I don't know where you are trying to download the files, but ALL the official releases of d2x are here :
https://github.com/davebaol/d2x-cios/releases
And you don't need registration on another forum to access files.
if you tried "last mirror" from this thread :
https://gbatemp.net/threads/ciosx-rev21d2x-yet-another-hot-fix.277659/
then it's written in BIG LETTERS AT THE TOP : OUTDATED !
v6 final is NOT the latest anymore, and lot of games are not working. you need at least v8 !
latest final is v8 (for Wii).
but there are new beta releases since v8:
v9 (never released)
v10 r52 (actually v8) officially re-release for Wii and released for vWii
v10Alt r53 (actually v9) beta officially released for Wii and released for vWii. ATTENTION, NEWER IS NOT BETTER! use r52 instead ! r53 is BETA with bugs!
v10 d2xL mod by leseratte for wiimini, beta not officially released yet.
If you need the installer, it's bundled only with v6.
you need to prepare and mix both the installer with the d2x version you want to install.
if you want, I created full packs from v6 up to v10r53 in a single app, for both Wii and vWii.
don't mix them.
Merged pack Wii d2x installer 3.1 (v6, v7, v8, v10, v10alt) (requires Nintendo's server access)
Merged pack vWii d2x installer 2.2 mod (v10, v10alt) (doesn't need network access)
They both are missing the v10r52 FAT32 mod for Ustealth compatibility with emuNAND.
and, if you don't know what to install, please read this guide:
(just replace the mini version in that guide with the version you want, v8 for wii, r10r52 for vWii. DO NOT INSTALL d2xl on Wii yet even if compatible, it's beta !!!)
