What is the point in doing this tutorial if it gives no effect on this specific game? How can it improve the stability of the game?
I really didnt get the hang of the tutorial that ED2 did and just made my own interpretation of it.
I just downloaded dsp_coef and dps_rom and placed them in Dolphin/user/gc. Have i now completed the tutorial and made it possible to run DSP LLE?

I tried to run the game and got this message http://i50.tinypic.com/zv4v4g.jpg which resulted in no sound at all.

If someone wants to help me, please explain it as easy as you can. Im a total retard when it comes to these things.

I'm going to try to explain once and for all :p When set to use LLE, Dolphin emulates the GC/Wii DSP (the component responsible for sound) as accurately as possible. With it, you'll get better results than HLE audio, if your system can handle how demanding LLE audio can be. To use LLE audio, you must provide Dolphin with the dsp_coef and dsp_rom files. These files come in two types:

1) The real files are extracted directly from the physical console itself (e.g. a real GC or Wii). These can only legally be obtained through ED2's tutorial, there are no shortcuts. Since these files are directly from the original hardware, they'll work with every game that Dolphin can use LLE audio.

2) What's known as the reversed iROM made by LM1234. These files were reverse eingeneered to work similarly to real DSP dumps. However these files were only designed to run with a limited number of games, the ones that use the Zelda uCode.

You downloaded the second one. MGS:TTS does not use the Zelda uCode, therefore it won't work. The reversed iROM is for people who don't want to dump the real DSP files and want to play a Zelda uCode game. For everyone else, you must get the real DSP files from an actual GC or Wii. If you want the real ones, follow ED2's guide. If you're confused about the process, feel free to post a question in that thread.

That said, with your specs Dolphin should run good even with LLE audio enabled. Did you try the D3D11/OpenGL backends? This game works much better on those.

BTW, whatever issues I was having when using Accurate Vbeam with HLE is gone in the 3.0-710 . I just wish it was as fast as the official 3.0 release.

I tried all possible video backends, and I have Accurate Vbeam enabled for this game as well. With HLE, sound stutters, but not so much through the gameplay, but sound often stops in the cinemas, leading to hanging of the game. With LLE, sound just stutters badly all the time.

I don't know about HLE + Vbeam but in LLE's case Vbeam must be disabled.
OpenGL is the only backend that renders the minimap correctly so dont really have a choice.

hey i think i almost find the perfect setting for this at least in my case

http://i46.tinypic.com/288xcp1.jpg

sound never crashed till Meryl cinematic !

version i use 3.0-716 x64

but something went wrong in Meryl cutscene , before Meryl shows with underware pants , but then
after i play it again Meryl directly shows with that Military trouser ? xD

Thanks for this advice. In fact, with Vbeam disabled, LLE works normally. Actually, it works the same as HLE, I mean there still is sound stuttering throughout all the game, but at least no more hangs within cinemas. However, sound stuttering became more strong and annoying. As for OpenGL - I don't know, the minimap works as it should with Direct3D11 and Direct3D9 for me. However, Direct3D11 causes some artifacts on the screen, but Direct3D9 works perfect.

The reason you guys are having problems with LLE audio + Vbeam enabled is maybe that VBeam works best around 64-65 VPS than the typical 60 (54-55 in PAL version of course). When I use LLE, I usually have to put Framelimit on audio (audio throttle in past revisions) so the sound can play as smoothly as possible.

I have never had any issue with the minimap not displaying properly on D3D9/11. OpenGL is what doesn't work for me, but I realize that's just my PC.

I have not dumped this game yet, but using LLE audio + Accurate VBeam emulation, I've gone as low as 30 FPS (Tales of Symphonia) and still had perfect, stutter-less audio, and I've consistently had it running anywhere from 40~60 on other games. It might have more to do with audio throttling. I always have this option set, so I haven't exactly tested LLE audio + Accurate VBeam emulation without it.

My bad, I meant the VPS. When the VPS is in that tiny range, that's where it sounds best.

Oh, if it's VPS then yes, you are correct. Personally, in regards to VPS, the lowest I ever got with decent sound (LLE audio + Accurate VBeam) was about 54~55 (91% game speed). I actually couldn't get the game speed to drop any lower in my tests with my desktop, but I've noticed that range when I tested on my laptop. It may depend on the system, but definitely, the high upper range for game speed creates smooth, stutter-less audio.

Please explain how to enable audio throttling in latest builds. I really want to get stutterless audio. And what's VPS? And please make the screens of your settings if it's not inconvenient to you.

[Shonumi]

The newest revisions keep audio throttling Configuration->General tab->Framelimit. Just set it to audio. Let's ask NaturalViolence what the VPS is:

NaturalViolence Wrote:VPS=speed of cpu (max number of frames per second the gpu can draw based on how fast the cpu is running)

I doubt my settings will be good for this game, as I haven't played it. If you care to have a look though, just google "Shonumi YouTube user" and I have it posted in my video (the only one I've uploaded so far).
