Hacking Wiiscrubber 1.2

[Deeptrap]

Very great tool, but a'm testing right now kidz sports icehockey, and it says 76 MB Scrubbed with keeping the header,

is this correct ?

 

[Dack]

Finally back on t'internet!

The header calculation is not included in the file size so you are probably going to be looking at an extra 300 meg on top of that if you keep them.

Smallest at present seems to be a wiichess with the headers and brickblocked that comes in at 26 Meg - a lot of the ddi games (and I believe kidz sports is one of them) come in at 100 Meg or so.

Thanks for the new version Dack

I think i've found bug

I'm modifying Okami's ISO and i need to reinsert a 2GB file, but it tells me

error in memory allocation
Error in replacing file

i think that this is beacuase i have only 1.5GB of Ram but, could be fixed, maybe working on HDD if the ram isn't enough?

 

[Edgedancer]

I would just like to ask a question. Since this new release of wiiscrubber uses trucha, does this means that the games will not work when the IOS37 firmware come out?

Thats because of the current file load implementation - it reads it all in before trying to write it out. Maximum memory allocation using malloc/callocis a signed 32 bit - or about 2 GB.

The replacement code it very inefficient at present and is currently being worked on (when I get a spare moment

) - the newer version replaces upto 64 * 32k chunks at once - meaning the memory requirement is then a lot less. It's also a LOT quicker. (And has a progress bar!)

IOS37 is already out - just not used at present.

Any game modified using the trucha routines (LOAD, TRUCHA Scrub) could be affected. The 0xFF Scrubbing does not alter the H3 table or the signatures - much like the original release.

Hi Dack,

I thought this new version could help in getting rid of the mising .DIF files I can't find anywhere but I should have miss something.
wiiscrubbed Compressed ISO without .DIF associated DIF file is useless, correct ?
Is there a way to downolad such files somewhere ?
Thanks

 

[Edgedancer]

I guess my main worry is that by downloading scrubbed releases, they will be trucha scrubbed and as such, not work when IOS37 is put into play.

Wrong. They burn and play perfectly fine.

Good news then

, but what am I doing wrong ? I have the compressed ISO, I open it with "Unscrubbed image" button and then it always ask for a .DIF that I haven't so it ends
Thanks again for your help

 

[SleepyPrince]

you don't need to use WiiScrubber before burning a compressed ISO, just burn it like you would with full release
the .dif file is only needed if you REALLY want to restore the game back to full release

 

[solo888]

Thanks a lot !!!!

Long life to gbatemp !

Sleepy, any luck getting it to work with PAL Wii Fit?

I bought the legit version (PAL Wii, PAL wii fit) and think I have an old WiiFRee installed (not sure). Bizarrely it worked once, played it, synced with board and all was fine. I quit out and now that exact same disc can't be read by my Wii, neither can the original disc. In fact, the drive doesn't work again until I reboot the Wii, then all is ok (backups and originals) except for the Wiifit disc and copies (they all cause the drive to spin and become unuseable until a reboot).

I know the simple answer is to just get a better modchip but having successfully played the game It's frustrating to think I can't get it working again.

 

[SleepyPrince]

I am not very familiar with modchip
afaik legit games shouldn't have problems with modded wii
I dont know other solutions except changing the modchip

Or just download the ISO for the game you bought and paid for. Technically illegal, yes. But ethically 100% ok IMO.

Dack, great work. I have been using this for my Guitar Hero 3 customs that have files too large to replace with trucha. Works great. I have one question though, on the root of the data partition, there are some file that don't show up with your wii scrubber. Trucha allows you to see the and extract them, but not replace them. The specific files I'm interested in are tmd.bin and ticket.bin. I'm trying to edit the 4 letter game code to force a game into using a different save slot and I'm fairly sure those are the files I need to edit. I have extracted them with trucha and edited them, now I just need to re-insert them. Is there any way I can do this with wii scrubber? I don't know why trucha doesn't let you. Thanks.

 

[Dack]

It's because I don't actually allow that at present.

The files are contained in the file I call partition.bin. That represents the first 0x20000 bytes of the partition before the data starts and contains the tmd.bin, ticket.bin and the h3 table. As that data is changed when the files are altered it seemed a bit pointless allowing them to be changed.

The game code is actually in boot.bin I believe. (it's in the first 0x440 bytes of the image)

 

[Kor]

I tried editing it in boot.bin, no luck. It still loaded with the original save.

 

[lolsjoel]

Not to bother you too much or anything, but what's the word on the next update of WiiScrubber? I have a whole bunch of files I need to inject into an ISO that are larger than their originals, but at this point it takes almost 10 minutes per file to replace. With a few dozen of those, this could take a ridiculously long amount of time.

I'll be looking forward to that release

EDIT: Does the file replacement feature work at all in WiiScrubber 1.21? I'm working on a custom Guitar Hero disc and tried to replace Hit Me With Your Best Shot with a song that was larger than it, but when booted up, the disc froze while hovering over that song. Something definitely went wrong. The replacement took nearly 10 minutes, it said it was successful and then reparsed. After that, I guess I just closed WS1.21. I didn't know if I was supposed to hit the Clear and Save ISO button or not. Either way, I added another file with Trucha Signer right after that, so I use TS to sign the partition. Any ideas as to what went wrong?

 

[Kor]

I haven't tried audio files, but I have used wiiscrubber to put a qb.pak.ngc that was larger than the original. It worked fine. It took a while but not 10 minutes.
