For the HBC...I think I mentioned it before (here or elsewhere), but the 1.0.8 channel won't work on sneek/uneek. And I'm one of those who found out about this the hard way.
The way to get around to this is as follows:
1. install 1.0.7 on your real nand.
2. make a dump of your real nand (bootmii).
3. extract the wad of the HBC on that dump (I think showmiiwads is the program for this).
4. install this same wad on your uneek wad.
It's a bit complicated as team twiizers doesn't like others redistributing their channel, but the HBC is a good thing to have on your sneeked nand for more than just priiloader.
There is an alternative way to install priiloader. But you'll need a dumped nand with the same system version as your uneek nand AND have priiloader installed on that nand. The way to go about it is sorta described
here.
Basically: go check out the folder "\title\ 00000001\ 0000002\ content\" on that dumped nand with priiloader installed. There should be exactly 1 file that starts with a one (100000xx.app...where xx is a number). That file is the original system menu, but it got renamed when you installed priiloader. In addition, there is a 000000xx.app file (with xx being the same number). This is priiloader when it's installed. Mark this file for copying.
Then go to your uneek'ed nand. Make your way to \title\ 00000001\ 0000002\ content\. There should also be that 000000xx.app (which is the system menu of your uneek'ed nand). Rename this to 100000xx.app, then paste your earlier copied 000000xx.app in its place.
...and can someone please confirm deny all this? I just followed this logic because of a problem with priiloader, and made it uninstall and reinstall manually (even though it turned out to do the same thing in HBC).
@scooby: at first, I was going to report failure with 0.4 as well. It too just black screened (or white screened, when on that setting) on some settings. But when investigating, I found out that if you select your choice quickly after priiloader runs, the desired menu actually pops up. No idea why it does that, but considering priiloader isn't exactly designed for sneek, I'm certainly not one to complain.
(I don't USE priiloader often...it's mostly automatic anyway).
