JoJo's Bizarre Adventure All-Star Battle [BLUS31405]

Copy the edat files present in .config/rpcs3/dev_hdd0/game/NPUB31391/USRDIR to .config/rpcs3/dev_hdd0/game/NPUB31391_DLC/USRDIR to activate the dlc.
But, the game will throw this:
E {PPU[0x1000008] Thread (CRI FS File Access 1) [0x01511174]} LDR: EDAT: Block at offset 0x120 has invalid hash!
E {PPU[0x1000008] Thread (CRI FS File Access 1) [0x01511174]} LDR: Error Decrypting data

Unless you set the affinity to cpu0.
On linux, it's done by:
taskset -c 0 ./rpcs3-v0.0.6-8274-806a7bbf_linux64.AppImage &

In windows, it's probably with the task manager.
