Accidentally enabled an incompatible mode (e.g., Mode 3 – Unhook syscalls on a game that needs syscalls). Fix: Open the ULCFG editor again and disable all modes. Start with only Mode 6 or none, then re-enable one by one.
The ul.cfg file is a small index that maps the game's original ISO structure to its fragmented, split parts. It tells OPL which ul.XXXXXX. file belongs to which game and how to reassemble them in memory during playback. Without a valid ul.cfg file, OPL will not display any games installed in this format.
If you've manually moved files or have "stray" games not showing up in OPL, you need to edit or rebuild the ul.cfg file. Launch the program on your Windows PC. Select Drive: Choose File > Create game from ISO . ulcfg ps2 editor

Traditionally, users had to manually edit these settings inside OPL for every single game using a controller—a tedious, time-consuming process. Alternatively, text-based configuration files like ul.cfg (used by older tools like USBAdvance/USBLD) stored this data in a rigid format. The ULCFG PS2 Editor bridges the gap, allowing users to manage, patch, and batch-edit these files directly from a PC. Key Features of the ULCFG PS2 Editor
This usually means the file size of ULCFG.BIN changed during saving, breaking the ISO's LBA (Logical Block Addressing) structure. Ensure you use a tool like Apache to replace the file cleanly without altering the overall disc layout.
