Released: YAUIS: Yet Another UMD iSO Shrinker v0.3 (BETA)

Ivan · 17 Agosto 2005

Nuova versione di questo utile programma che fa uno scan di un qualsiasi gioco per trovare metodi di compressione o di taglio al fine di rendere la immagine o il gioco stesso meno pesante possibile in termine di KB. Come risultato alla fine crea un file in formato .ISO pronto da usare con Fastloader o a proprio piacimento. Due aggiunte importanti in questa nuova release, scopritele nel readme qui di seguito; troverete inoltre il programma in allegato e nella nostra zona download.

YAUIS: Yet Another UMD iSO Shrinker v0.3 (BETA)

This program is all automatic : it scans the dirs, the files, and build a new iso of the smallest size possible all by itself.
As I had no clue how an iso file layout worked, I guessed it by myself and, well, there *might* be some horrible bugs in the directories/files scanning which could corrupt the shrinked iso.

The program has 2 options, which should not be useful at all... :
1 - "Keep the 'minimum file padding'". For some reasons, some isos have their file position padded to $8000. Checking this option will keep it that way.
2 - "Pad the ISO to $8000". Not really sure why I added it that way... Might be useless. But some games seems to have loose sector at their end, and Isobuster seems to need it to...

So here is how it works : drag and drop the iso on the program, wait for the 'Done' message to appear, and voila. The newly created (and size reduced) iso will be created in the same directory than the original iso file, and it'll be named xxx2.yyy (where xxx.yyy is the original iso file name).

I've got no problem with it, but I only tested one game on the PSP (which worked of course)... So don't hesitate to post if you find any problem with it !

PS : Some games won't work after being shrinked (Hot Shot Golf, Taiko no Tatsujin...). They need some other specific changes which can't be automated. So don't use YAUIS with them.

Changelog :
---------

v0.1 :

First release.

v0.2 :

- Corrected a bug in directories handling (thx Nosferatu).

- Added a 'Select Destination Directory' button. When you click it, also enter a dummy file name to validate the directory. However, the outputed file name (of the shrinked iso) will always be xxx2.yyy (where xxx.yyy is the original UMD iso file) (BaNDiTo_RoX).

- Added a 'Dont move 1st file' button. Not sure if it'll be on any use, but it's just in case (ie. if a shrinked iso doesn't work without this option, checking that option *could* make it work).

- Corrected a display bug with the application title (the 'ISO' word would disappear after a shrink has been done).

v0.2a :

- Made that the program now recognizes vcdromX created isos (althought it seems to not reduce the size as it's already at its minimum).

- Now the program correctly updates the new .iso size in the shrinked iso file.

- Corrected a bug in the file saving path handling.

v0.3 :

- Added a 'Shrink !' button. You now have to press this button to launch the shrinking process. Once the 'Shrink !' button has been pushed, it'll be disabled until you load a file.

- Added a 'File Editor' tab. When you drag an iso on the program, the iso contents will be listed there. You can then browse the files (double-click the directories to 'open/close' them). Left-click on a file, and its name, size and LBA will be shown at the bottom. Then Right-click on the same file to bring a pop-up menu with 3 options : 'Delete file(s)', which will make the selected file (or all the files in the selected directory) have a 0-byte size (use it to remove dummy files) ; 'Copy Size and LBA' which will copy to memory the size and LBA of the selected file ; 'Paste Size and LBA' which will paste the copied size and LBA on the selected file (use these two last options to relink files easily ; these options don't work with directories). Of course, once you've made all the changes you want on the 'File Editor', you MUST press the 'Shrink !' button to apply them.

- Some other minor changes/fixes (I hope I didn't break anything...).
