Below is the Dreamcast the BIOS was dumped from and the chip it was beamed down through. I’d used httpd-ack-20080711.zip and XDP.rar to get me my BIOS – MPR-21871.zip. Turns out it is version 1.01c and has a misspelling of disco or something. Overly it wasn’t too exciting, but great to be able to dump the BIOS from my own Dreamcast. Last time I even tried to do that would have been about a decade ago. Glad to see it worked much easier this time than previously.
Furthermore I also discovered you can easily generate CRCs using Terminal on Mac OS X. Simply type crc32 and then the path / filename. Just like that the CRC is generated right there for you, free of charge.
