Accessing Memento Patched Disks and DVD Videos

[ytifle]

so, ffgriever you have made a jet unreleased app to, with the help of the mc xploit, load patched memento/yourself/DVD-V ps2 games in any ps2?

tell me yes, and i will shout yeah!

Any known date?

Thanks for the update on your loader. Great work. I have 1 question though. I've noticed that the memento patcher adds a separate udf filesystem with video and audio folders. Will you do that or are you going to just add the extra folders to the existing filesystem?

PS. ESR has nothing to do with memento. It's done in completely different way (I believe better way, since it's already superior in terms of compatibility, at least when it comes to games, it also doesn't contain even a byte of sony's proprietary code, so it's completely legal... plus the size - my solution is 16kB of code in total and only ~8kB on IOP side), and not even single byte of it is based on memento code (written totally from scratch). It still has some problems with some homebrew apps, but it will be fixed in time, I'm sure... You can also exit to browser and start a patched game from there. One thing they have in common is use of DVDV patched discs. I already took care of all the issues, so after some internal testing public beta should be possible.

what are the homebrew issues?

btw. nice job, ziom ;-)

didnt he explain it already?? The ps2 cannot read the exact backup copy that is burned. But it can read dvdv discs tthat are burned. memento patcher, patches the ori dvd backups to look like a dvd video disk... So the patcher is a simple way. U can ofourse create a dvd video disk urself with data files in it.....

Coolaan I understand that much. Maybe my wording wasnt clear, but I was asking if his loader would use memento style dvd video discs where the video_ts and audio_ts folders are on a separate filesystem from the game files or if it would use sms style video discs where the game files would be on the same filesystem as the video_ts and audio_ts folders. It doesnt really make that much of a difference, though. I was just curious

Nice job @ffgriever:

THX @oli for his DVDPLX-Dumps &Tutorials.
I wonder, how exactly Memento access the ISO9660-FS.

@yoshi314
I've fixed most issues with homebrew (even hdloader works fine and you can install games from patched discs, then they're fully playable in hdloader). The only one remaining is that some of them are just trying to overwrite my code (homebrew apps are much less predictable than games ... and I need some resident EE code to catch iop resets on this side).

@EppyK
It can read both... as long as there is iso/joliet structure. But take a note, that some games won't run if you'll move some files (which will be necessary if you're going to add some files/dirs to the iso structure). That's why memento patched discs have all the data untouched... just some basic udf structure written in unused space. Real DVDV discs will be readable as long as they contain iso/joliet structure (depending on method and drivers used... the internal one is working on iso), and most of the DVDVideo discs do contain hybrid udf/iso structure.

@ffgriever
Thats good to know and thanks once again. I was hoping that It would read both since it would be easier to put homebrew on a disc without first making an iso and then patching. BTW will you be including your own iso patcher or will you just redistribute the memento app. I know it wouldn't really make any functional difference, but again I'm curious.

Is the access to DVDV files of those things were its "simple when you see it"?
I hope when it's released ill be able to understand how it works. Sounds tight ffg

Dose ESR have the same flaw Memento has when playing in-game videos? Like for exsample in Dawn of Mana all of the cuts would be skippy, any game with cut scenes like it would have this issue.
