24 bit monster HP patch

The third byte of the HP is located from 0FD150 to 0FD2CF (CF/CF50 to CF/D0CF). The order of the monsters is the same than the one in FF3usME. As an example, if you want to edit samurai's HP (monster #004) you edit the byte at 0FD154.

Now let's say you want samurai to have 8 000 000 HP. That is 7A1200h. Use your windows calculator if you don't know the hexadecimal system. The byte at CF/D154 will be 7A. For the rest, you can edit the 1200h (4608) with FF3usMe or change manually it in the monsters data (0F0200 to 0F31FF), but I won't cover this.
Your monster will have 4608 HP on the first 2 bytes and 7 995 392 HP on the third one.

Judging on where the original monster data is stored according to your post, I assume this is meant for the SNES version of FF6. I'm currently using the GBA ROM which has monster data starting at 73798A instead of 0F0200.

Even after applying the patch (which apparently went through successfully) I cannot find where the 3rd byte is for HP. Can I assume this is not compatible with the GBA version or am I completely off here? I am quite new to this
