Exploring the Pippin ROM(s), part 8: Cracking open the Pippin (without the boys)

The Bandai Pippin has finally been cracked. They say a picture is worth a thousand words. So I put together a fun proof-of-concept demo, and made a video to summarize these last few months. For an in-depth technical explanation of what’s happening here, here’s some further reading: Exploring the Pippin ROM(s), in which I do […]

In part 1 of this series of posts, Daniel suggested taking a look at the role the SCSI Manager plays in the Mac’s– and by extension, the Pippin’s– startup process. I took a break from examining the auth check code to dissect how the SCSI Manager behaves at startup on the Pippin, with the ultimate […]
