I've just downgraded from 2.5 to 1.5 en know i use devhook to start my gta copy. But I want to play 2.6 backups. Is firmware dump a tool to remove the 2.5 firmware from my flash? And can i play 2.6 games if I follow the same staps as with the 2.5 firmware only using the 2.6 eboot? And won't my flash internal memory get full if I put so much different firmwares on it?

I'm a 1.5 nooby so I don't really understand these things
