Portrait removal patch request for FFVI advance

There is no such patch sadly. What you could do though is replace every portrait GFX in the ROM with 00 (transparency). Here are the offset for all GBA version. You would get the same result as your picture as the text still start after the portrait space in the dialogue box.

Code:

5FE83E     60301D     GFX     Portraits (800 bytes * 23 entries)
