WORDS FROM THE AUTHOR

Having tackled all of the Dylan Dog series, applying what I learned there
to patch Diabolik was straightforward enough. The first episode is very 
similar to Dylan Dog 01, with one slight difference: the game ditches the OS
interrupts for its own - something DD never does - which makes me think it
predates DD1 ever so slightly.

The VertB interrupt in the game also has a problem only seen in the earliest
Dylan Dog game "The Murderers", where address registers a4/a6 are assumed
to be set correctly and will therefore break if a vblank occurs in the
middle of a WHDL function. Naturally this is fixed so it won't break!

You can skip the credits in this one and jump straight to the game, as going
through those every time I tested the game was quite tedious.

I even added some more trainers this time. I should probably go add these
extra features to Dylan Dog at some point...

Greetings and thanks to Denis for the original, and to the folks at the EAB
forums for testing and support.

Enjoy! :-)
