Oh ok. I think I got the first part!

Let me edit this and reverse it and I will share how to do it and help those that need it. Give me a minute, figuring it all out.

--------------------- MERGED ---------------------------

Step 1: Open your Hex editor (Mine is HxD) and open your Switch file ff8slot00
View attachment 178470
Step 2: Look at the first 4 bytes: this tells you how long your save file is, no need to convert: Mine is 26 09 00 00 (read right to left) 00 00 09 26 Mine is 926
(If yours is something like: 34 08 00 00, it will be, 00 00 08 34 = 834​

Step 3: Select 04 (byte)
View attachment 178470
Step 4: In HxD I can right click and "Select Block" a byte: type in 926 (yours will/could be different)
View attachment 178472
Step 5: It will highlight a block of code. Copy this and Ctrl+N to make a new file
View attachment 178473
Step 6: Paste the block
View attachment 178474
Step 7: Save the file to ff8slot00.ff8
View attachment 178475
Step 8: Open in hyne

Edit how you like!

Figured it out!

Step 9: After you have made the changes to your save file in Hyne. You will open the save back into your hex editor.

Step 10: You will see the new file size, mine is 00 00 09 21 = 921.
View attachment 178483
Step 11: Copy all the info, Ctrl+A
View attachment 178473
Step 12: Go to the ORIGINAL ff8slot00 file from Step 1.
View attachment 178470
Step 13: On byte 04 in my ORIGINAL ff8slot00 the byte is 22. Highlight that.
View attachment 178470
Step 14: you will now right click and "Select Block" again. Now I would type in 921 as that is my new file size.
View attachment 178484
Step 15: Paste in the new info Ctrl+B (Paste Write)
View attachment 178488
Step 16: This left me with 5 bytes of extra data that was now not needed. I just typed in 00 00 00 00 00. This cleared the info on the end of the save file.

Step 17: Load your save file and if you did it right, you should be able to play the game with your new edits.

Notes: Your save file should be 10,244 when you are done editing. If it is lower or higher, you will need to go in just after your save info and add/delete some bytes. 1 byte per 1 you are off from 10,244. This should fix it if it is not loading or you are getting an error trying to boot the game. This is what happened to me and this is what I did to remedy it.

I hope this helps. Please feel free to message me if you need help!

Thanks! With this guide at least I succeed to convert switch save into pc save and to modify it with Hyne. The problem is to convert back to switch save: I follow all your steps, but when I try to run my save on the switch, it always says the save is corrupted. Maybe I didn't understand the step 16: this is my situation after step 15

I just don't get it if I have to replace all the bytes after the 07 highlighted (my new file size is D0 09 00 00, so 9D0) with 00.

Ok, so when you open the edited files in your hex editor. You will need to look at the file size (first 4 bytes) What is yours?

I am editing mine again right now, and I have 955. So I will copy all the EDITED file (.ff8), then go to the orinigal and on byte 04, I will right click and "Select Block". I will type in 955 in Length. Then right click and "Paste Write". This should give me my new save file size WITH the correct file size of 10,244kb. Does this help?

If your edited file size is SMALLER than the original, you will need to flush the rest of the old file out with 00 00 00 00 00 as much as needed. But, make sure that your full file size at the end is 10,244kb.

Can you post your original save file and your edit file? I can merge them and see if it works for you.

You paste that btye on wrong offset, thats why u get error, or on hyne u add some item etc that make your save damage.

Yes, yesterday I did all the steps perfectly... But this morning I suppose I have found my issue: I added some magic to party members not still available (to be clear, my save is only 7 minutes from the start of the story and I added magic to Irvine ecc.). Indeed, I tried again just adding items, some cards and magic to Squall and everything works fine! Many thanks!

Hey guys, when I convert my retroarch ps1 save file to pc format using Hyne, I end up with a weird hexadecimal number at the beginning of the save file and I'm not sure what size this ends up converting to... Could someone give me a hand?

Makes sense. You sequence broke the game.

Yes it is fine. You just type in 9AE in the "Select Block" Length. But, your save file length is so off 827 original, that you needed to tell the game that your full save file was 03 0A at byte 1. I fixed this. I tested the file and it works fine. Attached! (Remove the .txt from your file before restoring. Had to do this to upload here)

Same thing with you. I just made the 1st bytes 16 0A and this told the game where to find your save file. Tested and works! Your button configuration is throwing me off though, have to admit! lol Attached! (Remove the .txt from your file before restoring. Had to do this to upload here)

And for all those that might like to know. You can definitely go over the 10,244kb "cap". ashtonmachchine's file is 10,739kb and works fine.

For all those that are just starting attached is a fresh new game with 100 of each item. 100 of all items and 100 of all cards except the RARE Gold border named cards. (Character)

File: ff8slot00 (Remove the .txt from your file before restoring. Had to do this to upload here)
