The Castle walkthrough
Finally, after some months of tenacity, patience and thinking, Fabio 
of MSX Solutions has made what seemed impossible at first sight : a 
complete walkthrough of The Castle, released by Ascii in 1986. This 
giant labyrinth full of traps and enemies has no more secrets for 
him ... and for the MSX community ! It's his final gift for 2005 !
Let's hope that in 2006, MSX Solutions will continue on his way to 
help many MSX fans in their favorite games ... and probably a Castle 
Excellent walkthrough is on the to do list :)
