Crystal plays backups with the hacked firmware. The DMS4 needs the Toxic Bios/OS if you want to play backups. The Matrix Infinity is a great chip too. The Crystal chip has a program called bootmanager that can play homebrew files. Matrix infinity has a similar program. Ghost2 has those features with the firmware disc and manager disc. The ghost2 flashes are not allowed here. I heard it has a built in debugger for those programmers but the ps2dev software can do that. I hope this helps.
