backbit-tool v1.3.4

BackBit-Tool

The BackBit Tool is a fully open source cross-platform JavaScript application that creates .BBT files for use with the BackBit cartridge for Commodore 64.

The BBT file format offers the following innovations:

• Prepend SID music and title screen/screenshots
• Autostarts to any program
• Incorporates up to 8 disk images (D64/D71/D81/D8B)
• Supports up to 4GB of binary data
• Tags important details about the program, including text and screenshots

While this format is designed to integrate with the BackBit cartridge, it is likely that emulators will eventually support this format once there is enough demand.

For the latest compiled build, find it at http://backbit.io/downloads/Tool/.

The cartridge is available for purchase at http://store.backbit.io.

BBT File Format

This is a (somewhat) human readable format when viewed in a hex editor with a column width of 16 bytes.

All fields begin on 16-byte offsets.

See details here: https://github.com/evietron/BackBit-Tool/blob/master/src/bbt.js

D8B File Format

This is a new format, similar to other disk formats but with capacity for about 8 regular disks and directory entires to match.
