop support for both .elf and .bin files. Why ELF Loaders are "Better" Than Standard Payloads

In the early days, most ELF loading relied on the PS4’s web browser (WebKit) vulnerabilities. While this was revolutionary at the time, it was unstable. If the browser crashed—which happened often—the entire homebrew application would crash with it.

Use a tool like Save Wizard (if required for your firmware) to resign the exploit save to your PSN account.

A means a better HEN. A better HEN means a stable console.
