I want to emulate Up for the DS for my show.I got the game file from here https://www.emuparadise.me/Nintendo_...50197-download. Since I use a mac the recommended emulator to use was DeSmuME. I download the Up file and it instantly goes to the unarchiver by clicking it. I try to connect it to DeSmuME but it does not work. Can someone explain what I need to get or what I am doing wrong?
