Dreamcast at FCSC 2021

Post by Quzar »

Another convention using a Dreamcast sample for a reverse engineering challenge. It provides some basics on reverse engineering on the Dreamcast, unfortunately without the original binaries used. Perhaps someone can find it around?

It looks like they used a modified 2ndmix (again) but this time added a tricky routine where part of an encryption was running on the ARM instead of the SH as an extra hurdle to understanding.

And a second, but this one in French:
