There are many types of encoding schemes to store data on cassette tapes. Different manufacturers invented/chose different schemes: some proved to be faster or more reliable than others. Therefore some formats are much more common than others. Most of these formats are known by name i.e. Novaload, Cyberload etc and supported by FinalTAP/TAPClean.

I contributed to the study and description of some of these and other yet unsupported schemes. Part of this information is available here.

TAPClean is a console utility whose key features are:

• Detects and retrieves information about TAP and DC2N DMP file contents.
• Tests and reports on the integrity and condition of the files.
• Performs structural corrections and optimizations.
• Develops a library of all detected files as their binary equivalents and allows content exporting.
• Allows conversion to audio format (.AU or .WAV) so TAPs may be played out and recorded back to cassette tape.

• Interactive report of the tape contents with graphical breakdown
• Hex monitor, Disassembler, and CBM BASIC untokenizer for PRG files
• TAP editor
• TAP splitting tool
• TAP repair tool for CBM files
• Graphical TAP/DMP analysis tool

The libtapf library package provides a useful C API that can speed up the production of software that writes TAP files and the cross-development of C64 software. It provides full support for TAP v1 only.
This API comes in the form of a static library (.a) for the GNU toolchain (C/C++ programs), both for Linux and Win-32.

Loaders currently supported:

• CBM Kernal loader, both for program files and sequential data files
• Trilogic v3.2 loader, with or without a bootable CBM file containing the turbo loader
• Turbo Tape 64 loader

This is a project of mine, Tape Maker, that remasters TAP files using prg files.

The libcbmhiresf library package provides a useful C API that can speed up the production of software that decodes CBM hires (bitmap, sprites, fonts) and the cross-development of C64 software.
This API comes in the form of a static library (.a) for the GNU toolchain (C/C++ programs), both for Linux and Win-32.

Current features:

• Export CBM bitmap image to XPM data
• Export CBM sprite data (single or multiple images) to XPM data
• Multicolor and standard modes supported
• Select transparent or opaque background color for XPM images

TAPMoni is a TAP file visualization tool that converts the apparently senseless bytes in a TAP file into easily understandable "graphic pulses". It doesn't require any deep experience about the TAP stuff, thus being a little helping hand for anyone wanting to (better) understand the data structure beyond raw TAP file bytes or just check a newly MTap-imported tape while still in MS-DOS mode.

TAPMoni was born as a C2N head adjustment/diagnostic tool that reads TAP files to perform an adjustment or to point out a problem.
For alignment purposes, this program should be used just for disaster recovery. A C64 native head adjustment tool should be preferred, where available.
Current features are:

• Comprehensive and detailed procedure to align C2N head
• Helpbars provided for CBM Loader and many Turbo loaders
• Graphical output can be saved to a 256-color BMP image

CBM BASIC Lister (formerly C64 BASIC Lister) is a tool to generate an easily readable and printable BASIC listing of any CBM BASIC program (C64/VIC20, etc.) saved as Prg file.
Current features are:

• Optional indent-ation of cycle (and procedure with Extended sets) body, with nested cycles processing
• Optional right alignment of BASIC line numbers
• Optional blank line insertion after a RETURN/END command (and End of procedures with Extended sets)
• Simon's BASIC, Ultra BASIC (ABACUS), and Special BASIC support (and detection)
• Windows version only: Drag'n'Drop a file directly over the application icon (or a running istance's window) to open it
• Windows version only: Font selection between Uppercase and Lowercase CBM Charsets (CBM_Big.Fon & CBM_Small.Fon). You need to copy them in your "Windows/Fonts" folder
• GTK+ version TODOs: UTF CBM fontset to correctly display BASIC listings

TapWAV is a utility that converts TAP files into audio files (WAV format) that can be directly recorded to tapes with an audio recorder plugged to the soundcard output line or burned to an audio CD for later transfer to tapes by means of a Hi-Fi system. No specific hardware is needed for this conversion.
