So, my Zero 3 board is dead, and I was curious if anyone in the US would be willing to rewrite my SIMM with the decrypted code, as I don't have a CPS3 setup
Get a Infinity Key, no one uses the decrypted sets anymore (I personally believe some decryption errors still exist in these).
I'm pretty sure it will install the same way as normal CPS2, but maybe ask @undamned first.
