problem with neogeo/ps2 6b emulator

[Ps2fanatico]

I'm having trouble since the new emulator with cdda support came out.
All my games that I have work fine but the only thing that doesn't work at all is the music in the games.
I already tried everything, from reseting the emulator to checking the cd backup games that I have.
Could any one tell me if somebody had the opportunity to make this cdda work at all. Since I'm reading all the threads and I'm not seen to have any lock with my backups.

:mad:

dumb question, but did you activate it ? as it was off in the settings of the last version, and since settings are saved and loaded from the MC, you must activate the CDDA from the menu at least the first time.....

[Ps2fanatico]

First of all, thank you very much for answering my question Mr. Evilo, and keep up the good work and congratulation for this wonderful neocd/ps2 emulator that your are building.

Aswering your question:

Yes, I already try turning the cdda on, and reseting the emulator once the game is running, but I didn't have any luck.

1) Do you have to erase the old save from the 6a version in the memory card or it overwrites it with the new 6b version?
2) The games that you try with your new 6b version are original or backups?

Tip : What I've been doing with my backups is running them with neocd emulator in my pc and all the game's music and sounds work fine. So, that shows that the games that I have, are already in the wav format, since the emulator that I used supports this format and when I put that cd in any cd player it comes up like a regular music cd.

Thank You,
Regards

hi Ps2fanatico !

sorry, but I warned you that it was a dumb question ! it's strange that you can't get the music working, most of all if your backups are working with the PC version... ? which version of PS2 do you have ? which boot method do you use ?

and to answer your question :
1) Do you have to erase the old save from the 6a version in the memory card or it overwrites it with the new 6b version?
-> no, you only need to activate the CDDA in the ingame menu
2) The games that you try with your new 6b version are original or backups?
-> only backup copy of my original games...

sorry, but I can't help you furthermore for the moment...

I also have another beta running on my PC with some enhancement/fix on the CDDA code that I should release next week.

And after that, I will concentrate on the remake contest we will launch for september with the froggies (froggies.ps2dev.org) !

Thank You for answering my questions Evilo.

My ps2 console's version is scph-39001 and I'm using for the boot part the Swap Magic cd.

Today I tried it again and I have the same results, the sound is fine but not music at all.
The only think that I could think of is, that maybe I'm missing some files when I burned the 6b emulator cd, but I don't think so.
If You could send me the order in which I have to put the files in cdgen please, I'll appreciated.
And if you could think anything also that I could do let me now.

Thanks again Evilo.

I have this same problem.

CDDA wont click to on and i cant get the emu to load any CD games.

Only way i can get it to run any game is to copy the entire game to a "cd" folder.

Ill try again today fresh from the start.

iichh.. sorry !!

well, honnestly I don't understand why it's not working with neocd/ps2 if the same copy is working on the PC version.

is anybody outhere can make it working with the same burning/boot (cdgen/swap magic) method ? or is it a problem for everybody ?

[phoangkhoae]

i couldn't get the music to work either. Same method (burning, cdgen, swap magic). The CDDA in the ingame menu was turned on

[evilo]

Ok, here is my idea about the swap, just tell me if I'm wrong (never used it since I had both of my ps2 premodded).

When using swap method, only the TOC of the first disc is seen. So when, after, you insert the neogeo game, the emulator only see the swap magic TOC (so without CDDA).

-> TOC is not refreshed with swapmagic ??

is this coherent for you ? I'd like to understand and to find a workaround for this.

I checked again in the emulator, and the code is doing (more or less) :

1. check for a neogeo CD (swap screen)
2. load games files (*.spr, *.fix, etc..) from the cdrom
3. init audio (audsrv)
4. init & check for cdda tracks

and this is correct...

let me know,
evilo

[Ps2fanatico]

:) This is a very good theory Evilo,
I think it might be the problem; Since, like you said, the emulator is loaded without cdda.
But what if you could make the cdda from the emulator already activated, instead of turning on once you boot it.
This could probably solve the problem or perhaps We could give it a try.
Good thinking Evilo.
Let me know if could be posible to release 6b with the cdda on. And I will try it my self.
Thanks,
Evilo

the CDDA is turned on by default in the emulator code (in last version ->0.6x).

