It's possible to use CPCE, save CSW file like it was a tape file. Tape2WAV (direct download), can transform that CSW file to WAV that can be read in other emulators. I'm not familiar with Bouncy Bob as such, though obviously to get it from DSK into a tape format, files need to be loaded in order from tape, a CSW file can hold a number of files just as an original tape would, though one has to be careful not to overwrite code by not ejecting that CSW file.
