+# Daemon (aka: sec_checker)
+
+This module, found on the bootrom of the Arcade PS2s (COH-H models and derivative units) is in charge of checking the security dongle status.
+
+Arcade SYSCON has a 3 to 5 minutes countdown (time may depend on the model) to reset the console.
+
+Arcade Mechacon resets this countdown when the secrAuthDongle routine is successfully completed.
+
+This module setups an IOP thread that calls mcdetectcard2 (DONGLEMAN EXPORT:21) once every minute. effectively keeping the watchdog at bay, but also making access to `mc0:/` rather unstable.
+
+This module is placed here just for hystorical purposes and preservation. there is (as of today) no reason to use a homebrew implementation in favor of `rom0:DAEMON`
