Respuesta: [Esmeralda] MTs Reusables para Esmeralda Español
It isn't as simple as you have shown. By changing one function in the ROM you can't achieve that. You need to make a function either in ASM or C and there a routine for FR and porting for EM would be easy as well.
The OP is updated with images and a new Download link :)
EDIT: Some of the OWs need some revamping and I won't be getting much time to work on them. I need someone to help me. If you are interested please DM me.
