Hi,
my problem is still unsolved. I'm trying to patch my EU games with hans, firmware is 11.0, old 3DS. I summarise again what I did:
1. Downloaded homebrew starter pack, extracted the data and copied them to an unused SD card.
2. Downloaded Braindump. Extracted the data and copied the files into “3ds” folder from starter pack inside the SD card.
3. Inserted the SD card and my FE fates Birthright into my 3DS. Used browserhax to reach homebrew.
4. Started hans, chose Romfs -> SD “yes” and noted Romfs path which was sd:/hans/00179500.romfs
5. Then I launched Braindump and selected my game. It started dumping.
6. When finished I put the SD card into my PC. I copied the new folder “0004000000179500” with romfs and exefs inside to my PC and extracted the data from romfs with RomFSExtractor. That created the folder “romfs_”
7. Downloaded the undub patch from OP and extracted the data. I copied the content of the “rom” folder from patch to the romfs_ folder, overwriting the files with the same names which were already there. Because I have the EU version, I copied the file from “@E” folder to @F, @G, @I, @S and @U.
8. I started RomFSBuilder and chose the the patched romfs_ folder, then clicked Go. When asked I named the new file “00179500.romfs” (see step 4)
9. I copied the the newly created file into the hans folder on SD card and moved the hans folder to the root of SD card, then inserted the SD card into 3DS, the game still inside.
10. Went into homebrew and started HANS. Again chose Romfs -> SD “yes”. It didn’t say the path is invalid. Then I clicked OK to start the game. First there appear some lines on the bottom screen, then some lines on the upper screen, then a vertical white beam on the left side of upper screen, then only black screen and I have to turn off the power of the 3DS.
I tried the same thing a few times from beginning, even with Conquest and the 3DS of my brother. Also tried without the patch, just rebuilt the extracted romfs file again. But I got always the same results :(
I’m thankful for any help.
