okay with all these informationguide for repacking and patchin that was used:
The 'Japanese version 1.2 update' was downloaded from the eShop and decrypted using my 3DS.
Then, using Asia81's 'HackingToolkit3DS' Tools:
1. The 'Decrypted Japanese 3DS Rom' was unpacked.
2. The 'v1.2 Update Data' file was unpacked.
3. The Update ExeFS/RomFS contents was copied over the original 3DS Rom extracted files.
4. The 'DecryptedExHeader.bin' was modified (Offset 0x1CC from 0E to 00) and replaced the one in the original 3DS Rom.
5. The 'English Translation Patch files' were extracted and copied over to the 'RomFS' replacing the files in the original 3DS Rom.
6. The 3DS Rom was rebuilt and then trimmed.
is it possible to do withou 3DS ?
