Known Errors
     Bugfix provided by Battle Bunny (JimG):
  • There are some adjacent screens where the exit positions don't properly match, so it's possible to move into a wall on the next screen. When it happens, the player bounces off the wall and usually goes back to the previous location. However, there are a few cases where the game doesn't calculate the returning position properly, so the player is bounced around a few times and may arrive at an entirely different location, sometimes outside the map. This problem happens because the game uses a complicated formula for calculating connections between map segments based upon which keys had been pressed, which doesn't work properly if the player moved in diagonal. The correction ignores this calculation and instead saves the current and previous segment addresses, as bouncing back off a wall should always go back to where it just came from regardless of which keys were pressed. Fixed using the following patch:
