+Loading instructions:
+
+At the prompt, press the following sequence to execute the LOAD "" command: J, Shift+P, Shift+P, Enter
+Enable UI controls (Scroll Lock) and start the tape (F2).
+If the program doesn't start automatically after loading, execute the RUN command by pressing: R, Enter
+
+Notes about the dumps:
+
+Due to the way the ZX81 saves to tape, different recordings of identical data (such as those in both sides of a cassette)
+might be stored along with a few different bytes in them. Additional dumps of the same releases should match those differences.
+TZX files for ZX81 are just the .P dumps with an additional header on top, so they may not be the cleanest format for archival.
+
