Extremely minor, but still getting flashes of red background on that demo/intro screen. Same screen with the 4 portraits of Chun, Dictator, Charlie and Rose that I mentioned on the previous page.

This is really, really impressive work.

I'm having same the issue.  I am trying to apply just the intro timing patch.  I can't use msu-1 as the snes core on MiSTer doesn't support it.

Your patch was just spotlighted on Modern Vintage Gamer .

Long answer:
You can't do it that way, go to main.asm and put ; in the hacks you want to disable, like msu audio. It's complicated to explain and this is not the suitable place.
However i'm not sure if you can do it. You must disable
msu audio.asm
audio tweaks.asm
player samples.asm
I used msu audio, so i disable music samples, in order to fit more in spc. Why you make things hard and complicated?

Short answer:
I don't care. This is the patch, no more help, no more source codes.

Well, Gizaha the achievements are very important, because they make the experience more exciting with the audio enhancements MSU-1, but I would still like an experience without MSU-1 since I don't like emulators and I don't use SD2SNES, a hack without redirected audios. by msu-1 pointers, it would be nice too, do not be furious or irritated, we are already grateful for your achievements and do not abandon us leave your open codes, or your sources of your wonderful achievements, because whether or not you will one day only have the sd2snes option even for everyone. in the meantime we have fun with several mod's at the moment.

He already said that won't happen. I'd rather enjoy more of his superb work than piss him off insisting on a hack he does not want to make.

There is a pack with the original SPC audio on the first page by Relikk, just use that and enjoy.

I'm not mad, answer/suggestion was already told, clearly. If you didn't got it, means that you don't have the requirement knowledge, thus i cannot conversate at techical stuff with someone that don't knows. Learn to respect something complicated that you don't know it's depth.
For the same reason someone will not conversate with me cause of my bad English.

This makes sense. I've got zero knowledge of how ASAR works but could see after some trial and error yesterday before the updated version came out that there's some dependencies between some of the patch files. You need to run everything via the main.asm so it creates the push/pull criteria, macros etc. There's also dependencies between some of the tweak files as well it seems. I found that I couldn't remove even just Audio Tweaks from main.asm as it leaves some unresolved references in the Tweaks patch which in turn results in a failure.

So, I'm now like a lot of people who are no doubt finding this amazing work since MVG's vid yesterday, we're stuck in 1 of 2 worlds.
1: where we can apply the patches but say, remove the "msu audio.asm" patch from main.asm and that will give us all the improvements but very little of the audio.
2: we just suck it up and play it how it was up until gizaha started work on this and hope someone can unpick the redirects to the pcm audio throughout the different patches so there's ultimately 2 versions. 1 with MSU and 1 without. I think we're all aware that gizaha won't be doing that, so it would be down to someone else.

My thinking is that there's probably a relatively simple way to comment out the parts where it switches off the spc audio in preparation of using the PCM files, and as mentioned I think that if the "msu audio.asm" patch isn't applied it never looks for the PCM files but the SPC audio is switched off so you end up with nothing. As mentioned I don't have a clue how ASAR works to even begin to be able to do that and I have even less free time to learn. Good luck to whoever has the inclination to take it on.


EDIT: having just tried the update and removing the 3 asm files that gizaha suggested, there's a load of dependencies/references that aren't met. putting "Audio tweaks.asm" back in and leaving out the other 2, does mean it can complete but you're back to where we were in point 1 of my 2 options. No music.

thanks for the great patch!

the audio absolutely sucks in the original game, i don't mind having it tied to msu-1 at all

See how hard it to describe it with a few words? I don't want to analyze so much in here, i didn't gave source codes for compiling, but for reference.

As for what you are trying to do, i don't have problem to help. Refresh my memory, you want to remove msu music and have back the original audio with the lags, right?

I'm trying to use this on my SD2SNES/FXPak

I patched the rom and can play fine but even with the audio packs I still get no sound, my other MSU1 games have a .msu file, I don't have that on this game. Care to help guys!

BTW congrats on the patch man, the fix included in this patch were some I always dreamed about! (the huge lag most of all)

I wonder why sometimes the sound effects of punches or kicks are muted. It doesn’t seem like if the music channels has a conflict with the sound effect channels.

Looks like if sometimes simply doesn’t load on time. The game already worked like that originally.

you need to make your own msu file, just create a notepad file and change the extension to to msu, for this game

i spent way too long on this yesterday lol - but this is how you do it, you need that file even though nothing is in it

sfa2-msu1.msu

it's a blank file with nothing in it but you need it

Hello! Good night everybody !! here in Brazil this work was very admired,
Yes, I understand about the references, but I confess that I was very curious about the subject.
I suggested that if you could also leave a snes normal audio patch in sfa2, but if that doesn't work, that's fine.
with all these improvements who knows for a cart-mod.
Another thing and that I have no doubts about the operation of ASAR, I know that it has a patch ips to make things easier but,
then I started to get curious because I didn't want to touch the audio pointers redirecting to msu-1, there could be improvements without being msu-1 "bizarre" Sad
This Asar works in 2 ways in win10, one by clicking on the asar181.exe icon,
Another command prompt as an administrator by "CMD" from the run.
you can check the "main.asm" source patch directory by editing as in a notepad
I hope to be taking questions from a layman like me and there are tutorials on the internet for ASAR.
The work done on this sfa2 hack was very good. I liked to see the shin akuma and the rounds load faster,
Taking advantage of the hook, someone would have an uncompressed rom of sfa2 (Dejap) in size 6mb, an original sfa2 had 4,096kb.
or also the decompression files "GFX" being, "gfx-sfa2sdd-1" that makes the game run on old emulators
or even the SDD-1 decompression program Smile Dextor.exe, Dextor.v1.1.exe from (Dejap).
Well the uncompressed sfa2 disappeared years ago only the Star Ocean exists uncompressed yet, where you don't need the SDD-1 chip to work.

gizaha I completely appreciate everything you've done on this and it's amazing. I'm not trying to pick apart all the great work you've done here or even get help with this, I was merely trying to see if there was a way to get the improvements without the MSU audio. Which, in my mind would maintain the rom size of about 4MB, or keep it to a similar size. I had thought that if that was the case then I would try and see if it would run on my snes mini as it's small enough to still fit on the internal memory. (I prefer not to use usb on that, plus I've enough other things that I can play this with MSU audio if I wanted to. I'm just curious about this working on the snes mini.) Very Happy
I get that we could substitute in the spc audio instead of the PCM but that would still result in about 400MB in size for no real benefit. (I'm aware that what I'd like to achieve here is possibly never going to happen, but it seemed worth a shot..... until I realised how much I'd need to learn to be able to do it myself)

To answer your point in what I was wanting to do gizaha, In an ideal world I was hoping to get all the timing improvements but retain the original audio.... which would result in a similar file size to the original rom. I don't know enough about what you've done ( and I'm not ever going to know ) to know if that's even achievable or if all the improvements are directly linked to the implementation of the MSU audio in some way. which would then mean that it doesnt matter what I'd like, it'll never be able to happen and I'm ok with that, if that's how it is.

Goto to main.asm
Before the first incsrc put a random name label with colon, such as asdf:
Put ; at audio tweaks, msu music, player samples
Ready (with the responsibility of yours that you did not break anything else, i didn't bugcheck this method)
For the rest of the questions either are already answered or questions have logic errors.

I commented a lot of the first section of lines in Audio Tweaks, lines 51 to 125... not all of them though. I left the ones for Round 1, 2, 3, 4, 5 keys intact. I've now got spc audio. the only thing is that the Capcom sample runs at about 5x normal speed but I'm not sure why that is. Everything else seems OK for the time being but I've not had a chance to properly test it.
