why do you want to do this anyway? i have no experience with a120.
also, if your image is actually large enough to normally fill the disc, then you will NOT be able to fit it onto a cd as a normal data file because a cd/dvd image contains raw sectors, whereas a data cd/dvd only contains the binary data without the checksums/error correction/crc bytes.
so an ~800MB bin/cue may burn fine as the actual cd image, but obviously you're not going to fit ~800MB onto a CD that barely holds 700MB.
