Dump D64

Posted: February 2012

Introduction

Here's a small program that can explore and dump information from Commodore 64 D64 disk images. Currently it's possible to get a directory listing, a dump of the sectors for a directory listing, a dump of the BAM sector, dump a file to the local filesystem, and get a Commodore BASIC source code listing from a file.

Examples

I made a d64 image with the Vice Commodore 64 emulator. I made two little BASIC programs on it and used dump_d64 to view the contents like so:

dump_d64 $ ./dump_d64 -dir empty.d64

10 FOR T=1 TO 10
20 POKE 53281, T
30 NEXT T

The BASIC file listing can output in HTML also which can show the PETASCII characters. To use this feature, Joe Davisson created a list of 256 GIF's from 0.gif to 255.gif that can display these chars. To get the package visit his website: http://joe.csoft.net/
