I happened to find this at an electronics thrift store and they gave it to me for $5. I don't need any more GBA carts by any means, especially a strictly NOR based cart, but I wasn't going to pass on it for $5. Problem is, I don't have the slot one cart that comes along. I do have an M3 Simply though as well as Gateway blue cart. Are there any options to flash this sucker with a non EZF slot 1 cart or do I need the official EZ cart? Kind of confused why it was sold as a standalone if you can't use other slot one carts with it.
