Step 2: Backup Your Files
Before you inject anything, copy your game.chd or game.gdi file to a separate folder. Mods can sometimes corrupt the ROM.
Step 3: Extract the Mod Package
Most DcGameMods come in a folder structure: /data, /textures, or /mods.
Step 4: Configure the Emulator
Step 5: Test the CRC
