ulmake: A modern command-line tool available on GitHub for managing ul.cfg on Linux or Windows.

Commands: It supports add to register new ISOs, delete to remove game entries and their associated file chunks, and list to view current contents.

App Shortcuts: For managing the "Apps" menu in OPL, you may need to edit conf_apps.cfg or title.cfg instead, which are standard text-based configuration files. PS2 - OPL CFG Editor | PSX-Place
