If, hypothetically, this were to happen, would it be possible for someone to take a look at the memory test code and make it test any additional memory found? It's hardcoded according to hardware release at the moment.

This would greatly facilitate upgrading other peoples' players as only the mainboad would need to be shipped. At the moment disks are needed to soak test the upgrade.

As for the other questions, I'd suggest pinging Mark by email. He's been very quiet here in the past couple of weeks.
