for best results make sure that the game you use as a donor matches exactly the info that your able to gather from the file you want to put on it. bobby's world for instance under

HiRom at the top it will either be yes or no if its no its a LoRom if is Yes then it is HiRom

Rom speed pretty self explanatory make sure it matches

for games that don't have saves or high scores you don't need a battery so it would say ROM only under Rom type now if you have a donor cart that has SRAM but all the other info matches then it will still work fine

another reason why I'm posting this here is so that I can link to it when needed for an E-zine Article
