Nice idea.Do you have any knowledge of programming languages?

 

@george77, i dont have any programming knowledge, but I posted that becuase i want someone that knows how to program to try and see if my idea works. programming is a language, anyone can learn even me, i'm studying on it but i am not a pro i'm just a beginner, ideas are hard to find.

"so from wat i can establish here, the only problem now about getting it to work on DVD9 with swap magic is the PTP/OTP problem. this is by-passed by some MOD chips allowing the console to read OTP, correct? would it be possible to extract the data from the MOD chip and incorporate this into a program that you load with swap magic, and then load the game... same idea as cogswap; or is it the actual hardware of the MOD chip that allows the OTP read function?"

check the top of this page, i already suggested this, apperently its the firmware that does the trick.

 

@gtr2005, no the mod chip itself cannot play the dvd9 backups, but if you update the firmware to the toxic os then it can play it, so what we have to do now is to get the toxic os and make a sort of patch trainer, so whenever you load the game it always goes to a screen where you select to either enable or disable it, and if it needs to save the patch somwhere then you can save it on the memory card. dms4 can have it updated by using the toxic os because the cache of the dms4 is 2MB and its large enought for the toxic os.

 

Sorry for the negativity here, but some of you are being really inconsiderate to swap magic users...
saying stuff like " i think we should now give up "
just because you have got it working using your mod-chips why give up?
sure, you are main priority to yourself, but we are to ourselves, and we helped you, so why do you find it so hard to help us??

i think the ToxicOS idea could work, if someone could try it, that would be great

 

I agree with Kingsizer. Dont Be selfish

 

@Kingsiger and all swapmagic users
I agree with your take care os magic swap users...I'm one of them.
Could you confirm me a dvd DL copy of GT4 with swap magic doesn't work?
Thanks!

 

i've been trying to follow this thread since page 6-8, but it grows so much when i'm not on that i miss some stuff.
what was the difference in layer 1 and layer 0? i thought i read that they were the exact same in an editor only one was somewhat bigger.
would one be able to just burn the smaller of the two?
correct me if i'm wrong. i may have missed something.

 

No DL media will work with Swap Magic. SMD will read the first layer and record that as the TOC size. In other words, it can't recognize the second layer, just like some HD programs can't understand calls to the second layer (which is why the images need to be flattened).

Dasha74 is currently working on looking at both the flash code in the Actel board that the DMS4 uses to try and figure out exactly what the Toxic BIOS is doing. Also, he's giving the new HDAdvance a look at.

A DVD5 solution will not become available to Swap Magic users until the table in the CORE file becomes decrypted. Once again, this is NOT a programming task, so stop talking about it. It has to deal with encryption, and unfortunately, not every programmer is good with decryption (Actually, most never work on encryption, EVER in their programming courses)

However, if you're talking about a program to be loaded off a DVD9 with Swap Magic, I actually don't know the feasability of that. It would require knowing how to trick Swap Magic into accepting it, and then writing a loader that could work with DVD loader, possibly a patch that people can make. But still, it's an insane mess of a matter to even be considering.

For now, let's just hope someone can decrypt the table

 

I'm stating the obvious, but my 1:1 copy I burned through DVD Decrypter worked like a charm!

 

whats the best patch making software for ps2?

now unless your talking about burning back the ISO to dual layer it might change to OTP...how and why,i don't know,i'll pull out a non working back up of GT4 and have a look.

 

@samuels: You don't get it. The original disc is PTP, as stated by the dvddecrypter log you posted, but DL burnable media is OTP.

 

Am so happy i had to post Got GT4 working on the hdd, Lovely ;-)

 

@samuels: You don't get it. The original disc is PTP, as stated by the dvddecrypter log you posted, but DL burnable media is OTP

 

samuels, the ptp/otp are the checks. the toxic os bypasses those checks, when you play the original game it checks the other layer and it finds it because its ptp, but when you play the backup it can't find it because it is written in otp and even if you set the layer break as the original it would burn it in reverse because thats how otp works, it burns the first layer in from center to the outer then burns the second layer from the outer to the center again. so what we all need to do is to try and get the toxic os and make a patch to apply onto the image. gt4 plays the game with the toxic os 100% because it is on the modchip, now i'm thinking if you apply a patch to the image, it would load it up but where is it gonna save it, can it save it in the ps2 memory or memory card.

duh..... *L* iv'e been trying for weeks too at gt4,it never occurred to me,to engrossed in this i suppose...one of my xbox's has a duo 2 chip and it can read d/l no problems,although i think it has been flashed with an executor bios,i didn't do the install,butttt my other xbox,i don't know what chip it has in it,all i know is, it's fairly old,it too plays d/l backups no problems,now i know there would be a difference between PS2 and xbox bios's,does anybody know if the duo2 is flashable for the PS2 to play d/l,although personally i don't think the chips are entirely the problem,but just thought i'd mention this about my xbox's and ask if there was a flash for the duo 2...duo 2 se chip for the PS2

 

@samuels, let me make it clear, the dvd checks are the ones where the laser goes from the first layer to the second layer, if it finds the right data then it loads up, but when you burn it on your dvd writer and because it doesnt write it in ptp it writes the second layer the wrong way, now if you put that into your ps2 it would load up the dvd but when it comes to checking the other layer thats where it fails because it cant find the right data because of the otp. you even said it on this thread that you copied the disc onto a dual layered disc and you didnt change anything or apply any patches, when you loaded it up it loaded the first layer of the game and then it would not load the second layer because its in otp mode, you put your original disc in and it worked because it found the data that it was looking for. I analysed both of the .VOL files the GT4.VOL and GT4L1.VOL in a hex editor and found out that both of these files has the same hex codes but what i believe is that these files are actually one file altogether but split into two. Anyway forget about the PTP or OTP issue the only thing we can do to make it work on a DVD9 is to try and find out whats in the Toxic OS and try and make a patch out of that. There are other modchips that support DVD9 DL like O2, Matrix Infinity, we can get either of their firmware and analyse it and try and make a patch for the actual image.
