Hacking Metroid Prime 4 Beyond save editing

[Pj1980]

This how to edit Metroid Prime 4 saves. I am not sure save order other than it might be all the manual saves then auto saves. if you have only used one save slot it should be easy to work out. searching for VSM in text might be the start of each save.

Save Editor
There is now a save editor based on the values Genesis_Nova found and py file that OblivionReign created This is link to it. The py file is also attached to this post
https://www.mediafire.com/file/o3mxi7eigt1rpty/mp4_save_editor_enhanced.zip/file
*Save editor can mod each save
*mod items
*mod scans
*odd number saves should be manual and even should be auto, also skips completed saves
Some abilities might need more than one value edited. Check further down after item list if there a note. if you are using editor with a save that as completed save because it dosen't have a scan section it might effect the order of other saves.

Saves Have Checksum
There a Checksum fixer in zip file unzip and drop save onto bat file it will fix the checksum so won't need to use Hxd to fix it. The Checksum fixer uses Bucanero's cli app and a bat file. Bat file is a patch file if you have experience with ps4 save wizard you can add quick codes to it.

Fix Checksum With Hxd

The saves have a checksum it is the first 4 bytes. the next 4 bytes is the whole size of save minus the first 8 bytes if your not changing save size you can ignore this. the checksum covers from after 8th byte or from 35 to end of save. the checksum is CRC-32/JAMCRC. i used hxd to fix checksum. i selected the whole save minus the first 8 bytes you can go into edit and select block. start is 8 and end you can just type ffffff. you then go into analysis select checksum. in generate checksums box select custom CRC (32bit) then select custom crc... in the custom CRC box you need to put 04C11DB7 in poly, FFFFFFFF in intial and in output xor 00000000. also need to tick in and out for reflection. click ok for this and previous box and you should have checksum. the bytes in checksum needs to be reversed you can see in picture below what i mean. both checksum and size are in little endian meaning bytes are reversed.

Editing
To find green shards search for 66 51 03 1A shards will be after that in reverse float. max green shards is 0000af46. also max amount you can have is also after the amount you have so if the id doesn't work you can search for max shard value and go back 4 bytes

it looks like for items its id then amount then cap total repeated twice (so thats 4 byte id and 3 reverse float values). any id with 00 00 80 3F repeated 3 times is probably something unlocked. will need a completed save to see what the right floats should be after the ids.
I don't think id change order so not a problem but if the ids are like the scan section it would be float values then Id

To find scan section search for AF 05 00 00 00 you should find a section similar to whats in picture. all you need to do is put 00 3F in front of the Ids the ids range from 00 to 0A. the 00 ones are easy workout after filling the others in.
As mentioned below changing all might cause a softlock it could be the 0A ones. in picture below in the boxes is the ids

here are some ids i got from a end game save with their float values. I added names that genesis nova found

you can use this site if you want to edit float values just enter decimal value in float value box and tick the box Swap to use big-endian https://gregstoll.com/~gregstoll/floattohex/
There a zip file with bat files that edit green shards it should edit the first auto and manual save you just drop save on to them. you can open them in text editor and change amount they write use the gregstoll site to create hex values you don't have to tick swap.

I deleted the save from this post as it been mentioned 100% scan including every that's scan able could soft lock game. There stuff in game that needs scanning. I think it might be the 0A ones that could cause the softlock assuming none of the logbook ones are mandatory to scan for game progress. Below is the IDs the number of times they are in section and what part of logbook they probably are.
ID - Count - what it could be
00 - 6 - Galactic federation
01 - 4 - Sylux Troops
02 - 53 - Viewros
05 - 19 - Machines
06 - 10 - Larmonian Writings
07 - 17 - Larmonian Records
08 - 18 - Research

Tested a save with just those and they give 100% log book and everything else is green (unscanned). i will let others make starter saves or end game saves.

 

[RokkumanX]

here is a save it's just after getting the psybeam at begining of game on hard mode with 100% scan (can lower difficulty in settings) this is for people who want to save time scanning stuff.

Thank you very much for the save!

Could you make the exact same but with Normal mode instead?

Thank you in advance

 

[Abbie_Doobie]

As a heads up, setting your save to 100% scans breaks certain points in the game. Namely when completing a scan is required to progress. I won't post it here to avoid spoilers, but I did get soft locked and ended up reverting to an older save.

 

[[Truth]]

I posted a save here that is only missing two scans in Viewros section, perhaps it’s easier to find them.

Gaming  Post in thread 'Does anyone have a completed save file for Prime 4? I want hard mode right from the start'

Dec 10, 2025

Anyone with savefile on the point off no return? Mine got stuck right before it

Here is mine:
Slot 1: Mission Complete on Normal difficulty
Slot 2: Right before point of no return, Scans 98%, Items 100%, Crystals 100%, all Amiibo stuff unlocked, Normal difficulty

To get 100% scans, you need to scan the final boss in all their forms and then beat the game.

