 Original Repository: https://github.com/maccasoft/z80-apps
 
+In this version some minimal changes were applied:
+* On startup, clearing the screen will be performed by the standard
+  VT100 ``^[2J``.
+* The "arrow symbols" below the playfield are symbolized by <>^v, as
+  the symbols used before actually are control characters that most
+  VT100 terminals do not display.
+* The newer version without the undocumented opcode is used.
+
 ## Commands
 
 Use the arrow keys to move the tiles.
