Kevin Thacker released a new version of his 2cdt utility. With 2cdt, which is a command-line utility, it is possible to transfer files directly into a cdt tape image file.

Changes:
Baud rate calculation fixed
Set/override load address
Set/override execution address
Set/override type
Define pause at start of file (length now can be defined)
Add extra block for bad arnold emulator which skips first block (old version)
Spectrum ROM loader (I use this for my tape games)
Set name of file on tape
