8x8 and 16x16 tile font

May I ask one question: in a Rom that uses 8x8 tile font, how do I change it to 16x16 for more space (I want to add morething to the letters).

I mean the Rom is Snes and I don't know ASM 65816.

I translated some Roms, all of them are 16x16. Now I encounter a Rom uses 8x8 and so it's not enough space for the letters for may language alphabet. My language uses non-linear alphabet, which has many symbols above each character.

Thank you very much.

Chances are that if a game uses an 8x8 font, then it's coded in such a way to have all characters available at all times, and just use tile numbers to draw text.

Such a game will require significant rewrites to the text engine to
* Draw more than one tile per character
* Render a big tile inside VRAM
* Not run out of VRAM because all characters need 4 tiles worth of space in VRAM, that may exhaust a game that only has English or Kana characters in VRAM
* Expire old tiles as needed
And there will probably be many copies of the text drawing routine thrown randomly about the rom.
Good luck learning ASM.
