+# Dogbait
+
+This module provides a thread to trick the namco arcade system 246/256 watchdog, to avoit it from shutting down the machine if security dongle is not connected for some time.
+
+it's main purpose is to prevent the watchdog from shutting down the system. while keeping a safe access to security dongle
+
+## How to use this module in your program
+
+Use `SifLoadStartModule` or `LoadModuleBuffer` directly.
+
+due to the purpose of this module, checking if the module loaded successfully and stayed resident on IOP is important
+
+like this:
+```c
+int ret, id;
+id = LoadModuleBuffer(dogbait_irx, size_dogbait_irx, 0, NULL, &ret);
+if (id<0 || ret == 1) we_have_an_error();
+```
+
+If the module fails to load, please let know the user that the machine will shutdown in a few minutes.
+
+Of course, if your app does not involve access to any memory card/security dongle, then loading the following modules in order and keeping a security dongle plugged will also satisfy the watchdog
+```
+rom0:SIO2MAN
+rom0:MCMAN
+rom0:LED
+rom0:DAEMON
+```
