In order to patch, you will need a clean Pokemon Emerald rom. It's recommended that you look up and download the 1986 Trashman version. If you don't want the day/night system, use the \"No RTC\" patch instead.
Follow the patching instructions and download the game files listed, then load the game into an emulator in order to play. Do not try to load the .RAR file from the Discord server into your emulator, the stuff that you need is in that file, which can be accessed by downloading WinRAR or 7Zip. 59ce067264
