GCW Zero port of Sabre by Artur "zear" Rojek

In order to compile:

cd ./sabre/
make
cd ./sdlsrc/
cp ../src/main.C .
make

GCW Zero release files are in ./opk/

Please note that in order to port Sabre to GCW Zero, input code had to be hacked. Ports to non-handheld platforms should use the original code instead.
