ROM Hack [Help] How to repack a System Title without exefs and exheader?

[Robotxm]

I'm trying to replace the Japanese font file with the Chinese one, but the title doesn't has exefs or exheader, so 3dstool cannot repack it.
Is there any way to repack this title without exefs and exheader? Or is there any other way to replace the font?

It can, but you're probably using cxi mode when what you want is a cfa!

3dstool -cvtf romfs new-romfs.bin --romfs-dir romfs
3dstool -cvtf cfa new-ncch.bin --header ncch.header --exh exheader.bin --romfs new-romfs.bin
makerom -f cia -o customfont.cia -content new-ncch.bin:0:0x00

The colored variables come from the original cfa extracted with ctrtool, the file with numbers that you extracted into romfs.bin!

Good luck!

Thx a lot. I tried but MakeRom said "Failed to build CIA".
Because the title I modified doesn't has exheader so I deleted the argument "--exh".

Yeah, I wasn't too sure if a cfa used an exheader...

Try manually specifying a version by also adding to makerom: -dver (the version number you would use in 3dnus or higher)

I tried but failed again.
makerom said that Conten0 is not NCCH.

Hmmm that means 3dstool is creating files wrong... are you sure the ncch.header is coming from the correct original CFA?

Thank you very much. I'm a boarder so if you don't mind, I will send the bcfnt to you on the next weekend.
BTW, the bcfnt was extracted from 0004009B00014002 v0(JPN/EUR/USA System Font) and 0004009B00014102 v1024(CHN System Font).

I have made it by using FontTool.py.
Anyway, thx again.
