I managed to add a few options to the PRG to TAP tool. Worth mentioning are:
- the ability to append data to an existing TAP file, rather than always writing a new one
- the ability to inject a file into the cassette buffer, at $0351, wrapped into a CBM ROM Header (autostarting turbo tape programs usually store part of their code here, up to 171 bytes)
- the ability to include a 5 second trailing silence, if required
Here’s the tool’s output when invoked without arguments:
