Sony ATRAC3 Audio Codec

[Witcher]

anyhow most non legit users will be disappointed since alot of games are encrypted and you can only decode them on a real PSP

I'm totally uninterested in PSP as console...It never amused me or catched my interest.By the way,good thing is i want to try Crisis Core only,and on my luck and others,it isn't encrypted
And as i said,it would be a waste to buy a PSP for only one game(in my opinion).

but the biger problem is for some who dosent have the money to buy a PSP, and they turn to emulators.

You are right,i said that previously too.Not everybody has money to buy psp...

Playing a game isn't an obligation. If you don't have the money, you don't play.
That's how it works now.
It's true you can play on the emulator some games, but a PSP is much more than what we do.

i found the xreader and lightmp3 player for the psp which plays aac3plus

but i think at3plus is hardware decoded by the psp or?

[Orphis]

It only works on a real PSP. It's no use for us.
And stop saying you've found something new. There is NO open source solution to decode Atract3+ without special hardware yet.

[serio]

another good reason to use an emulator over the actual hardware is, when you try to extract some graphical data from it, or to study in closer detail how does a game work. you can't do that on the psp's small screen and you don't have any additional options such as pause whenever you want, debug options etc.

taking screenshots, making videos and extracting graphics is almost impossible without hacked firmware, and even that one's very slow for that.

I found this about ATRAC3plus if it can help you : http://wiki.multimedia.cx/index.php?title=ATRAC3plus

i have one question about the whole atrac3 thing. is there a problem with decoding the normal at3 files?

from what i can see the at3+ files get decoded and play better and better, but regular at3 music is still as silent as it was ever since i tried the emu for the first time. just wanted to know why. (note, i can decode that music with external tools like himdrenderer + sonicstage so i don't think decoding them is a problem).

There's this post that i've found, the guy in the last post claims he can convert oma files using ffmpeg.

As we are using ffmpeg in jpcsp maybe we could implement it but i doubt unlike the sony codecs [atxdec.ax and atxparser.ax] it can play all types of non-drm oma.

The ffmpeg method is the method that is probably used by vlc media player.

One more thing is that the code is for ubuntu.
