postLoader 3.71.3 doesn't seem to load Majora's Mask using cios38rev17b (in slot 248) - it code dumps and the nb.log file says that decompression failed. I did some looking through the source, compared to Mighty Channels 11.1 (which does work for my setup, but I prefer PL), and found that there's a key difference in Nandbooter's lz77.c:

Code:

if (compressedPos > inputLen || decompressedPos > decompressedSize)
{
return -1;
}

I commented these lines out in both __decompressLZ77_11 and __decompressLZ77_10, and Majora's Mask booted perfectly. Are these lines there for a reason, or can they just be removed? Here's my nb.log file from when it failed:

Regardless, if anyone else can't play Majora's Mask with postLoader, do this:
* Install cios38rev17b to a slot you aren't already using. I recommend using ModMii for this - see Advanced Downloads.
* Compile postLoader, removing the above lines from addon/nandbooter/source/lz77.c.
* Make sure to set postLoader's game option for Majora's Mask to use the IOS slot in which you installed cios38rev17b.

Just posting in hopes that this gets fixed officially (I'm thinking there's probably an off by one problem causing a _Pos to be greater than the _Len or _Size variable once it gets to the final check) and helps others with the same problem.

Anyway, thanks for creating postLoader; it's a great SM replacement!

kuwanger · Apr 24, 2012

Looking at the code, I don't readily see any off-by one errors, and from what I know of LZ77/LZSS, it looks like it's properly implemented (I'm guessing on the 0x11 variant, but it just seems to be an extended version to allow greater runs). Certainly, I'd be rather weary of removing those checks because if nothing else they could lead to silent corruption of the stack/heap which could lead to all sorts of problems down the road.

If it really is simply an off-by-one error, it'd be safer to over malloc one byte and fix all the checks accordingly. But, it'd seem best to confirm that it's a harmless quirk by ripping out the relevant code and compiling it on a PC--to be able to debug it--then actually breaking at the point when there's the actual issue, to know exactly how and why it's breaking instead of just doing the quick hack solution. :/ But, then, maybe the MC developers did all the above. Unfortunately, I don't have MM to test/debug.

stfour why not add something similar to MC which manages/updates the NANDS SYSCONF? That way Mighty Channels at this point would become pretty much obsolete. Is it possible?

I think it would be useful, unless of course there is already a method to do this with the current PL3?

I suggested this probably 6 months or so ago but I don't think it was considered useful.

Yes, you are right, this is something that I left behind. But I doesn't considered it not usefull. Simply there are priorities and sometime my memory fails..

Thank you for pointing that... I will check what is causing this issue

postLoader 3.71.5

* nandbooter: removed an lz77 decompression check that may fail (thx Garfunkiel)

postLoader 3.71.4

* Added the capability to transfer SYSCONF and/or MII from real nand to current emunand ([HOME]->Nand options)

I'm not sure how much help this will be but here's the deal I have a 2TB hard drive in an external enclosure. I have one 40GB partition formatted fat32 with 32KB cluster size, the rest is one large NTFS partition. Using priibootergui, if I try to autoboot to PL through priiloader, it says it can't find postloader.dol. If I try to load PL via HBC it says it needs somewhere to save config files and gives me the option to create them on my SD card or boot to Wii menu. I've used the latest version of PL and first tried autobooting and then booting via HBC but without creating any config files on the SD card.

Attached is a copy of a ploader.log I did.

stfour · Apr 26, 2012

This is really strange... your first partition is not detected... Is it primary/active ?

DaFees · Apr 26, 2012

Unless Windows is lying to me and I've attached an image (disc 9 as labeled in the image is my drive in question) below to prove myself, my FAT32 partition IS marked primary/active.

stfour · Apr 26, 2012

I never tested Postloader with NTFS in advance of fat32... probably it is a my fault. Anyway I doesn't understand why you first partition isn't detected.

