I designed this project after I recently dug my Commodore VIC-20 out of storage.  Some of my game cartridges needed much cleaning, and even after that, some didn’t work anymore.

The Multicart was developed so that multiple games could be played on a single cartridge.  The VIC-20 had many excellent arcade games like Pac Man, Donkey Kong, Frogger, Dig Dug, …ect.

This cartridge combines 32 of the best VIC-20 arcade games on one cartridge.

CBMXfer is a GUI, or Front-End, to several command-line utilities. CBMXfer makes using those utilities easy by providing a familiar windows interface that removes the need to learn the commandline syntax of each program.

These commandline utilities are:

• CBM4WIN – transfers files/images to/from a real CBM drive connected via an ‘X-cable’ on the parallel port.
• CBMLINK – transfers files/images to/from a real CBM drive connected to a real CBM computer connected to the PC via a serial cable.
• C1541 – a utility from VICE that works with CBM Image Files (ie: D64/D81 files).

What can I do with it?

• Transfer files to or from real CBM drives.
• Create D64 and other images files from real CBM disks.
• Write D64 and other files back to real CBM disks.
• Transfer files from WITHIN Image Files.
• View Commodore BASIC listings for all machine types.
• Simple file operations like copy, delete, rename.
• Launch VICE and attach disk images plus autorun.
