Download HxD (the hex editor I'll be referencing) Open the HxD Open the save in the HxD Edit > Select Block > Select Hex, then Start-offset: 10000 End-offset: 1FFFF > OK. This should select half your save. Now press Delete on your Keyboard. This removes the second half. Now save. It'll prompt you if you want to change file size, and if you want to proceed. Hit OK. Keep this window open (not closed) Now Open another window in HxD. Make a copy of your ROM and keep it safe and unedited somewhere. Load your ROM into HxD. CTRL+G and Go to the address, yours being FC0000. Now go back to your save window CTRL+A and CTRL+C the data. (Select all and copy). Now go back to the ROM window, your cursor should still be at the location. CTRL+B (Paste Write). This overwrites the save in the same location on your ROM. Now save your ROM in HxD. You should not get a prompt to change file size. If so, you did some steps wrong. Now that the ROM is edited, write it back to your cart using the GB operator tool. Make sure you read all the steps carefully. It is all at your own risk.

So when you sent me the save, it was from an old copy of the game yes? Anyway, look at this filename real quick: It says halfpatched. I programmed it to say halfpatched if the save is only half the normal size of Pokemon saves. PKHeX will only accept it if it's twice of that size. So 1) use the halfpatched file in PKHeX and make whatever edits 2) shrink the edited save by half 3) write it back into the ROM where you found it (in this case, 0xFC0000 of the ROM) 4) Flash the edited ROM back to the cart.

Yes. I just tried on my end, and the emulator won't recognize it to. I doubt that this file is a save file. I just looks like garbage, and I reckon you probably read another file. Here's something else I also want you to try. 1. Dump the ROM (don't upload it here) 2. Use this program on said ROM. 3. Upload the saves obtained from the program. because it is a repro cart. Tools usually dump the save partition, but repro carts don't keep saves in the save partition, so it messes up.
