Add a simple Python script that does a basic normalization on
the game INI files and run it across all the files we have. This
normalizes the sections, their order and comments, and the whitespace
within them.
It also removes the sections Video_Hardware, Gecko, and Wii, which
should not be in the game INI files we ship by default.
At the end of July 2011, LM published a free DSP ROM that works with games
using the Zelda UCode. His ROM only has the code to handle UCode loading and a
few utility functions, the rest is missing. This includes the four large sound
mixing functions used by the AX UCode and the DROM containing coefficients used
for polyphase resampling in AX.
This is an improved, updated version of this ROM, which changes the following:
- We now have a free DROM that works for polyphase resampling by "emulating"
linear interpolation. The coefficients contained in the DROM are normally a
list of { c1, c2, c3, c4 } which are used to interpolate a sample value from
four previous samples:
out_sample = prev1 * c1 + prev2 * c2 + prev3 * c3 + prev4 * c4
The coefficients are chosen depending on the fractional part of the current
position (basically, our position between the previous and the next sample).
We can use this fact to generate (c1, c2, c3, c4) for each possible
fractional part so that:
out_sample = prev3 * curr_pos + prev4 * (1 - curr_pos)
Which is the formula for linear interpolation between prev3 and prev4. Linear
interpolation is not as good as polyphase resampling but it still works very
well and I couldn't really hear any difference between the two. If someone
wants to generate real polyphase filter coefficients, they are welcome to
submit a patch.
- The IROM now contains the 4 mixing functions used by the AX UCode: mix_add,
mix_add_two, mix_add_ramp, mix_add_ramp_two. They are large, inlined
functions (probably for performance reasons) in the official DSP IROM, our
version prefers to use a loop. This *should* be more performant with our DSP
JIT implementation, but I did not benchmark that.
Because the new DSP ROM is working just as well as the official ROM in 95% of
cases, it is now shipped by default with Dolphin and will be used with DSPLLE
if you don't have an official DSP ROM in User/GC. It will still display a panic
alert at every boot to notice you that you are using a non official DSP ROM
made by us, which is not perfect.
Games using the CARD, IPL or GBA UCodes are still broken. I don't know what
games this actually impacts, but this is a very small proportion compared to
what works.

Fixes two memory leaks, one is pretty bad for OSX. Yell at pauldachz if this doesn't work. Or... say thanks.
Added a BluetoothEnumerateInstalledServices call so that the wiimote remembers the pairing.
Make ARMJit core default CPU core on ARM architecture
Fix a StringUtil regression from the arm-noglsl merge
Small improvement to cmpli/cmpi in ARMJit.
Merge latest ArmEmitter changes from ppsspp while we're at it.
Ah. I blame vim on this typo entirely.
Add disabled code for authenticating wiimotes on Windows.
Add the missing FPR cache
Buildfix.
Yell at the user if they change window size while dumping frames, and some other avi dumping stuff.
Not sure if this is the right way to handle this, but it makes the save states perfectly stable. That's all that really matters, right?
Abort loading states from incompatible graphics backends.
ARM Support without GLSL
Improve VideoSoftware save states. They are fairly stable, but not perfect. OpcodeDecoder::DoState() needs to be fixed.
Begin implementing save states to video software. Kind of works, sometimes.
Make error message for loading save state with wrong dsp engine shorter.
Abort load state if it uses a different dsp engine, instead of crashing.
Update the gameini of F-zero. Efb to Ram is no longer the default choice.

Build fix
Corrected a state bug where newly loaded dols did not have their patches applied.
Changed the HLE system to allow it to hook the beginning, the end or replace the entire function without changing the GC memory. Fixes Kirby's Return to Dreamland. Added a way to categorise the type of HLE function. Currently, there are debug, floating point, memory and generic functions. Added a HLE function for OSGetResetCode (Warm reset). Fixes the CSI games. Added a switch to disable all of the HLE functions if the idle skipping option is disabled.
Added some IOS version checks and code to clear memory before loading the dol.
Added support for Reset (from menu). Fixes Sam & Max.
Added an IOS check as games which use IOS older than IOS30 do not need to be HLE'd. Added some stubs for Reset to Menu and SSBB's load from disc partition. Fixed loading Fate of Atlantis from the Indiana Jones and the Staff of Kings game.
Added argument detection and passing to the loaded dol. This fixes the Wii Sports+Wii Sports Resort bundle pack.
Added preliminary support for ES_LAUNCH (Wii Multi-boot games) by using HLE to hijack the OSBootDol function.

Metroid Prime Trilogy is working. Wii Sports+Wii Sports Resort is not working. Any games which can be played using the dol replacement trick should work here.
Suspect that the DOL's are meant to receive an argument list which has not been catered for in this code. This probably also means that the Metroid Prime Trilogy games are locked in Veteran difficulty for the time-being.
