Accessing Memento Patched Disks and DVD Videos

[ghostboy78]

I have been recently trying to access the files on memento patched DVD (looked at as DVD videos?) on uLaunchElf and I can't seem to do it. Is there a certain module that supposed to be loaded in order to read the files off the disk? If a module is not being used to read the files from a memento patched disk, would I be able to write a PS2 proggy that could do so? Can anybody explain to me why DVD-V disks can't be accessed?

No, there is no module dedicated to reading the DVD-Video format. It ought to be handled by the same CDVD lib which implements other CDVD access, but the 'libcdvd' used by uLE does not currently accept DVD-Video discs.

If a module is not being used to read the files from a memento patched disk, would I be able to write a PS2 proggy that could do so?

That is possible, but very demanding to do from 'scratch'. An easier route would be to modify some existing lib module to do it.

DVD-Video discs use a different filesystem than normal data discs, and the current CDVD libs of uLE will not accept such discs. We plan to change that for some future uLE release.

@dlanor:

When my modchip is on, I am able to see the contents of my DVD-V as well as memento patched DVDs. But when it is off I cant. Do you know why this sort of behavior happens?

isn't this because your modchip is on?

what i meant yoshi was that if the cdvd drivers of ulaunch couldnt read video dvds, how do we see the contents? Like I thought the modchips were only used for the cd/dvd validation process and not reading/listing contents etc...

is it not possible to 'reuse' sms's features on launchelf?
sms > launchelf (maybe no iop reset) > browse dvd video
i dont have a working lens so i cannot try it

Thanks for your explanation. I'm going to dig deeper into this some more today.

Try to embedd atchuss's unofficial (Neme-)Loader v3.

http://rapidshare.com/files/12078156...er3_mcload.zip

Changes:
- If you start pressing R1 then the program runs "mcX:/BOOT/R1.ELF (if exist)
- If you start pressing R2 then the program runs "mcX:/BOOT/R2.ELF (if exist) 
- If you start pressing L1 then the program runs "mcX:/BOOT/L1.ELF (if exist)
- If you start pressing L2 then the program runs "mcX:/BOOT/L2.ELF (if exist)
- If you start without pressing R1,R2,L1,L2 (or the elf don't exist) then the 
  program runs "mcX:/BOOT/PS2.ELF (by default it can be the PS2Browser.elf to 
  emulate memento)

[ghostboy78]

How would I go into doing that?

[TnA]

Use Free MCBoot-Installer v1.3beta, rename "loader3" to "BOOT.ELF", place it in the same directory, as FreeMCBoot 1.3 Beta and start the installer.

Launcher 3 will be embedded to your OSDMAIN.ELF, along with your DVDELF from rom, or your DVDELF.BIN, which must be in the same dir, as FMCB-I.
Also a more comfortable way, to load ELFs, with Button-Start (NoMod-Users will love it I think.).

When you refer to "loader3" are you refering to "launcher2.elf"?, casue if not I can't the file you are talking about. But I'll try it anyway.

[TnA]

No,... Loader 3 by user atchuss.

[unclebob69]

I also only see launcher2.elf. their is no loader3 in that rapidshare link

[ghostboy78]

I think you uploaded the wrong launcher since it says "launcher2.elf".

[TnA]

Has it the same MD5-Hash? :P
Open it. The modified src is included.
If you didn't even try to run it and configure it as it was told by atchuss, then your just a flamer to me, cuz you talk about things you have no clues about.
Atchuss just didn't rename it, or I'm very far away from topic, if (Neme's) loader2 will start PS2.ELF automatically, if it is in BOOT-Folder.

[ghostboy78]

Alright, I went along and embedded the launcher, placed uLaunchElf renamed to "PS2.ELF" into my BOOT folder, restarted my ps2 and all I have is a black screen

[moditripit]

I don't see how this is allowing the use of patched Memento discs, but I see that it resembles the memento style of booting (hold a button to launch an app).

Anyway, I renamed PS2Browser.elf and called it PS2.ELF and renamed ulauncher.elf: R1.ELF and put them both in MCX:\BOOT\ and it works perfectly WITHOUT a ps2 game in it.

It will hang on a black screen if I start it with a PS2 game.

Another note, I somehow managed to get in an infinite loop of the ps2browser loading over and over again when I loaded ulaunch by holding R1, put in an original PS2 game, and loaded ps2browser.elf through ulaunch.

This is on an unmodded NTSC V9 SCPH-50001.

[Sh@man]

It is possible to start dvd game not original on ps2 if is free mc boot?

[TnA]

If you embed atchuss's loader 3,... Maybe.
I couldn't test the memento-disc-support because I have no WinOS and no Memento-ISO-Patcher.
Can someone give me a hint on this?
