I found a missing new line in xboxkrnl_video and corrected it. I also found the name of an unknown function in xam table. Here is my source for it. https://pastebin.com/NbpVq9jG
Resource locators are just strings that say where to find a resource, they can either point to a file path or to an XEX resource.
Normally the Gamercard/SharedSystem exports use XamBuildResourceLocator to make a locator for the resources inside xam.xex.
But since our xam won't have those resources I've made it point them to a local file instead (by passing 0 as the module param for XamBuildResourceLocator).
The resources will have to be extracted to the XEX's local path for it to find them though (and XEX will need to have media:\ symlinked too)
The XamFormat*String exports are really windows-only right now, but they'll at least empty the buffer for other platforms.
They'll also always output MM/DD/YYYY no matter what locale the system is, on 360 this is localized properly of course.
I've renamed XamBuildSharedResourceLocator_ to XamBuildLegacySystemResourceLocator too since that seems to be the proper name for it.
In earlier Xams this just pointed to ...SharedSystemResourceLocator (as does this code), but later versions seem to have their own function.
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.
