Title: Yet Another Umd Iso Shrinker
Post by: Modiller on August 05, 2005, 03:43:00 AM
Tonight kenobi has released two different builds (just hours apart from eachother) of YAUMIS (Yet Another UMD ISO Shrinker) Instead the 3 steps you had to use, with the ISO shrinker released yesterday this is all automatic. The author will also be away for the next 7-10 days on vacation, which means we won't be recieving anymore builds for the next week and a bit.

Read Me v0.1 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 !

I also plan to add support for a 'file deletion' option, in case there are dummy files in the iso... But I'll see that after my vacations.

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).
