Hello, I'm the guy that's translating Katekyo Hitman Reborn.
The font file has two parts that both contain fonts but one is bigger: font_1x1.chr and font_2x2.chr.
I know that .chr format is a graphic. When I open it on Crystal Tile 2 and extract it then make edits to it
to try make it smaller because the English letters are too big. When I play the ROM afterwards,
when the letter/s i changed show up the ROM crashes immediately.
Can someone help?

Sorry  \ I forgot to check. Thankyou I can now change the font but it is monospaced and when making it thinner it will leave huge spaces between the letters. I have very little knowledge of ASM hacking so I can't add my own font  Any ideas?
