Master Boy .sav files to computer help!!!!!!!

Ok i am pretty new at emulation and i have a quick question. Over the past few days i have been trying to play pokemon games on my computer with cheats. I am using the program called BGB to emulate GBC and BG roms. Well I decided to try and put the .sav file into the Master Boy emulator on my PSP and it didn't work. I was able to take the .sav file on my PSP from a XXXXXXXXXX.sav.gz save file in Master Boy and put it in the GBG emulator. I am not able to put a .sav file created in BGB into the SAVE file found in Master Boy. If you know how to convert it to work in Master Boy please help.