I need to setup a hdd like your, but starting from tomorrow I will be in holiday for some days... so you need to wait

stfour · Apr 26, 2012

~~meanwhile you can try this old version of postloader~~

~~please get > and run it with an sd inside the wii.~~

~~it will create on sd the following files~~

~~mbr.dat~~
~~part0.dat~~
~~part1.dat~~
~~etc..~~
~~etc..~~

~~If you send them to me it will be very usefull to understand what is happaning.~~

EDIT... probably this version will crash on 4K sector drive...

DaFees · Apr 26, 2012

Well as an update I tried the debug version you suggested, then unsuggested. That version had the same issues as the latest in that I couldn't autoboot to it and loading via HBC didn't work. It did generate the files in question though so I'll send those to you. Now for kicks I picked an old version of PL (3.57.1 to b exact) and it worked exactly as it should. I mean I still couldn't autoboot to it but loading via HBC worked as expected. So some where between that version and the latest version PL stopped working with my hard drive. Also the latest priibootergui then seems not to recognize my drive either.

Oh and I'm including the ploader.log of the working version.

Thank you. Just wait some days for the fix

Ok, that's good to know, if you need any additional info let me know.

zfa · Apr 27, 2012

Hi stfour,

v3.71.5 running under neek2o still has a 'set default loader' option available under the 'game options' menu. I'm guessing this is a mistake and should be removed - shouldn't all disc based games be running by whatever-it-is-that-neek-uses-to-run-games-with-di?? I think the option should be removed as it's confusing to have it there.

Cheers.

stfour · Apr 27, 2012

you are right... I will correct this when I'm back

DaFees · Apr 29, 2012

Hey stfour,

I wanted to let you know so as to may be save you some unnecessary work, but I figured out what my problem was all along. My FAT32 parition was primary and active BUT NOT first. With a little work I was able to switch the partition around and suddenly everything worked. So yes PL now works as expected and all is good for now until I have any questions getting PL to work together my neek2o setup,

stfour · Apr 29, 2012

Yes, I've read it from the neek2o thread... anyway I think that this wrong behaveur of pl should be fixed

DaFees · Apr 29, 2012

Ok Well I've read through the readmii and now I have a question about getting my neek2o setup to play with PL. I currently (using priibootergui) autoboot to PL and then if I don't enter interactive mode PL will autoboot to CFG. Now I know that using the neek2o channel or loading bootmii through HBC or renaming a folder on my SD card I can access my neek2o setup. Is there some way to view/use my neek2o setup from with PL? I have PL installed on my emunand and when I boot into my neek2o setup I can load the PL channel but then PL tells me it needs somewhere to save the cfg files and I don't want to let it do so without knowing what will happen because I don't want these new files for the emunand to interfer with the files PL uses when loaded from my real nand.

I basically want to mantain the autoboot settings I have now but also be able to access and use my neek2o setup while in PL. Oh and yes my emunand is in a folder called pl_us which is in a folder called nands which is on the root of my drive.

Also, how do you change themes in PL? I gave each theme its own folder with in the main theme folder but when I try to change to them in PL, it tells me it can't find them. Do I just pick which theme I want and copy that theme's files over top the default theme found on the root of the theme folder?

brownbailey · Apr 29, 2012

I'm hoping (once again) that I'm in the right forum.
I have a 4.3U softmodded Wii. I'm using neek2o to launch my emulated nand (uneek+di), and am trying to load all my games through Joyflow.

My question is this: I swear I was able to do all of this before without having to use an SD (besides the initial set up). Currently I'm unable to play any games through Joyflow without the SD, and I can't launch Postloader either, (neekbooter: postloader not found).

Do I have to make a second partition on my USB and use it somewhat as an emulated SD? or is it just a matter of copying some files over or injecting some wads?

A SD-free solution would be most appreciated. Anyone know how?

obcd · Apr 29, 2012

This sounds like the issue people were having when they used neek2o rev. 70 - 73.
I fixed it on rev. 74 (for uneek2o) and rev. 75 (for sneek2o) (Those revisions show a wrong rev. number.)

So, any chanche you changed your neek2o rev. and the problems started from that moment?
