Huh, magumagu's old partition fixes... If it breaks SSBB specifically, it's probably because ISOProperties now also scans for groups, which only SSBB has more than one of. I don't know why that causes a problem with WBFS, but maybe PR 2353 affects it. Please try it out: http://dl.dolphin-emu.org/prs/pr-2353-dolphin-latest-x64.7z

Tried that link, still getting a unhandled exception error.

I even tried on on two different PC's

But they're mine and have similar configurations. Are you able to open properties for SSBB when it's in WBFS on your setup? Like right now?

I suspected it was because of .WBF1 but that's not the case. I can open Xenoblade Chronicles and Metroid Trilogy which have .WBF1.

I've never used WBFS before. I'll convert my SSBB ISO to it and test when I get time, maybe this weekend.

Okay, great

Possible culprit is that ISOProperties (something you mentioned earlier) ignored .WBF1 (game is divided into WBFS and WBF1 when it's more than 4GB). It might only focus on one .WBFS and that's it. I can imagine the disc image will appear to be corrupted when .WBF1 is ignored or not found.

When I merged WBFS and WBF1 into one whole WBFS (just by "copy /b RSBE01.wbfs + RSBE01.wbf1 full.wbfs" in command prompt) Dolphin can read it, and properties window still can't open.

So WBF1 is not the culprit apparently...

I deleted full.wbfs as it was just for testing.

I converted WBFS back to ISO (thanks to wbfs_file.exe by kwiirk that I can simply drag'n'drop to convert WBFS to ISO and vice versa), Dolphin can read it, and now properties window can also opens properly.

Then the interesting part is, when I convert it back to WBFS (WBFS and WBF1 like usual), properties window opens OK.

Which program did you originally create the WBFS disc image in?

I used USB Loader GX on Wii

It will rip Brawl disc as WBFS and WBF1

I think I was mistaken about properties window able to open Brawl that has been re-converted back to WBFS. Maybe it's actually ISO. I removed path in Dolphin settings so I lost track of it.

I mean I perma-deleted re-WBFS and re-created it to make sure, the error came up once again, hence I lost track of it.

So the error always appears when you are using WBFS?

For Brawl yes

Every other games no

I couldn't reproduce this when making a WBFS file with Wii Backup Manager, but I could reproduce it using wbfs_file.exe. For some reason, the file system code gets an abnormally large size of the FST in the first partition in the second group, and then the exception occurs when it tries to allocate that much memory. I still need to investigate why it doesn't get the right size, but PR 2610 should work as a workaround: http://dl.dolphin-emu.org/prs/pr-2610-dolphin-latest-x64.7z

AHH I remember now! I did used Wii Backup Manager in one of my test and properties window brought up.

I am receiving warning message saying it's "Read beyond end of disc".

The masterpieces doesn't work on both Dolphin and USB Loader GX and I have a feeling you will mark it as WontFix. It's disappointing realizing that USB Loader GX and wbfs_file.exe been making bad files.

There isn't anything we can do to make all the partitions work properly, but making it possible to open the properties window despite the partition errors is reasonable. Did PR 2610 let you do that?

I used PR 2610 when I said I am receiving "Read beyond end of disc".

Sorry, I should have stated that before.

BTW the "game" partition is in partition 0 in bad WBFS file while in the ISO file, it is on partition 1, so maybe that explains why PR 2610 tries to read partition 1 then throw a warning because partition 1 is blank. I haven't tried good WBFS and WBFS through wbfs_file.exe.

Apparently the "game" in partition 1 in WBFS still receive a warning. Nevermind about what I said earlier.

Yes, I also forgot to say that warning message is infinite when I tried PR 2610.

This is going to be a great news for users who have been ripping/converting discs/ISOs to broken WBFS files the whole times. Thank you very much.

PR 2712 has been merged, and I've rebased PR 2610 with all the recent changes on the stable branch, so this build of PR 2610 should now be able to open the properties window: http://dl.dolphin-emu.org/prs/pr-2610-dolphin-latest-x64.7z

Confirmed working after several "Read beyond end of disc" warning messages. I (and others) will be fine with that. You did great!

PR 2610 has been replaced with PR 3206. The only difference is that it now is based on master instead of stable.
