What you can try, and this worked with creatures in my small test, is what has been mentioned before. Download frodo for PC or Mac.
http://frodo.cebix.net/
Then run
frodosc.exe, load up creatures, in the preference section. Run it until you get into the game, meaning the first screen where you control the character, then save a snapshot called
creatures.fss. Load this onto your card and run in FrodoDS. You may need to use 1541 emulation in frodo.fpr(test this in regular
frodo.exe on PC. Remember any game that works in frodo.exe,will work in frodoDS.
You see there are three versions of frodo for PC/Mac. frodopc.exe is perfect cycle and frodosc is single cycle, frodo.exe is fastest but has least compatibility, where perfect is slower with better compatibility. The frodosc.exe/snapshot trick works with a lot of things.
Goodluck
