Loadiine Wii U backup loader being ported to older firmwares
The popular Loadiine rom loader for the Wii U is being backported to older firmwares.
Initially released for Wii U firmware 5.3.2, Loadiine has now been ported by the GBATemp community to firmwares 4.1.0, 5.0.0, and 5.1.0 by different developers.
Developer ptileray has a 4.1.0/5.0.0 compatible port of Loadiine going on here. Another port, compatible with 5.0.0 and 5.1.0 is driven by NotKit and can be found here.
Depending on the port you use, Loadiine is now compatible with all these firmwares. In order to run Loadiine, you’ll need:
- Wii U FW 4.1.0/5.0.0/5.1.0/5.3.2
- SD(HC) Card
- (Optional) Super Smash Bros for Wii U (Disc or EShop version) – optional but may be needed for some games

You can find a list of compatible Loadiine roms on GBATemp.
Help, I’m on a different firmware, what do I do?
If you’re on a firmware below 5.3.2, one option is to update to firmware 5.3.2 via a Disc. Yoshi’s Woolly world, Mario Party 10, and Splatoon are known to ship with firmware 3.5.2.
If your Wii U is above firmware 5.3.2, there’s not much you can do at this point. Hopefully the upcoming Wii U 5.5.0 exploit from Hykem will unblock you soon.
Loadiine is NOT a ROM loader. It’s a backup loader, but disc based backups are NOT ROMs.
Aren’t they though? ROM stands for read-only memory and the cartridge based games you are referring to certainly are ripped from read-only hardware, but so is any pressed disc used as the physically media for any console today. Don’t forget it’s called CD-ROM, DVD-ROM, BD-ROM (although the consoles have always used a modified variant of those). Even digital downloads could be considered ROMs I believe as the files you download are never intended to be modified (the patches you may download are typically additional files) although they are typically stored on a writeable hard drive.
Ayyyyyyy! Got em!!!
***, just updated from 5.1.0 to 5.5.0….
Here’s hoping the 5.5.0 hack can use loadiine.
**** why the Wii U scene doesn’t have drama such as ps4 (especially the drama that it’s having right now) I’ve been reading the article about Cturt and flatz and now this and you can feel the difference between flaming ps4 scene and boring Wii U scene
Because we’re mature security researchers who enjoy each others company more then squeezing every last drop of e-fame we can ***.
hahahahahahaha maybe
Why not 5.2.. Smash bros early batch is came with 5.2…
