PSIO Supposedly Working

lets talk in PM??)))

 

Not all game can be patched

 

so in this case only info from SubChannels hepls?

 

Can you give example of such games?

 

Lucky luke western fever, italian job, jackie chan
But there are others games.

Only working format are clonecd and alcohol images.

 

You sure? i found the following:

Jackie Chan - Patches available for US, Euro and UK versions - protection patches
The Italian Job - Patches available for UK release - protection patches
Lucky Luke Western Fever - PAL/NTSC patches available

 

Im helping too much this guy
btw jackie chan ok
ita job only uk ONLY it's avaiable, other region are unpotected
lucky luke- pal\ntsc patch it' NOT a protection fix.

honestly a device that can support only .bin it's totaly useless.

 

i remember Ja-Chan feeze sudenly in random moments)) it's good to hear that problem is not in hw))

i dislike patches, but if it's easy way, why not.

current hw/sw support only .bin, but it's not problem support other image types)) ccd.img is same like .bin , only additional .sub.

 

Not because bin format have big issues with multitrack.
Random freeze it's not made by libcrypt

 

if you read my post properly you will see that i know Lucky Luke doesnt have a protection fix, thats why i wrote protection fix's next to the other 2 but Pal/Ntsc on that one, also i know that Italian Job is UK only, thats why i wrote "UK release" next to it

 

AGAIN
Lucky lucke wester fewer PAL like other inforgrames games
Italian job have FR DE IT and other languages relese.
But there are lot other games that arent avaiable patches.
Games like FF 9 (some pal relase)
Also not all patches works at 100%. Like FF8 (all pal relases)

Editk, languages incromprension, on lucky luke you're right

 

As it was said earlier: subchannel data is not big deal, don't focus on it, it will be implemented later.

 

yeah i think our wires got a little crossed - sorry if i caused offence

 

I think you never know what you are talking about
It's not even question of subchannels, but don't focus on it, PAL games an multitracks comp. games
isn't important.
hehhehehehehe

No problem, sorry

 

You're confusing me - most of this discussion was about support for LibCrypt games - and that absolutely does involve subchannel support. The way that LibCrypt hides the keys is by embedding them into part of the Q subcode channel and then modifying the CRC so that the player will ignore the data but the LibCrypt code can recognise it.

 

so what is LibCrypt - software or hw ? i remeber one good guy/man told about on his site - ps1 call cmd 11 (GetlocP) and answer/response should be location based on subchannels. but there are some subch-ls with wrong addreass and program knows where it should be and than use it to gather bits for key. ??? or it works something differ?

 

It's software - it's a form of copy protection added to (mostly EU) playstation games. The basic way it works is that certain sectors are written on the disc in encrypted format, and the key is stored in the subcode data. When the game starts up, it reads the key and stores it - then later on when one of the encrypted sectors is wanted this key is used to decode it - if it's the wrong key, then the game just crashes.

The other fun thing is that they stored the key in one of the COP0 breakpoint registers - so if you attempted to run the game under a debugger and use trace mode then you corrupted the key.

 

You should really go and learn subject before bullshitting others here.

I never said that multitrack games aren't important.

 

I was talking about clone cd or alcohol format.
I don't shoot bulshit either i don't write stupid reply about ignore this and that and continue because something i don't know it's not important. I KNOW what i write unlike someone.
If i reply, i reply because i want help, but i think i'm helping too much this people.
Libcrypt XORED key it's contained in Q subcode (nothing crypted) in form of false CRC, ergo in subchannel info. So bin it's useless for psx format.
Also .cue (and .bin) can't contain important info about multitrack games, so it's totally useless like the redump data info.
Who developing this project must study more and more about psx and image format.
So i'm stopping right here

 

Look, you've accused me, then TriMesh pointed out you're wrong, and you're still saying "I KNOW what i write unlike someone"?

You even don't know a thing about CUE. CUE sheet can contain arbitrary count of tracks. Data usually defined as *.bin, Audio CD tracks are put into WAV container by ripping software, but that's not mandatory, you can still export audio tracks as *.bin. This is common format, and this is format most widely used in preservation. Often Neil Corlett's ECM utility is used to compress data tracks. Subchannel data can be preserved for these 10 games which are using libcrypt, end of story.
