Do you think there's a save game edit you can do to make it that save stations refil ammo on hard mode?

Or is that more of a mod?
Its rough but if you want i made a small editor using what you have? modify it if you will to your findings. hope it helps. it will correct your checksum too.
Your description of data was a lil weird so i didnt use any specific patterns atm aside from the exact AOB you gave for each in your list lol

Just the way i formatted it based on what they provided in their blurb. can fix if you want
Are you still working on the save editor? Will you be adding more items to it like energy tanks and green shards?
Post automatically merged:
Cause im on hard mode right now and I could really use the upgrades
If you guys find more values in the save data then i can add and correct things. i didnt bother to parse the save data myself. just quickly put this together based on what op has put up
What items are safe to add to an early game save? For example volt forge tower 2 before turning on the second generator?

Im wondering this because I need help in hard mode

Post automatically merged:
im having some trouble in hard mode can you give me some items to help me out?
the checksum works but stuff without a name might not be connected to what comes before, i have added genesis nova info to first page. I converted py into app using pyinstaller as well as use the updated ids. https://www.mediafire.com/file/6a6anzvua3zcpmg/editor.zip/file
depending on how many slots are filled there will be 2 instances per slot so there will either be 2, 4 or 6 of each. also here is the py file. is it possible to search for a value then have multiple offsets from it.
Last edited by Pj1980,
I have edited the first two on some of the items that aren't a max of 1, such as missiles, shot ammo, and power bombs, and that does track when what I've seen. I saw no reason to look into increasing the third value.
For example here's my current save file's power bomb section.
F4 B9 C7 84 00 00 00 00 00 00 80 40 00 00 00 41
I have 0 current power bombs
Current max of 4, with 8 max allowed by the game.
These are the offsets from AF 05 00 00 00 00 for the different scans

2D14 ViewrosIs this editor updated from the one you showed me yesterday? Does it include other things like log book entries?
yes editor is updated it now shows different saves and you can edit log scans, check the first post. i used claude.ai to add stuff to original py file like offsets and separate stuff into individual saves. it dose list saves as save 1, save 2 and so on. the odd numbers should be manual saves and even auto saves. Save editor skips completed saves.

Btw the psychic grapple i added into my inventory doesn't work apparently there's probably another code to activate it like power bombs
