Shrink PS2 ISO
Remove dummy files form PS2 ISO
Installing PS2 games to Hard drive.
PS2 / Shrink / Remove Dummy files /

I was looking for a way to remove padding files from my PS2 games so when i pack them on my hard drive the padding files aren't taking up needed room I saw lots of topics on dreamcast but not much for PS2 so I'm adding a PS2 post for search results.

The example game used is Soul Caliber 3, this may be different for other games or may not work at all....

Looking in the PS2 sections where it should be and i'm not seeing it so its either buried in a thread as a reply or in a wrong section or possibly even just i have not gotten to it yet the sites being kinda slow.

I'll be cleaning PS/PS2/PSP sections first so i plan to update and add whatever seems to be missing.
From now on i want to sticky good topics so they stay up top.

Most of the time you can open the iso in UltraISO and delete the dummy files. If you look at my uploads you'll see that I uploaded a lot of PS2 that have the dummy data removed.

Most dummy data is named, DUMMY.BIN, DATA0.BIN (or .DAT), DUMMY.DAT, and a lot more. Also sometimes the dummy data is in a folder named "PADDING" and other folders as well.

If you not sure if the file or files are dummy data, you can try opening them in a Hex Editor and see if the file is full of "00 00 00 00 00 00 00 00 00 00 00 00 00 00" only 00s but sometimes dummy data more then just 00s. ie: .Hack//Fragment

gon hijack this for a little. what does a Dummy file do? googling tells me its just random garbage data used only to increase ISO size, and/or allow better data loading. what's it really for and why is it needed?

@yosimba2000 - Yeh dummy files are used to push the data to the outer edges of the disks since theres longer data feeds it reads faster.
If you removed the dummy files and then burned the disk it would burn it all to the center and the laser works harder to read it and possibly lag.

@vash32- That might work sometimes but not always some disks require updating the TOC and LBA on the disks and will not work right if not updated... also u can change the size of the file to 0mb on some to prevent messing with LBA and TOC.

Not exaclty , it could have different name and also maybe not be filled by zero.
Plus remember that also some audio and video can be riped , especially those who are in a language which you do not want.

In the case of soul calibur 3, I just copy the files to a folder and delete the file PAD_0.DAT and make a new iso with ultra iso.

Always check the data of a "Dummy" as some are not dummies ! (Hexedit)
They contain active data, without disk image will not work !
Very rare this happens but....Compiler Programmers little joke
