[SAVEVERSION+] VM struct changes.
- Serial/title is now linked to disc, instead of running ELF.
- Save states can be created during BIOS boot.
- Patches now apply based on the executing CRC, and only after the
entry point starts executing (fixes multi-game discs).
- Add "Fast Forward Boot" option.
- Split achievements download and activation, downloads occur on
initialization, but are not activated until after the ELF loads.
- Prevent HostFS access while in PS1 mode.
- Remove multiple sources of truth for ELF/CRC/etc.
- Move ELF state from global scope to VMManager.
- Prevent game fixes and hw fixes being active while booting game.
- Simplify game update.
- Flush recompilers after ELF loads. No point keeping boot code around
which gets overwritten.
Guest memory is now mapped into a shared memory/file mapping, for use
with fastmem.
64-bit and 128-bit arguments are passed by register/value instead of by
reference/address.
LDL/LDR/SDL/SDR now use 64-bit GPRs instead of SSE.
These have no meaning in x64 (apart from throwing compiler warnings),
and we don't do 32-bit anymore. Also saves needing to include
`Pcsx2Defs.h` in files which don't otherwise need it.
Now, IOP breakpoints work nice and reliably in both interpreter and
recompiler, exiting as soon as possible, without leaving the event state
indeterminate.
Add GoemonUnloadTlb function that invalidate TLB cache.
Currently the function is only used on the interpreter. It fixes TLB error after a reload of data.
Next step: porting to the recompiler
When a tlb miss is detected current instruction must be skipped. We need
to immediately switch to the handler
Typical instruction bug case:
lw a0, 0x8(a0)
a0 mustn't be loaded if we have a miss
v2: create a dedicated exception for tlb miss
v3:
* rename exception to CancelInstruction
* add a basic state machine on the exec loop so we keep same behavior
for eeloadReplaceOSDSYS and eeGameStarting
v4: remove assert
Tlb mapping is stored @0x3d5580 (GoemonTlb[150])
The function that will populate the tlb is around pc = 0x356250, ra = 0x33ad48
The idea is to add a callback on 0x33ad48 block that will populate the tlb based on
ee mem content.
Note: The hack is based on previous Virtual PS2 => Physical PS2 LUT
Path3 Masking: Fixed a bug which caused persona 3 not to boot, previous a hack had been put in place to get around this.
VIF: Fixed a VIF error with the rare game Realta Nua, now goes through the prologue correctly. Game requires the EE timing hack to get rid of most of the noise (Path3 masking problem with new GIF unit, unfixable).
Expecting bugs, I will be monitoring this.

Pcsx2 now has a gifUnit class which acts like the ps2's gif and executes a single gif transfer at a time (and performs path arbitration according to priority and path3 slicing).
This new code is generally a speedup for most games. Particularly VU heavy games like GoW.
This revision breaks old saved state compatibility so don't update if you wish to keep playing with your old saved states.
Leave comments if this revision fixes or breaks anything...
Message to GS Plugin authors:
This new code now uses only 1 gif callback to transfer data to the gs plugin (GSgifTransfer).
pcsx2 also is garaunteed to send full GS primitives to the plugin. So you don't have to account for partial-transfers anymore.
Thanks goes out to shadowlady who tested around 500 games for me :D
Note 1: The old gif code is still in this revision, and can be enabled by the USE_OLD_GIF macro. The old code will be deleted soon.
Note 2: This revision also enables assertion dialogs in devel builds, and changed a lot of assume cases into assertions.

* Both INTC and DMAC exceptions are now issued together when possible (0x400 | 0x800 to the CAUSE register, respectively)
* CPU exceptions are checked on every event now, instead of using scheduled interrupts on bits 30/31. This removes the need to constantly reschedule events during interrupt-disabled states.
* CPU exception test is moved to the top of the EE event test.
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@3728 96395faa-99c1-11dd-bbfe-3dabce05a288
* Now using SSE for all hardware register reads and writes (mainly MFIFO stuff) [don't expect a speedup, really -- its more of a code simplification in this case].
* [refactoring] Changed the EE Memory (vtlb) to use the u128 type instead of u64 for the 128-bit loads/stores (see mem128_t typedef)
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@3626 96395faa-99c1-11dd-bbfe-3dabce05a288
* Some minor exception/error handling fixes and improvements.
DevNote: the BOOT2 elf loader fix is still a hackfix. I documented the proper fix for mimicking PS2 BOOT2 parsing, but not in a mood to do the full proper implementation right now.

DevNote: I could have left the code for the freezes in, except I *really* don't want us to ever have to resort to using such a system ever again in the future. For anything. (its just not safe on modern optimizing compilers)
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@3392 96395faa-99c1-11dd-bbfe-3dabce05a288
I also re-implemented R5900 runtime exception handling for TLB Miss and such (devbuilds only, for now).
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@3335 96395faa-99c1-11dd-bbfe-3dabce05a288
* Made all database key comparisons case-insensitive, so that "patches" and "Patches" both work as expected, etc.
* Applied patches should be remembered properly now when using suspend/resume and savestates (hopefully -- didn't test savestates yet).
DevNotes:
* Reorganized all game database code into a generic interface used by the emulation core (IGameDatabase), and app-side implementation (AppGameDatabase) that loads the files and provides info in a thread-safe manner.
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@3223 96395faa-99c1-11dd-bbfe-3dabce05a288
* Added DX11 support. DX11 enabled cards now give a +~40% speedup
* New SSE-X instructions we invented for PCSX2. Give a +200% speedup even on old CPUs.
* Full 64bit support. If you have 64 bit windows, be prepared for a 300% speed up.
* Implemented new DMAC, so far we have ~15 games that show improvements.
* Added support for USB-enabled vibrators. Feel the full pleasure of gaming, now also with PCSX2!
* SPU2-X now decodes Dolby Digital 7.1!
* Please test to find any bugs in the 24-thread code, it's a bit complex so some tiny bugs might have crept in.

Changes to patch system required by this and fix for boot time (first field = 0) patches when booting through BIOS.
Store Sony part number for the game disc globally for future use in selecting game fixes, patches, providing information to the user, etc.
