- v4.2 broke something (region free I think?) from wiikey, and affected games launched from the disc channel. there's no problem updating to 4.3 if you use USBLoaders to launch the game.
Wiikey released few 1.9x version, I don't remember if last one is b or s (it was always done to fix a specific game, like s version to fix dual layer for Smash bros, etc.)
I can do some search if needed, but again as long as you don't play burned disc from disc channel then wiikey version has no effect and will never conflict. (except if you try to dump a dual layer game without the S version)
- v8 is the same as v10 r52
v9 is the same as v10 r53
d2x got a version increase due to vWii release, v9 was beta and unstable so instead of releasing it the developer decided to revert the changes and make v8 compatible with vWii instead. But to prevent confusion with "v8 vWii being newer than v9 wii" he decided to make them both v10 and v10 alternative, for both Wii and vWii.
don't update to v10-alt (r53) it's buggy. keep either v8 or update to v10 r52 (no reason).
- Hermes' cIOS are rarely used now, and probably useless. they don't even work on vWii, and all games are working (well, almost, there are still incompatible/anti piracy checked games).
the 249-56 and 250-57 is the common setup and all (relative) games will work. though, some games will require base57 (call of duty, just dance 2017)
That's why I recommend only base57 when I tell users to install only ONE cIOS to make a minimalist installation guide. one single cIOS on the console plays 99% of games. (there are still games like Tintin or Driver not working)
- I never used Priiloader, but installed it recently on my brother's console to bypass the menu and HBC (because my nephew deleted homebrew by mistake. I locked everything and only USBGX is now possible to use on the console).
If you have bootmii boot2, you don't "need" priiloader, but it could be useful if you want menu hacks (like auto press A at boot, prevent disc update, etc.) but personally I don't need it as I bypass the system menu completely with boot2->hbc
do like you want after updated to 4.3
If you have a wiikey, chances are you have bootmii possible into boot2, as long as you have a NAND backup (or your keys) you can rescue your console in case of brick.
If you don't have boot2, then yes you should install priiloader as it's the best way to bypass and fix semi-brick state.
as for Updating it if you already have v0.7, I don't know what is really improved. I don't think you need it. the feature which could have been useful is not working as intended so it's useless.
Don't risk updating.
Except that if you update the system menu, and you already have priiloader + hacks, the adresses will not match anymore! you might have to follow modmii if you want to update your console and get all latest IOS and system version.
- CFG was good for wii, but I don't know if it's still updated.
Now both USBLoaderGX and Wiiflow are up to date with latest possibilities (nintendont, vWii)
I don't know the latest wiiflow, because there's a "mod thread" which is probably newer than the official one.
the latest usbgx is in my signature, official pinned thread or on sourceforge's official repository.
- MultiModManager was never the best one, never liked it cause it's closed source, breaking GPL, etc.
it's old and I don't know if it has been updated/maintained to support AHBAccess instead of cIOS236.
Best manager is probably this one, for both Wii and vWii :
https://github.com/FIX94/Some-YAWMM-Mod/releases
it works with the official IOS58, no need to have any cIOS to manage wads.
- DOPMii ... I always mix that name with another tool. Is that the "automated softmod tool" like Pimpmywii, or the system IOS manager?
if it's the IOS manager, it was nice back in the time, as you could check and edit your cIOS yourself.
I don't think it's needed now, it works only on Wii (not vWii) and it could be dangerous.
If it's the "pimpmywii" clone, don't use it! don't trust tools editing your console in batch for you.
or you think about ModMii instead of DOPMii?
- Syscheck is just listing your IOS slots, you can use old version without issue, but latest/best/maintained version is probably in my signature too.
