Hello. I edited my save file for MPT to have 16 Green (Friend) credits, and I need to know how the game calculates the checksum. My PC isn't fast enough for Dolphin, I don't have a USB Gecko, and the latest DebugFast Build of Dolphin, despite following all directions, doesn't completely compile. Can someone with the right tools follow GP's process here for me, then post the fixed save? My save is on my Skydrive here. Just edit the offset 0x16D to 0x10, then follow the steps in GP's post. Thanks to anyone who can help me.
