I was just using Sven's UpgradeSplitter to check out some stuff in the upgrade files, and it appears that beta13 (perhaps amongst others) breaks it. There's a new chunk, 0x04, that appears that UpgradeSplitter doesn't know about.

First off, it doesn't handle it very gracefully. It just immediately bombs out. Removing the ``return 1'' line in the default: case solved that.

Second, I was wondering if anyone could help me verify that it is what I think it is. It appears to be an indicator of upon which models the upgrade can be applied. The ``car2'' upgrade's chunk contains ``7\n9\n'', which seems to match the /proc/empeg_id codes for the Mk2 and Mk2a, which seems just right. But the ``car1'' upgrade's chunk contains ``1\n'', which makes intuitive sense, but doesn't match the /proc/empeg_id ID for the Mk1 of 4.

Does anyone have any more insight into this?
