Yo what emulator you use man? Probably problem regarding your emulator bro. I use myboy and what I did to make it work is to put the rom and patch in the same folder and rename the ups file the same as the rom "Fire Emblem (USA, Australia)". I haven't tried naming it the other way around but it will still work probably. If that doesn't work patch the rom first on pc and copy it to your phone and use myboy instead
