cdda psx games on psp without popsloader question

Hi,

i am messing with psx games on psp lately. succeeding on converting most of them but there are major problems with cdda games.

only spesific firmwares on popsloader works with them (which either doesn't work or works with no sound unless a headphone is connected on my psp go.)

but that is not true for psn downloaded psx games. cdda games like tomb raider works perfectly well on latest firmware. as the latest pops doesn't work with cdda, i read that sony converted cdda tracks to atrac for enabling them. does anyone have more info on how sony made cdda psx games work with latest pops?

i tried to get the original .bin / .cue of the psn pkg of tomb raider (to compare with a vanilla psx cd .bin / .cue to see what sony edited) but both popstation and psx2psp crashed trying to get .bin or .iso out of the eboot.pbp.

any help on this issue would be great.

also popsloader doesn't work with fullscreen on tv out unlike psn psx games, that is a disadvantage too.

Irony XD
We have started a war in topic because this format. At last seems i have right.
The only solution is dump your game with clone cd, and convert your game with psx2psp selecting the .ccd.

BTW last popsloader it's a mess of bugs

It's a problem of go model, with 100x and 200x this problem doesen't exist

 

AT3 audio would definitively make sense, especially due to the fact that these digital versions are supposed to be downloaded and size does matter. As for some versions of the emulator not working with CD-DA, I think that's a huge misconception. Popsloader does nothing more than loading a different version of the emulator modules, meaning the feature should be supported in almost all of them.

 

Trying to get Mega Man X3 to get CD-DA and not crash wasn't fun, I can say that much. Forget what I did.
But it needed an older version to work right. Old enough to lack custom image size options. So the PAL version's aspect ratio was wrong.

 

latest versions of pops emulator just doesn't support cdda, sony left that feature out. it is not a misconception and easy to try. just convert a cdda game on the wiki list i linked, then load it in both 6.60 pops and an older pops via popsloader (about 3.71 should be fine). you won't hear cdda audio on 6.60 firmware.

@master991: i know popsloader has problems both on psp go and psp 3000. that was why i specified my psp model. though this doesn't change the fact that sony can make cdda psx games work with full audio (probably via converting cdda to at3) on 6.60 firmware and we cannot do the same for homemade converted psx images.

@Lum: Yup, i am doing the same for destruction derby raw. here are the details in case someone is wondering. find a compatible version of psx2psp, make your image in .ccd/.sub/.img clonecd format (that is important, .bin/.cue won't work), use a pops about 3.71,3.72 etc via popsloader. i remember 3.52 works too. older versions work fine too, but they lack different display options as you pointed out. also say bye bye to your psx savestate option if you are a psp go user. also you will only have the audio via headphone because of the required pops version.

 

4.01 is last that uses cdda tracks AFAIK and will not work with GO for me at least but works on my 2G and 3G

 

thanks for the info. as i only have a psp go, i can't test 3.71 to 6.00. and below 3.71 only has audio when headphones are plugged.

i am trying to source the information where i read sony used at3 instead of cdda to make the cd audio play in latest pops versions, but still no concrete source.

 

They changed the media engine sub CPU on the PSP-N100x, no ? Also this stuff could have to do with how PS1 emulator works on the PS Vita (as it has no media engine sub cpu)

 

ecfw vitas do not play sounds with psx games, i really do not know if this has anything to do with the popsloader audio problems on psp go. you get your sound back on psp go when you plug the headphones, not on the ps vita.

what i really wonder is how sony succeeded to make cdda psx games work with full audio on pops for firmware later than 4.01 (which are known to ignore the cdda). i can't extract the .bin/.cue from the psn eboot.pbp to take a look.

any info on how to get .bin/.cue from official sony pkgs/eboot.pbps would be appreciated.

 

I think there's tools to do that now, the PS3 hackage exposed the container format completely and now even the signing keys for the PS1 emu container are known.

 

i am using psn pkg decypter for decrypting an official psx pkg. i get an eboot.pbp but i can't decrypt it to .bin/.cue. i normally use psx2psp for that, but it doesn't work for official eboot.pbps i have. neither the popstation works.

anyone have a way to get .bin/.cue from official decrypyted eboot.pbp files?

 

Yes, there's an old DAX tool. But if IRC the output it's an useless .ISO format.

 

If the feature was never used because CD-DA is always replaced with AT3, then it makes perfect sense of Sony dropping support for uncompressed audio. But it's not what I was trying to point out, which was about Popsloader rather than the emulator itself. Sony wouldn't drop a required core feature, meaning Popsloader has nothing to do with it.

 

thanks, can you please pm me the full name?

 

i really don't know about that. probably no cdda (i mean real cdda not at3) psx games were released on psn, and it became a feature only used on home made psx eboots so sony dropped that. seems logical. though i have to analyze the contents of the psn released cdda psx games (rumored to be at3) to be sure on that but i lack the proper tools for now.

 

Why PM? don't worry, i'm not stingy like some users on this forums that hide info via pm's
The name is PSXdecrypter

 

I think that kind of behavior has more to do with some forum policies about piracy than users being stingy about sharing information...

 

no, im not refering at those cases

@reprep: I beg you, let us know what comes out

 

I would assume the CD-DA support was built in because of the code legacy from Virtual GameStation.

 

as requested, here are the latest news. Yes it is possible on latest firmwares without POPSLOADER with CDDA Enabler plugin. Have fun.
