Disgaea 3: Absence of Justice [BLUS30181]

So, completely at random I got some different output starting this game right now (from a clean start of rpcs3), rather than a read from null block, I got

"[E : PPU[2] Thread (Callback)[0x00261348]]: Unknown/Illegal opcode! (0x0002641c : 0x0 : 0x0) #pc: 0x261348"

In fact, this run it went even further than previously, loading more files such as "START.dat", which sounds really promising! Here is the full log: http://pastebin.com/ZN7AZszZ
