Could someone please tell me step-by-step how I'm supposed to do this? I have the latest CopyNES DOS software, PowerPak boot ROM, etc. I have also performed the flash cart mod as shown on kevtris's site. I tried all three RAM cart options (NRAM, CNRAM, UfROM), and now I'm left with a dead PowerPak. I know the CopyNES works fine because I've used it to back up several carts. Please tell me what I'm doing wrong here...
