66.2MB, but there is no sound...
If You have more space, You can copy the comi.la2 from the second CD to Your storage card too (additional 79.5MB - it is needed to play the whole game until it's end).
If You like to have sound (and video), You need to copy the things from the resource-directory too...
To the "anonymous" guy, if You could tell more about the error (e.g. when does it raise), maybe somebody can help You...
And another thing: because this is an english speaking forum, and most of the people doesn't understand german, please translate the error message too!
Greetings, Helge
