Codename of the newer ps3 syscon models. Latest advances on this chip will be documented here.

Generating the keys for patches

00 00 00 00 5F 5F 5F 5F 53 43 45 49 53 59 53 31

• replace 4 dots with soft id in decimal form, xor with 0x140 key and with cipher patcher key and encrypt with master patcher key to obtain cipher master key for that soft id

• replace 4 dots with soft id in decimal form, xor with 0x140 key and with hasher patcher key and encrypt with master patcher key to obtain hasher master key for that soft id

only one patch exists, with soft id 0832

Modus Operandi

• Reuses the first 0x1E (30) keys from the 64 available on old syscon format from old ps3 syscon
• UCMD format, similar to ps4
• Patch generation differs slightly as well as format
• SNVS has an extra layer of crypto, making it 3 layers total, opposite to old ps3 syscon
