Here we go again... A piracy discussion... SO FREAKING WHAT????!!! Who cares if it can enable it or not?
Just be happy we have homebrew. Otherwise we can better have nothing and just go on with our lives...
I'm against online cheating though.
Think about it, don't you want:
- Emulators.
- 3DS Controller for Wii U.
- Make the Wii U Pro controller act like a Classic Controller in vWii so that it actually can be used.
- NAND backup the same way as it did on the Wii (No hardmod stuff).
- Stream 3DS screens to Wii U TV if possible. Also good for capturing 3DS footage without a 3DS capture card.
- PAL/PAL60/NTSC video mode switching. That will work incase your Wii U doesn't work well on your TV, and it has more capture card support.
- Regionfree.
- FTP server for Wii U so you can place files from your PC to SD/USB. Very useful if you don't have a card reader.
- VC injects.
- More maybe?
So yeah...
Most of the stuff on this list either has nothing to do with wiiu side or even needs iosu to be acoomplished...
-Emulators could be writen as off now with kernel but no one bothered, the only thing they would benefict from iosu would be usb acess, on everything else you gain nothing on emulators in iosu vs kernel people just dont have much interest.
-3ds controller has nothing to do with iosu at all, iosu wouldnt mean anything to this feature, all you have to do is hack the game controller code same way FIX94 made gc to vpad using kernel but no one bothered making this for 3ds yet becuase well 3ds is by far the worst controller for the wiiu available lol.
-wiiupro as a classic controller on vwii has nothing to do with wiiu mode, let alone iosu, you could make this happen day 1 the vwii had homebrew same way wiiu pro works on nintendont on both wii and vwii, but people never made any hack for them to work on regular wii games same for hid controllers like the wiiu gc adapter, all they work on nintendont they can work on wii games but people would need to actualy hack that.
-nand backup does need iosu
-Stream 3ds is not possible 3ds is not powerful enough to even stream video, if people cant even steam it to the pc hell no they would for the wiiu, thats why there is capture cards becuase 3ds cant stream its video.
-video modes if your tv cant do the hdmi connection well why to even bother having a wiiu? lol next thing your gonna tell me people play wiiu games in crt tv and need a pal50 hack...
-regionfreee does need iosu.
-wiiu server does not need iosu yet again, this is already possible, even loadiine and cafiine had a way acess isos from a server but the thing is wiiu internet is crap so unless you want huge waiting times your better off with sd/usb, nintendo consoles internet speeds always sucked.
-vc injects we have been doing them since 5.3.2 kernel acess iosu wouldnt help this at all. since we can already do it...
So basicaly of everything you said only 2 things benefict from iosu, region free and nand backup everything else either has nothing to do with wiiu itself or even beneficts from iosu acess.
