MakeTZX 2.35 beta1 This unreleased version contains some bugfixes and introduces the -t switch which suppresses the generation of standard ROM blocks in favour of the turbo type (0x11). The MakeTZX utility is used to convert real ZX Spectrum tapes into TZX files suitable for Spectrum emulators and digital preservation purposes. The archive contains the user manual which describes the program features in detail. As a complement to the command-line interface of the utility, a graphical front-end for Windows called MakeTZX-WinGUI was also produced.
