I discovered that the Masterpiece section in “Dairantou Smash Brothers X” has all of the Virtual Console-ready files for Mother2. I also discovered that "Dairantou Smash Brothers for Wii U" has similar files in its Masterpiece section. The naming convention of the files “JBMJ” matched the way other Super Famicom Virtual Console games have their product code. This version of Mother2 was only ever used in the Masterpiece sections.

After seeing that there’s no way to save using some hacked version of “Dairantou Smash Brothers X”, I figured I’d try doing something like this video:



From what I can tell, that person used the files that I plan on using. The emanual file matches the one I extracted.

I've come across a point where repacking the wad isn't working. If someone could let me know if I'm missing something super obvious, that would be amazing.

What I’ll need to change/modify in an existing Wii SFC VC Wad:

1) Game Files:

Using Dolphin, extract the following from:
"Dairantou Smash Brothers X/P-HBJJ/files/content5/:"
*emanual.arc
*home_nosave.csv
*home.csv
*JBMJ.pcm
*JBMJ.rom
*JBMJ.var
*Opera.arc


2) Banner:
1) Extract "Super Donkey Kong 2 - Dixie & Diddy (Japan) (SNES) (Virtual Console).wad" file as a base
2) Go into extracted WAD files directory
3) Unpack 00000005.app file using U8Tool
4) Copy game files listed in the above section and replace the same named files in the 00000005 directory.
5) Delete the JBDJ.pcm, JBDJ.rom & JBDJ.var files
6) Decode banner.tpl file using wimgt
7) Edit the banner.tpl.png images

8) Encode the banner.tpl.png images into banner.tpl using using wimgt
9) Pack the 00000005 folder back into 00000005.app file using U8Tool


3) VCPic:
1) Unpack 00000000.app file using U8Tool
2) Unpack 00000000/meta/banner.bin using U8Tool
3) Decode the banner/arc/timg/VCPic.tpl file using wimgt
4) Edit the VCPic.tpl.png image

5) Encode the VCPic.tpl.png image back into VCPic.tpl using wimgt
6) Pack the 00000000/meta/banner folder back into 00000000/meta/banner.bin using U8Tool


4) IconVCPic:
1) Unpack 00000000/meta/icon.bin file using U8Tool
2) Decode the 00000000/meta/icon/arc/timg/IconVCPic.tpl file using wimgt
3) Edit the IconVCPic.tpl.png image

Txly76r.png

4) Encode the IconVCPic.tpl.png image back into IconVCPic.tpl using wimgt
6) Pack the 00000000/meta/icon folder back into 00000000/meta/icon.bin using U8Tool
7) Pack the 00000000 folder back into 00000000.app file using U8Tool


5) Misc Files:
Copy the following files from "Dairantou Smash Brothers X/P-HBJJ:"
*cert.bin
*ticket.bin
*tmd.bin

Rename them:
*000100014a42444a.cert
*000100014a42444a.tik
*000100014a42444a.tmd

Place them in the extracted WAD directory


6) Repacked WADS with the following:
*WADpack_WADunpack (with gbalzss)
*wwPacker: https://gbatemp.net/download/wwpacker.36649/
*https://github.com/asdfjkluiop/wadpacker
Both resulting WAD was 427kb

*Devilken's VC Injector:
https://gbatemp.net/download/devilken-vc-injector.35061/
Didn't work

I looked at the other tools in the “saulfabreg AIO Wii VC iNJECT Tools v4.8.0” package and none seemed to help.

Is what I’m trying to attempt actually possible? If so, is there a way to accomplish this that I haven’t thought of? Any suggestions would be amazing.

I forgot all about Masterpieces, wow. I have no expertise in this, so sorry I can't help, but I'm curious nonetheless. Are you attempting this just for the sake of doing it?

Yeah, my goal is to mimic what an official Mother2 Wii VC release would've been.

@celebi23 Any progress?

If you couldn't do that, could you please send me a PM (private message) me with the files you got of "official" Mother 2 from Japanese "Nintendo All-Star! Dairantou Smash Brothers X" for see if i can try to build an "official" WAD of that? I can't get a Japanese copy of that game for try to extract by myself.

@SaulFabre, I mostly got it working. I was able to use the actual JBMJ.rom JBMJ.pcm and JBMJ.var files in the step where you open up the 00000005.app file. So, it was nice to be able to use the actual files from Dairantou Smash Brothers X. There are a few issues that I go over below (there's a decent amount of screenshots):

So, I installed it to the NAND in Dolphin to get the full experience. I was able to download Wii System Menu 4.3J.

The game has the correct image and title
0000000100000002_2022-02-19_22-07-34.png


It has the correct Title, Release year and number of players
0000000100000002_2022-02-19_22-07-43.png


When I try launching it from this screen, I get sent back to the Wii menu
0000000100000002_2022-02-19_22-07-55.png


The channel information is correct
0000000100000002_2022-02-19_22-27-10.png

0000000100000002_2022-02-19_22-27-15.png


If I launch the WAD directly from Dolphin
Screen Shot 2022-02-19 at 10.33.47 PM.png


The game runs fine
JBMJ01_2022-02-19_22-10-09.png


Even the minimal emanual taken from Dairantou Smash Brothers X works
JBMJ01_2022-02-19_22-09-00.png


JBMJ01_2022-02-19_22-09-06.png


I can start and save the game
JBMJ01_2022-02-19_22-11-00.png


JBMJ01_2022-02-19_22-25-50.png


The Wii system remembers where the game left off
JBMJ01_2022-02-19_22-37-51.png


And the game actually saved and I can resume my save file if I reset the game
JBMJ01_2022-02-19_22-28-55.png


JBMJ01_2022-02-19_22-29-04.png



The save name still reflects "スーパードンキーコング2 ディクシー&ディディー" even though I changed all instances of it to "MOTHER2 ギーグの逆襲".

I followed your guide super closley and even redid the process a few times to see if I missed anything.

Here's how the wad is showing in Dolphin:

I also verified the wad's integrity in Dolphin. I have no idea if this information is helpful at all:

I hope that wasn't an overload of info :D Any thoughts as to what is causing those small issues I mentioned? Thanks!

Then maybe you're doing the creation of the WAD wrong.
I recently made some FC/SFC Japanese Wii VC WADs with no trouble.
You still need to PM me with the files you got for see what can i do with these and try to make an "official" VC WAD of that Mother 2 game but without the issues you mentioned.

Sending the PM now. I wanted to see if I could get things working first. Thanks!
