hi, my english not good, so please Be patient, thanks.
I localize lego batman 1, i translated txt file to chinese. find the font file, and i Understand the file structure.
but if i change the font size, This game won't start, if i just overwrite this font file hex and don't change file size, this game work and displays chinese.
so i think The problem lies in game exe file.It limits the font file size.(if i delete some hex change font file size, the game not work)
But I don't know anything about EXE file. if you Know how to solve it,please tell me.
thanks.

this is game exe file and font file

There're 2 offset at 0x0 (size file - 68) and 0xC44 (size dds - 68).
I'm not sure if you've edited this.

0x00 - size without footer (-68 bytes)
0x08 - size of table
0x1C (or 0x20) - number of entries?
0x48 - size of first table?
0xC44 - size of dds without footer (-68 bytes)

OMG!I always thought it was fileHead And ignore it.
but i Checked other files. this is real file size flag!
I don't know if the change will work, but this information really escaped my attention!
thank you!!!(I don't know how to say thank you in English,so thankkkkkkkkkk you!!!!!)

thank you!This problem should be right in the 0x00.I thought this was the file header and ignored it.
0x08 - Except for the size after DDS
0x1C - Number of characters included DDS
0x20 - characters mapping
0x48 - size of Number of characters included DDS

} fnt;

this is i edit 010editor template for this game font file.
i insert one glyph.
insert 0x8F4 12bytes.
insert 0xBE4 4bytes.
change 0x00(file size - 68 bytes) 16 bytes.
change 0x08 16 bytes.
change 0x18 16 bytes.
change 0x48 12 bytes.
DDS just export write and import it(file size not change).
can't open game.

if i just write and not insert(font file size not change), game work and show glyph change.
Could it be related to the footer?
thanks!

i found lego star wars font file.
I put this file directly into batman folder, the game is open!
I compared the two files and tried to modify without changing the size,I found that the most likely problem is the footer.

I found that just keeping the 32BYTES footer game can run normally.
batman font file footer is 0x6270

this footer 0x00 > 7
0x04,0x08 => Binary => (1 <-> 0) = fileSize(fileHeader) - 1bytes
0x0C,0x10,0x14,0x18,0x1C => Binary => (1 <-> 0) = fileSize(fileHeader) - 45bytes
The rest can be deleted.
Thanks to the people who helped me.it's work!
