Note for the following post: EN = Emu Nand
So what I have to do is create a copy of my "NAND" folder and put it on the root of my HDD? Then I install rev 19 on it and set those games to work with that instead? If so where to get rev 19?
If your emunand is on a folder ( for example /nand), yes you need to make one that is ON THE ROOT of your HDD (meaning, that you must have the folders shared1, shared 2, sys, ticket, title, tmp etc. on the root of your HDD). This is cause non d2x IOS's require that the EN is only there and not in a folder.
However, you can simply
move the current EN you have, on the root. You might ask why didn't i simply do that to my own, well i had manually edited each game's setttings to point for nandsaves to the folder usb1:/nand so i was reaaally bored to do this again for 600+ games.
Most importantly though: I hadn't yet installed rev17 on IOS 240 and rev 19 [base 38] on IOS 249 on my Wii, back when i made the original emunand on the /nand folder, so i had to make a new one for the problematic games on the root, after installing those 2 IOS es on my real nand.
Now for the games, as i said, ALL minus 8 games/channels work with specific IOS's.
I will attach my syscheck to this post, to provide a reference for what you need. Just keep in mind that for the
problematic N64 games like Zelda MM, Ogre Battle, Pokemon Puzzle, Cruisn USA etc, i use IOS 249 and this is also used for for Wiiware like Bonsai Barber, Motoheroz or the large neo geo VC like Last Blade 1& 2.
Finally, and ONLY for MDK2, Whiterock Castle & Beaver Defence, use IOS 240.
The only games/channels that require real nand are:
2 Fast for Gnomz
Let's Create Pottery
Hot Rod Show
Liight
Castlevania Adventure Rebirth
Rubik's Rush
Opera Browser
Youtube Channel (official)
There are also some specific inject wads like Hexen 64 that need RN, but those are another story.
Use ModMii to find the IOSes, i use
IOS240-v17, IOS249-v19[base 38] and all others from 241-251 are v8 (v10 is newer, might work better, i can't say as i haven't used it myself).
So
TL; DR:
1. install IOS240-v17, IOS249-v19 on your Wii (if you cannot find those, PM me).
2. Now make a
new Nand backup either via Boot Mii or w/e.
3. Extract it with ShowMiiWads and put it (ie the shared1, shared2, sys, ticket. title, tmp etc. folders) on the ROOT of your HDD.
4. Use showMiiwads to add the wads of the problematic games you have. You can also remove unecessary channels like weather, etc from the nand back-up, to save space.
5. Install the problematic games on the old emunand (the one you had on a folder) AS WELL. This is cause GX will only ''see'' 1 emunand at a time, for gamelist. So in order to have the problematic games show up on GX, you must install them on both ENs
6. Use the ''settings'' for each problematic game and point it to usb1:/ for the emunand location (instead of say usb1:/nand/ that is used for all other games). Meaning, make the game to use the new EN instead of the old one.
7. You might also need to make any problematic game to use IOS 240 or 249 (again, use the ''settings'' for each problematic game). I already gave some examples in my post about some known problematic titles and what they work best with.
Have fun!
