I have tested a lot of Scene Releases with this tool and the results can't be foolproof for certain dumps.
I've noticed this problem occures especially with insane overdumps!

For example: 7_Wonders_Of_The_Ancient_World_EUR_MULTI5_REAL_PROPER_PSP-ZER0

--> would be a shame if a *real proper* is a bad dump. ZER0 usually knows how to dump games and most of their releases are good.

next Tekken_6_EUR_PSP-ZER0

--> I own the UMD of this game and dumped this game on 5 different PSPs with different CFW and different memorysticks using PSPFiler 6.6
I always got the same CRC32 as the scene iso! The game appears also in the Redump.org db with same hashes.

I think this "Wrong Size in Header"-Problem might be some type of copy protection since Tekken 6 uses LBA so you can't make a rip easily.

Here's a snapshot of my "Tests" http://www.mediafire.com/?f34io6kbpsn9wbg. Update is comming soon.

Please have a look at this Mercyful

Thanks, Pisdatko.

Also, all other dumps of Tekken 6 are 816 MB. They have different EBOOT.BIN, PARAM.SFO UMDATA_BIN.BIN only, the rest of the files matches.

Even the languages are the same: english , russian, korean, japanese, french, spanish, german, italian

this can't be a bad dump. there would already be a proper.

i know this bug and it is not the protection problem... it is just a mistake of tool's author :)
UMD Size Verifier successfully detects sizes for about 60-70% of dumps and everyone can use it (it is much easier than any hex editor, is it?).

As you can understand, I don't want to write an instruction for all the users with all the possibles ways to detect real ISO size and we don't have a lot of free space on the game description pages.

As for the Tekken 6. Yes, ISO has lba protected hidden files. All of us know it :)
... but where did you find a bad dump of Tekken 6 in our database?
NOT CHECKED doesn't mean BAD DUMP, it means NOT CHECKED :)
Beleive me, we are doing our best to fulfill a database but we also have a real life, work and families ;)

Here is a fixed UMD Size Verifier: http://www.multiupload.com/UZI6FL1WHJ.

I think it should correctly report the valid size of an ISO now.

By Mercyful Date 2011-10-17 16:02

thanks! will try it asap...

By RighteousPerv Date 2011-11-12 00:25

The fixed UMD Size Verifier seems to work like a charm. I know its an old post, but this felt necessary to let people know.

Any chance of a UMD Size Verifier for Linux? I keep my collection on my linux box. I'd love to be able to check them all, but would hate to have to move them all to a Windows machine for it.

Thanks
