Dreamcast Guides : Dreamcast Dumping Script (for *nix)

By darcagn

"I've been buying a lot of discs lately and needed a faster way to both dump/post info and to verify that my discs are good.

Usage: dcdump.sh [dreamcastIP]

Features:

[*]Downloads all tracks automatically using default dumping parameters
[*]Spins down GD-ROM drive when dumping is completed
[*]Prints GDI and file size/hashes to the terminal so that you can quickly compare info
[*]Generates postinfo.txt file with everything ready to go for a perfect post here at Dumpcast. Just write in your ringcode and paste into a new post.

Download http://dumpcast.dcemulation.org/dcdump.sh

Script tested on OS X Mavericks, OS X Snow Leopard, and Ubuntu. On OS X, you will need to install wget first--the easiest way to do this is by using a package manager such as Homebrew, fink, or MacPorts. The hash generation code relies on OpenSSL so make sure that is installed too. Everything else should be standard on any common *nix distro.

Comments and suggestions welcomed. I will be happy to address any cross-platform issues to get it running on your system.