Thanks @Pj1980 for editing the save.

• [Truth]

Sylux section also missing two scans, but they are not available yet at this point in game.

Will try to edit on my own later.

Spent a little bit of time poking around in the save, adding items and whatnot.
Instructions on what to look for, and what to change are in the OP.
Any "Item IDs" with ??? I did not see any noticable change in the equipment screen.
I did this on a in-progress save, so I did not check items that I had already unlocked, such as Psychic boots, Fire Shot, etc.

This is not an exhaustive list, but just what I've done so far.
There should only be two instances of each set of 4 bytes, first instance is the manual save, second is the autosave.

I can confirm after I manually 'unlocked' every entry that I was soft locked trying to scan a story progression scan.
I took the entire block of scans, marked all 0A scans as unscanned and was able to proceed, still at 100% scan.
Just did a simple replace on any 0A scans that were unlocked.

 

[Abbie_Doobie]

If anyone could figure out a more precise way of locating the missable scans, for me that was the Carvex's Pollen Sac. Didn't miss anything else!

 

[MPRTwice]

here is your save i added those 2 carvex scans to all save slots you were missing i didn't edit sylux ones.

Thanks a lot! May I ask for a 100% logbook scan edit of this, so that I can play on a file just before the final boss with 100% scans already logged?

Oh! This is the ticket. Ignore my last request/post.

Could you give a little more detail on that explainer? I think you are saying that you first marked everything as scanned, then afterward did a hex search-and-replace for 803F0A within the logbook area of the save file, and replaced with 00000A (marking those specific entry types as unscanned)?

edit: fixed the above, I think.

edit: fixed the above, I think.

Basically...
I grabbed the *entire* scan section of the save which I arbitrarily started at AF 05 00 00 like described in the OP, until a random 8A byte at the very end where it stops following the normal pattern.
in HxD the length shows 2D81

You can take that bit of hex and paste it into any decent text editor with a replace feature.
Start with
00 00 00 00 00 00 00 00
replace with
00 00 00 00 00 80 3F 00

Rinse and repeat with these, while also remembering to change the last number in the 'replace' one to match what category you're replacing.
00 00 00 00 00 00 00 01
00 00 00 00 00 00 00 02
00 00 00 00 00 00 00 05
00 00 00 00 00 00 00 06
00 00 00 00 00 00 00 07
00 00 00 00 00 00 00 08

After you're done with that, you can overwrite paste that back over the same selection (Control + B in hxd)
Fix your crc at the start of your save, and it should load fine afterwards.

Other than this, I'm not going to be really going into more depth, I'm just poking around for item IDs and whatnot.

Do a search, switch to the hex tab and search for

You should see some results in the bottom.

There are only two that will do what you want, For me, it was the third from the top (This is the manual save scans).
Yours may be different, but its the first result with "00 00 00 00 0A" after AF 05 00 00.
The one at the very bottom is for the autosave scans.

After you've found the spot for your scans, do what I said before, paste the changes back in, fix your crc like described in the opening post, and then it should work.

Thank you for being patient, so this is what I know so far...

...and now my goal is to edit in the remaining scans. Reading through the notes, it appears that sylux has an 01, but I do not currently know how to make use of that information. May I please ask for another hint? I would greatly appreciate it; my goal is to edit a save, based on the previous end of game 98% scans upload, to have 100% scans but not softlock.

You're not going to simply be able to replace all the scan entries in hxd, there are too many other things that aren't scans that would be affected, which is why I said to copy the scan section out to another text editor.

As I had said above you can copy from the AF 05 00 00, all the way down to where the 'pattern' for the scans stops, there's a "8A" byte where I decided to stop.
At the bottom of HXD it'll show you how large your highlighted area is, it should read 2D81.

 

[Pj1980]

you can search for this AF 05 00 00 00 00 to reduce results to just scan section.
the offsets for the 00 scans from AF 05 (but it shouldnt be hard to find as ids line up)

I learned how to copy/paste in Hxd, and how to replace exact segments of:

Start with
00 00 00 00 00 00 00 00
replace with
00 00 00 00 00 80 3F 00,

but it still gives me a corrupt save error. I checked to see if any improper replacement of hexadecimal occured, and the file length is the same, so I am not sure where I made an error:

Step 1: Open the .sav in HXD

Step 2:

Then a "save is corrupt" message. Where did I make the error, if I may ask? Thanks.

You did not fix your CRC at the very beginning of the file.
Any time you make a single change in the save file, you have to fix the checksum because it changes.
Its right in the original post, bolded "Fix Checksum"