You have to turn it on, because it has been turned off by default in previous version and saved like this in your memory card (where option are saved).

If you trash you ngcd save on the MC and then start the emu, cdda will be turned on by default.

Also, about the TOC issue,

while browsing the internet I found this about the swap magic 3.6 :

# TOC refresh mechanism allows the PS2 Swap Magic 3.6 to play all of those large TOC games which could not be played before.

so... if I understand well, if you manage to burn your neocd game with a TOC larger than your swap magic, it could work ??

damn... we don't have any swap expert here... :banghead:

mod your consoles guys :rolleyes:

Hello !

I'm not an expert but i have a little experience with swapping:

PS2 and PSone cd are mode2 cd, and no game is bigger than 621 Mb ( 72 min ). But breaker pro is compatible with both systems, it is a 100 min PSone CD.
Yes when you swap, the console use the TOC of the first CD to boot the second.
I use swap magic 3.0 and there is no TOC refresh.
I use independance exploit ( and cogswap loader ) with breaker pro for big cd.
Both discs are mode2 CD.

Now the big problem is: the PS2 ( and i think PSone too ), don't recognise mode1 CD ( only with a mod, maybe on the last version?), and the NeoGeo CD are all mode1 mixed-mode.

To make it work, i copy all files on the pc, make a mode2 CD with them and the emulator, and swapping with Swap Magic or other.
For CDDA, i try CDrom mode 2 XA to put the audio tracks but no audio is working ( only sounds FX ).
I think swapping is not compatible with CDDA, as you said, we need a mode 1 cd working with ps2 and having audio tracks on it.

Maybe with swap magic 3.6 ??? It would be very nice !

Evilo,

my dream is the emulator can read iso of the games and have a browser.

If there is a browser and the ability to read iso, we could put many games on a CD or DVD.
With this options, all nomod users like me could have CDDA working unless it will be impossible ( i think ).

Thank you either for you really good job, i prefer play without music instead of not playing at all.

PS: Most of CD i have make for 0.5 version with the emulator inside don't work with 0.6 ! ( boot 0.6 and swap with old CD )

[evilo]

So still about the swap and the toc refresh issue,

After a few investigations, tries and talks, it appears that it's impossible to bypass the ps2 routine to read the toc (I wanted to make a raw read of the sector, but since the area where the TOC is stored is a special one, it cannot be accessed that way, and you must use the getToc function of the drive).

So my next try will be to try to force the TOC refresh , altough I still don't know how to do this...


Else Last chance is to find a way to make it working, maybe with swap magic 3.6 that allows to refresh the toc ?

So at this point, tell me if I'm wrong, but CDDA are working only on modded PS2 ?

If neocd is launched from the MC (using the exploit for i.e.), it is not working ?

sorry,
evilo.

Yeah, now that the emulation is almost complete (cdda is almost done), I was thinking about adding iso support MAYBE in a futur version, once I would have a bit more of free time to work on it.

Then with iso support there is two solution :
ISO + MP3 : but the ps2 is not powerfull enough to emulate the neocd and play mp3 tracks
full ISO (including CDDA) : yeah, that way the audio stream (for music) would be read from the ISO file, instead of the CDDA track and would allow nomod user to benefit of the music. But since full ISO images are big, that would only be possible on a DVD (I mean to have more than 1 game per cd/dvd).

anyway, even if having this and a little browser would be great, it's not for tomorrow, sorry but I don't have the time to implement this right now, but I keep it in mind for later !!

and Thank you very much for your support ;)

we need a mode 1 cd working with ps2 and having audio tracks on it.
mode 1 = data mode only (one track)
mode 2 = data track + audio tracks
There's no way to put audio tracks on a mode 1 disc.
