This directory contains the source for the MorphOS port of ScummVM. To build, you
|
||||
must have a proper Geek Gadgets installation. Just type "make" in the MorphOS
|
||||
subdirectory. If you don't have the includes for AMidi 2 and cdda.library, check
|
||||
my webpage. If they aren't uploaded yet, feel free to e-mail me.
|
||||
|
||||
You don't have to build ScummVM yourself. The latest official and CVS binaries are
|
||||
available from my website at:
