CPS2 desuicide
#358696 - 09/16/16 12:58 AM


Looks like the instructions on how to desuicide a CPS2 board have finally been released
http://arcadehacker.blogspot.com.au/2016/09/capcom-cps2-security-programming-guide.html

Its unclear to me just what the relationship between the key values in the ArcadeHacker_CPS2.ino file and the stuff in MAME cps2crypt.h is (or how to go from one to the other) but I am sure smarter people than me will know whats going on (that or the guy who figured it all out will share how to go from MAME keys to hardware keys)

But in any case its still a great achievement.

This may make it clearer.

The only thing you can rely on is that at any one time there will always be someone smarter than you about something.

I think he will.
