This is a simple tool to generate a TZX tape file from any of the tape formats supported by libspectrum, changing any block into a turbo block setting arbitrary timing values.

I'm not very familiar with libspectrum but the resulting files seem to be OK when analysed with Tapir, so I think the result is reliable.

• gcc
• libspectrum (and its development files)
• make

Once the requirements are met, just run make.

For example, to change blocks 4 and 5 (first block is 0) of test.tap to turbo blocks with the timings of Biturbo 1, we can run:

tap2turbo -t 2165:8350:714:714:486:833 -o test.tzx test.tap 4 5

Run the tool with -h flag for help.
