Two weeks ago Infinite's game Montana John and the Templar's Treasure was released. Today a patch was released which allows you to enter the password by simply typing in with the keyboard. All of the selectable characters and commands are now mapped to keys on the keyboard and should be self-explanatory. The ones that might not be so clear are:
"<" and ">" which are mapped to the "<" and ">" keys (not the cursor keys). Also "<" is mapped to the BS key.

The IPS patch is available in the MSX IPS Patch Archive.
