De gustibus non est disputandum: some people like to wiggle their joystick to enter a password, others prefer to use the keyboard.
Infinite implemented the former in the original version of
Montana John and the Templar's Treasure and it didn't take long before an
IPS patch became available to accommodate for the latter. Now, with the release of
MJTT 1.1, the IPS patch for keyboard based password entry is also updated. After applying
this patch, you can just type in your password in the password screen.
