Manual conversion with hex editor Manual conversion with hex editor Make a note of the save(s) you want to use on the PC version as above i.e. save 0, 1, 2, and/or 3 Insert a USB flashdrive into your Xbox360 Use your Xbox360 Settings menu to copy your Arkham Asylum savegames to the drive Complete transfer of files to your PC - there will be a "Content" folder on your USB drive, and your saves will be in it, search for the files save0.sgd , save1.sgd etc depending on which you want to convert Open the save file you want to transfer in your hex editor Go to offset 0xD000 , or search for the first occurence of 0x9E2A83 - I have only seen this near position 0xD000 in my saves, but it may vary. Delete everything before position 0xD000 You should end up with a file starting with 0x00 0x00 0x01 Now scroll down the file until you hit a big block of 0x00s. How far you have to scroll depends on how much is in your savegame. It will be a big block, you can tell it's the right block because before it you'll see lots of game related words like Harpoon Gun, Objective, but afterwards just gibberish Look at the top of the of block of 00s and find the last 0x11 byte, this is the "end" of the real data. You may have 9 or so bytes of 0x00 before it Delete everything AFTER the 0x11 so that the 0x11 is now the last byte in the file Now make a note of the offset of the 0x11 - this is Value A . Go back to the start of the file. Insert 4 bytes of 00 00 00 00 at the start. Your file will now begin 00 00 00 00 00 00 01 ... You now will change the 3rd byte. If value A is less than 0x10000 - it will be 01 i.e. your file will start 00 00 01 00 . If value A is more than 0x10000 - it will be 02 i.e. your file starts 00 00 02 00 . And presumably onwards to bigger depending on save length e.g. if A > 0x20000 use 03 and so on... In actual fact, I've tested this up to 09 - it's just important that it's more than 1 (or rather, more than the number of 0x10000 blocks length that your savegame is) - it seems to be just an initialisation size for some sort of uncompression buffer so needs to be at least big enough. Save your changes. Copy your edited save into the correct folder as documented above, or in MrJAG's video on Youtube - TUTORIAL Batman Arkham How To Install SaveGames
