Kudos to this engineer. I also had this on my longterm list :D. It's definitely a good thing for all collectors and people preserving old video games.

Watched this in full yesterday evening. Really astonishing stuff, not to mention incredibly admirable. I know I'd love to see something similar for the PS2 in the future.

I heard about this over on the GDEMU blog.

Pretty incredible!

I guess he means the DNAS problem. I'm working on it :D Currently I'm stumbling through a wood of encryption, decryption, checksums, keys, modifications, tricks, more tricks and even more tricks. I know pretty well now why my DNAS answer packet isn't accepted (a combined sha checksum of the question packet, modified and buried in a lot of DES encryptions overlaying themselves), it just takes a lot of patience to fiddle with the selfmodifying libDNAS and not to loose track. But I'm sure it is possible to emulate it.

So, you were able to spoof the SSL cert? wow.

In short: Yes! That was the first step and I found a solution that works for all gateways (jp,us,eu).

oh wow! Props to that guy for doing all of that in his spare time.

Experience and patience... I guess Baron Zemo was right.

Nice, does this mean some of the most rare games finally can be ripped?
