Hacking couple of noob d2pro questions

[DaMummy]

1. are all wii firmware updates save on the d2pro? 2. when trying to run gamecube backups on d2pro, is there a way to burn 2 games onto one dvd and be able to play em both? i think there was something else i needed to know, but cant think of it atm, will post again if i have any more questions
