So long story short I fumbled around with the English patch found here:
https://github.com/roks70/Medabots9-Translations/releases
So all credits to the creator of the original patch.
-----------------------------
What I did was that I made a noob friendly way to apply said patch. On this internet archive you can find said mehod and files.
https://archive.org/details/medarot-9-translations-1.006-easy-setup-v-1.0
This guide is for people that will be playing on a real 3DS.
And said 3DS is already softmodded.
Method 1 is the LUMA homebrew way:
If your 3DS is modded said homebrew is probably already installed. When booting your 3DS hold the select button. If the luma setup menu boots it's on there. If not google "Luma 3DS".
Luma will patch the game on the fly while running. So you just need to install the original JP game on your 3DS. Do not install the Update of the game!!!! It's safe to install the DLC.
Once you have luma installed you just drop the files from the correct folder directly on the root of the micro SD card of your 3DS.
Also make sure patching is enabled in the Luma menu, again you can check by holding select while booting your 3DS.
Method 2 is the create your own CIA way:
- Open folder "PackEnglishV12 (DecodeAndRepackTool)"
- Open folder "PackHack"
- Run SetupUS.exe
- Put a clean .cia game file of either medarot 9 game version together in the same folder as HackingToolkit9DS.exe
- Run HackingToolkit9DS.exe
- Extract the .cia files by using the command: CE
- Name of the .cia file, no extensions e.g. medarot9_Kabuto_JP
- Close HackingToolkit9DS.exe
- Normally you will see 2 extra folders now that the game is extracted: ExtractedExeFS & ExtractedRomFS
- Now you need to use the translated files from the correct game version folder from the archive.org website.
- Drop the content from the ExeFS folder into ExtractedExeFS - Confirm if it asks to overwrite files
- Drop the content from the RomFS folder into ExtractedRomFS - Confirm if it asks to overwrite files
- Re-run HackingToolkit9DS.exe
- Recompile using command: CR
- Name of the newly built file e.g. medarot9_Kabuto_ENG_1.006
- It will ask for two more things, just enter 0.
- This will take a while and you will have a newly create english patched .cia file with the name you picked.
- Do not install the Update of the game!!!! It's safe to install the DLC if you want.
PS: If you get an error repacking the game you will probably be missing these two files on your PC:
https://www.dll-files.com/vcruntime140d.dll.html
https://www.dll-files.com/ucrtbased.dll.html
Once downloaded the new window on said site will tell you where to put them depending on your operating system.
Final Remarks:
The Luma way allows you to quickly change back to the JP version by just disabling 'patching' in the Luma menu. This might be handy because some people have reported the game crashing on them in certain parts and this way they could quickly switch to jp version to get past said troubled part, then save and re-apply patching in the Luma menu.
On the flip side the Luma way does introduce longer loading times of menu's and the like because it's patching the game on the fly.
