but what you're saying is that CacheCDFS can cope with Joliet/Rockridge ISO standards?
I just changed my CD0: file to use CacheCDFS instead of AmiCDSF and it works!!!
I am doing this in WinUAE (OS3.9 BB2).
if you want to change any setting in cacheCDFS use the program. it's normaly found in Prefs. Do you not have it? do you want it? will it work in an OS not 3.9?
