I have used xploder for years. its still good. but I have never owed game genie, they do offer more from what I seen. only downside to xploder is there is a lot of bad saves with neg reps and still haven't been removed. at least with game genie all saves are checked and updated regularly. I am xploder user since playstation with the cartridge plug in on the rear. was the real modding days with hex codes

if you can spare the coin and a fan of ngu support their product like me. I believe there might be a trial version too
