So if i understand you correctly i don't need to install the database right? WebMan Mod just comes with it?
The PS2CONFIG database is only needed for encrypted ISO (BIN.ENC) which can be used on CFW and required for HEN.
For non-encrypted PS2 ISO (CFW only), webMAN MOD already comes with the config files.
The online updater available in webMAN Setup menu of keeps the PS2 config database up-to-date with the latest additions.
