* Make vm::unmap atomic, squash the memory unmapping process inside this function while still using the same VM mutex ownership.
* Make vm::unmap not fail due to random vm::get calls, shared_ptr reference count is no longer a condition.
* Fix sys_mmapper_free_address spuriously failing with EBUSY due to random vm::get calls.
* Fix sys_vm_unmap race condition due to non-atomic vm::unmap.
* Add an optional verification block ptr arg to vm::unmap, used by patches.
* Implement manual selection of config file.
* Implement default config option.
* Fix bug which led to 'force global config' to not work in some games. (any game using process relaunch such most game collections, RDR, MGS4 etc)
* Relax CLI config purpose - instead the emulator forever ignoring any other config except for the one provided in arg, use it only for the CLI-booted game.
This was marked TODO for a long time
- Unsigned remap seems to be overriden by gamma mask (Resistance 3)
- We already know sign mask overrides gamma mask from UE3 titles
* The statement addr += align could have overflowed resulting in either infinite loop or allocating memory outside of the region (illegal).
Add a check checking if it's the last iteration of the loop, then break without adding.
* vm::find_map condition didn't consider the size of the map to be allocated, allowing illegal occupation of [<=0xB000'0000]-0xCFFF'FFFF. (0xC000'0000-0xCFFF'FFFF is reserved for RSX)
- Perspective correction flag multiplies VP output by HPOS.w.
NOTE: Not the same as division by w when it comes to NaN/Inf problems!!
- Restructure indexed loads a bit to avoid re-initializing registers unnecessarily
For some reason XAudio2 doesn't automatically change the device anymore.
So let's just listen for the OnDefaultDeviceChanged event and update the cell audio thread if necessary.
