IS GT4 HDloader/HDAdvance combatible?

Nonono, the idea is quite good and works in theory. You only need the HDL / HDA disc to boot the Loader, once it has booted up you can swap the disc to the GT4 original one. I haven't tried this myself, but people have, and they say it doesn't work. It kind of nukes the idea of loading the game from HD only anyway, like Slick6 said.
 
@dragonmaster
I didn´t read your postings very well. Now i´ve read that you tried the things i mean before. I only got a little hope when i see that the image floating around has the wrong format.

I tried now with regular ps2 tools and get the same results :(
PS2 is not my firsttime hobby, i had to try it by myself to understand.

Ok, we have to wait for a patch.
 
Honestly, its a dream playing GT3/GT4P/GT4 Demo on HD Loader.

The load times are lightning fast and there is no wear and tear on the laser.

In good time I am sure some people/person will get the game working from HD once the protection has been defeated.

Seems like PD went all out in this though.
 
Strange...if it's this easy to make a game HD incompatible, you have to wonder why Sony decided to stop making the PS2 (I thought one reason was to phase out the hard drives?)
 
Is there any way to do what was brainstormed in post #23, in this thread.

One person got it working from HD by swapping in thier original game (look at post#1 & #22). Could you burn to DVD5 only the needed portion of the GT4 disc, and run the rest off of your harddrive? I haven't heard this idea yet and don't know if it will work.

Using this method will at least cut down on the use of your elderly laser in the PS2. That is, if it works.

Any ideas?
 
Some information was uncovered by someone on another forum:

Something else, I loaded the file SCPS_170.01 (that is an elf file) with InLink, weel it's the same way of booting than when I boot it from HDD (It launches the ps2 CDVD drive ), then I looked into more an I can see that it is calling CORE.GT4 and also IOPRP300.IMG those three files are linked, the first boot and call the two others who are in interaction.

Then I looked into IOPRP300.IMG here's an extract :

fileIO SEEK

CDVD: ReadDvdDualInfo Read Error %02x, %d

So I can only guess that the layer checks are here somewhere in this file and maybe there's some in CORE.GT4 but i've only seen things refering to menus, internet connection, car names etc...
and that this is one on the reasons why the game won't boot.

It's "asking" to change layers :crazy: :dopey:

Quite interesting don't ya'll think?

There should be a way to flatten the info so it's on big side, and take out the change layer check thing, so that it reads the data all at once.

Yeah, the layer check is the only thing preventing the game from booting from HD because if the game was incompatible with HD Loader etc then it wouldn't even reach the disclaimer screen.

All the other Dual Layer games didn't have a layer check.

Smart move Sony 👍
 
Should be able to hex edit that check out, possibly?

I have Champions of Norrath but I don't know how this TOC refresh works, anyone any pointers? I'm sure it won't work but I haven't read anyone here trying.
 
ARWIN! I think I have figured it out after a few hours of scouring the internet.

To refresh your TOC you need to insert your CDLoader 3.0 disc. Then when it boots up and says insert disc. PRESS EJECT, the screen will say something like insert TOC refresh disc or something, then insert Champions of Norrath, your ORIGINAL version of it. It will say "refreshing TOC" or something and then "insert your program disc". Then you use your fliptop like normal and pop in the disc.

GOOD LUCK!

that's what i was thinking. seems like that could be eliminated or edited somehow?

i how someone makes some headway soon on this.
i'll order an import in a sec if it can work with my HDD. i don't think i can hardly stand another 6, count'em, SIX more long weeks. :scared: :scared: :crazy: :crazy:
 
also, what happened to the guy that said he got it to work from the HDD WITH the original disc?

Did he just dip in & say "I got it to work" & dipped out?
 
i think its possible to rip it on a dvd5 just by ripping the intro movie end the credit movie


but but make it is harder than say it

still waiting a dvd5 release
 
anyone know the total size of the songs ? if it can get ripped to a dvd5, then many people can get swap magic and play without any modds to the ps2.
 
I think the big deal as to why no one has edited the hex, or the songs is, they have no way to extract the .vol file yet. Not to mention taking all those files and redirecting all of the commands pertaining to that file (because of the different location/all that garbage of ripping/downsizing), is a huge task.

Even though there "are" ways to do it, I have heard no info of anyone actually trying to decrypt the game file and the like. There have been people dabbling around, but the regular old GT3 extraction tool won't work for GT4, so someone has to develop a way to extract it.

I WOULD put in the time because I have some to spare, but I also have very little basic knowledge of programming, the best I've ever done is a partially working ping pong program for a TI-83 calculator. I have no idea where the person with the knowledge would be, but it sure looks like they haven't shown their face in this thread.
 
If there was a method to unpack the VOL file, the easiest way to get rid of large amounts of data would be replacing the music and the videos with small dummy files. If you take the same file format as the original file, the game wouldn't even notice, and you could probably save enough space to get the game onto a DVD5. The problem I see is that the layer check must be removed, cause it would let a DVD5 fail, as there is no second layer.

And if the layer check was removed then we wouldn't need to downsize it, because it "would" work on HDloader.


So, here's the list of things to do:

1. Unpack the VOL files for GT4. The method for decrypting the data should be in SCAJ_300.07 file (<<<that is according to another GTP'er I believe)

2. Remove DVD9 layer/disc checks. That would be hex editing done by a talented hex reader and programmer, and made into a handy ripkit for all to use!
 
Flattened my image (Taken from my original Chinese DVD) from dual layer DVD9 to a single layer, put it on the HDD (Via HDL_Dumb over USB in HDD Caddy), and then run HDLoader with Original Chinese GT4 in drive (Mode 3 set). The game runs completely off the DVD.
 
actually if u succeed in removing the dual layer check the rest is easy....

1/ copy all files to hdd and verify that there is 6.5 GO of files
2/ remove the dual layer check
3/ rebuild with sony cd/dvd generator as a single layer one
4/put it with hd loader

...good luck -hopeless for noobs-...


PLZ iwanne release.... :nervous:
 
if you leave the gt4 game disc in , that should eliminate the problem with the layer check. Since swap magic 3 has a TOC refresh, u may be able to use another dual layer dvd like champions of norrath, which is over 7 gb. ill be sure to try it when i get it.
 
Ah maybe my messsage wasn't very clear. It doesn't use the hard drive at all (As claimed on another post), it still remains to run off the DVD. BTW my PS2 is a 30003 UK version with a Messiah 2 chip.

I think the key to fixing this is to remove the dual layer check, which is well beyond me.
