Installation
Close down Creatures.
Unzip anything ending in .spr into /creatures/images.
Unzip .wav files to /creatures/sounds.
Unzip burrows.sfc to /creatures/.
Look for the file world.sfc in your creatures directory. Rename it to albia.sfc.
Make a copy of burrows.sfc.
Rename your copy of burrows.sfc to world.sfc.
Start creatures!
If you wish to play with your norns in albia again, simply rename world.sfc to terra.sfc, and then rename albia.sfc back to world.sfc. Simple!
