When trying to save games there are some things you should take care of:
- make sure the savedisk file is not write protected (when copied from a
CD-ROM to your HD the file ususally is write protected)
- the file must not be compressed (see section about floppy image file
formats); when saving to a compressed image the changes are only saved to
the uncompressed temporary image which becomes deleted when you quit the
emulator
- take care of the compatibility information described in section 1.1; often
savedisk problems go away when using a more compatible setting as disk
access is always a time critical thing
- some games require savedisks to be formatted in a special way; sometimes a
fresh formatted empty AmigaDOS floppy will do, sometimes you have to
create a disk in the game; if possible try using the savedisk that comes
with the game or get a working one
