Like said in that issue, it seems the limit passed to XamContentCreateEnumerator is actually a limit on how many results XamEnumerate should return per call, not a limit on the number of enumeration items in total.
These changes fix Sonic Unleashed not loading more than 1 DLC (it passes 1 as the limit, but then loops over XamEnumerate to load in each DLC one at a time), and likely many other games.
This is a regression in functionality and performance, but a much better
foundation for the future of the project (I think). It can run basic
apps under an SSA interpreter but doesn't support some of the features
required to do real 360 apps yet.
This should make it easier to find files and (in the future) split things
up into separate libraries.
It also changes around emulator initialization to make it a little more
difficult to do things out of order and a little more sensible as to when
real init work happens.
Also adding a skeleton audio system/driver and reworking CPU register
access to be more extensible.
